To buy, or Not to buy? That is the qeustion??

Before the Ipad came out, I was seriously considering getting a Netbook. I already have a Laptop and Desktop at home. Waiting for the Ipad 3g to come out and considering to buy the 64gb one. Have read reviews that all the Ipad is is a glorified Iphone. It no where compares to a netbook and a lot of people have been disappointed. I know it's not going to be like a laptop but I am looking to use it for school (word processing and such) as well as entertainment and personal use! Before I spring for $800 should I wait for something better or just go for it?? I hate being the guinny pig when something new comes out and spend soo much money on something where a year later a better one is out! Any adivice?

This isn't directed at you, Tiffany, but all I can say is that negative reviewers are certainly entitled to their opinions. And with that said, I say they don't know what they're talking about. Either they're so enslaved to some preconceived idea or need that they can't see the iPad for what it is, or their needs seem to run counter to virtually everyone else's. Who would not want a computer of this magnitude with this degree of ultra portability? If someone says that, "Yeah, but I can do all that and more on my tablet computer," I say yes, but can you do it by just pulling out a 24 ounce slate the size of a small magazine, turn it on instantly and do everything right there on the screen resting comfortably in your lap requiring nothing else and do it for the next ten hours without a power cord? Can you interface with your tablet with the ease with which one can interface with the iPad? Can you almost immediately find and download a program for virtually any need you can think of and be using that program within seconds, usually? Well, can you?
There is nothing and never has been anything before like the iPad. The sheer extent of it's portability coupled with that gorgeous almost ten inch screen that is really the entire computer, make it thrillingly unique. I've been using it since I got it that first Saturday. The virtual keyboard I find easier to use than real ones. It's a joy, which is a real surprise. The only other Apple I've ever owned is my iPhone, although I'm comfortable on Macs. This device transcends any so called loyalties, however. A winner is a winner.
Don't think it's for you, naysayers, fine. But don't even bother trying to tell me anything otherwise. I'm sorry you can't see the enormity of what's going on with the iPad. One thing to keep in mind, it's only going to keep developing and advancing. The amount of creative energy this thing will release to feed it's complete open endedness is kind of awesome to contemplate. Frenzy is the only word that comes to mind. If sitting on the sidelines of such an event makes you feel better, then you're welcome to it. The rest of us will be sending you emails from the 21st Century that you can blithely read on your 20th Century machines.

  • To buy or not to buy an entry level 13in MBP? Have a 30in display I would like to connect it to for photo editing and a little video. Any advice?

    In the last year the logic board in both my 17in MBP (5yrs old) and Mac Pro (4yrs old) have died.  The local techies have advised due to cost and age that replacing them would not be worth it in the long run.
    I am thinking to buy the most basic MBP and connecting it to my 30in cinema display would give me the best of both worlds - a desktop option when at home and a laptop for travelling.  Is this a viable option?  I would be using it for photo editing (photoshop) mainly and a little video editing with Final Cut Pro when connected to the cinema display and a little light internet usage, emails and such when on the go. 
    My other question is, do all MBP come with airport/wireless capabilities as standard?  (I had to purchase airport separately when I bought the other computers.
    Thanks in advance

    The 13" MBP is c**p, it's a consumer MacBook quality in a silver case with a "Pro" sticker, comes with poor integrated graphics that overheat when it even looks at a web video, all shiny screens poor for video. Scores a mere 11 on Cinebench.
    Like Sig said, 15" 2.0 (scores 18) or better, 2.2 (scores a decent 30) or better preferred, it has the hefty video card you need to power the external monitor.
    also you get a anti-glare option, excellent for avoiding glare and reflections in portable uses.
    also you may need the quad core i7 for processing video faster, dual cores are toast.
    17" high res has true 1920 x 1080 (1080i) with it's 1920 x 1200 pixel screen, I've got one. Sweet.
    Sad to hear you have been having such a bad run with Mac's, it used to be they lasted 5-7 years or longer easy.

  • To buy or not to buy 17" Mac Book Pro

    I'm in the market for a new latpop, probably a 17" to have as a offline editor for FCP. I've seen in the website that they have a new model, but, aside from being able to put 4 gigs of ram and have a better display, are the Intel processors much better than the 2.33? Intel Core 2 Duo, means you have two processors instead of one? and finally, has anyone heard if they are coming out with a Dual-Core Intel Xeon processors like the ones on the G5 on the laptops?
    My apologies for so many questions, any info will help.
    Thank you,

    Carry on... it has 1.4" more length and its about an inch of depth/longer more than a 15" laptop, so it's not much bigger than the 15" laptop. I guess its about priorities, don't know exactly how much gear overall you are taking with you, but, if you buy the 17" laptop with its enhanced monitor ($100 bucks more) you get the same 1920 x 1080 of a 20" monitor, and you have less gear. Anyways, I try not to use to much the computer on a plane, I can't really work in a plane, unless I'm in first class, which hardly ever happens. Oh, and you have no problem carry on the laptop in a plane, it's easy. As you probably know people take things much bigger than a laptop on a back pack.
    Good luck,

  • To buy or not to buy WebLogic Portal

    Hi Folks,
    We are facing a tough decision, we have resources for WebLogic Portal but are not sure whether to buy this product for our company to do our intanet, broker portal and supplier portal.
    Oracle says Webcenter is their strategic product but we dont have any resources in this country for Webcenter so that is not an option.
    Oracle also have not made it clear what the future of WebLogic portal is, besides for the "Continue & Converge" statement and the "9 years support" statement.
    Could anyone please help us with information around the future of WebLogic Portal?
    Thanks,

    Hi,
    I am working in WL and WLP since version 3.1.0 since year 2000. Its going nowhere. It is the market leader and now after WL 9.0, integrated ecliplse environment, it is better than ever. I have worked and working for fortune 10 clients and they have long term roadmap. After Oracle taking over Weblogic, its better for Weblogic. It will find a much bigger customer base, a much bigger financial stability, much larger integration capabilities, better support and marketing. OAS is not comparable to WL so I dont think Oracle is going to market OAS over WL and they will project WL as the production server. And now with 2.0 and WL already fully geared to support it, it will emerge as best Application Server. I have worked in other competitive AS also but none compared to WL. If you are going to Open Source AS like JBoss, then its different story alltogether. Although in near term, due to intergation of BEA and Oracle there might be small hiccups but we all know Oracle is a master of integration and now buying and merging companies is in their veins.
    Talk to WLP sales guy about road map.
    Best of luck !

  • To buy or not to buy LENOVO 3000 N200

    Hello!
    At first I am from slovenia that's because mi english is not so good  
    I am buying a laptop for school (photoshop, programming, movies ) and i found the lenovo N200 in our store
    http://www.bof.si/sl/product.cp2?guid=6F2B85B9-3CEA-CE25-1DA7-3D02A9C4EF0D&linkid=15.
    I became interested in this laptop but i have some questions:
    - Is the fan noise a pain in the ass? Because of it's on-off function.
    - Is the housing durable for caring it around in a backpack? Is it well made?
    - Does the this battery have the same problem as the n100 model?
    - Any reasons why not to buy it?
    Thans for you help and keep up the good work.

    Here is my experience based on owning a Lenovo 3000 N100 laptop:
    Thinkpads are built very sturdy.  The "consumer level" laptops, ie the 3000 models, are nothing special.  In fact, I would not recommend the 3000 model to anyone.  In my personal experience, the 3000 models are plagued with engineering errors.  The motherboards have defects that render the USB ports useless (my USB ports are dead).  Many of the batteries need to be recalled (my battery failed).  If they do recall your battery, they will not notify you (they did not notify me).  You'll have to come to a website like this and search for details (this website is awsome).  The laptop case is weak and flexes much like any other cheap laptop on the market.  The power supplies are underpowered (my 65W supply sure gets hot)..  Other than those 4 defects, my machine works fine.
    Don't be fooled into thinking the 3000 series is anything like the Thinkpads in terms of reliability or service; they are not.  You have to pay good money for a good laptop; hence the Thinkpad series.
    Good luck.

  • To buy or not to buy a rMBP?

    Hi everyone!
    This is my first question on the forum, so apologize if I'm asking something that has been asked a ton of times.
    I was however unable to find a similar thread.
    My problem is not whether or not I should buy a Retina Macbook Pro, but rather when.
    At the moment I'm on a 2½ month roadtrip throughout the US and got about 3 weeks left or so.
    I was kind of hoping for an updated rMBP, so I could pick it up in Oregon when I'm going there in a few days. (They do not have a state tax)
    There is a lot of money to be saved by buying it while I'm in the states as they are 500-700 dollars more expensive back in Denmark.
    My problem is that I've been reading several places that an update to the rMBP is expected within the next few weeks.
    I know very little about computers and will only be using the rMBP for studying and photo and video editing and the usual internet surfing.. A little gaming here and there, but is by no means a priority.
    Therefore I do not know how much of an update there is to expect and could really use some help to figure out what to do.
    Should I buy a retina Macbook Pro while in the states and risk it being outdated within a few weeks - but save 500-700 dollars
    ... or should I wait for an update and buy it in Denmark and pay the extra price?
    If you need any other information, please let me know!
    Thanks

    If your main concern is only the network connection, Mac and PC use the same "language" for example TCP/IP, wireless 11 B or 11 G, only the setting and approach might be slightly different, probably this is you afraid most, no one will help you to set it up when it fails.
    If there is also specific software involved that Mac side cannot open and or will create problem during file swapping and transfer, I agree with powerpig, get a dedicated PC instead, it will create you less hassle and you speak the same with other collaguae. And no more scapegoat like" I cannot do my homework since my Mac cannot open the program".
    Even though there is many alternative to open xp files by similar programs from different developer on mac side, but why bother to convert the instruction etc, when you can get the easy way with xp school environment, unless you are a Mac dedicated lover or you want to become one.
    You can buy a MacBook, use it as "Jeckyl and Hyde" using boot camp, XP in the day and Mac OS in the night, but will you spend extra money to buy a licensed XP for your Mac Boot Camp.
    If you afraid of having bad experience using xp, I believe your school has support for it, at least first aid support.
    the decision is up to you, read more thread won't hurt and you'll learn a thing or two.

  • To buy or not to buy-applecare plan

    as a first time buyer of iphone should i buy applecare for $69 as well? will it cover screen spiderwebs, as my bro did to his? please advise

    No, it will not cover broken glass from dropping the phone... what it WILL do is extend the normal 1-year warranty to 2 years. That includes the battery, manufacturing defects, essentially anything that would result in Apple replacing or repairing your phone within the first year would be covered for the additional year. I get AppleCare on pretty much every Apple product I get- on the rare occasion that I've had to use it, it's more than paid for itself.

  • Mac to buy or not to buy

    is it worth buying a mac book? I know this us a support discussion so um asking for just that. I have a pc w/ vista. Its a year old compaq. Use it mostly for school n entertainment. How does it compare to a mac book. I'm looking at the one that is 1099. Pc vs mac what major differences? Pros n cons of it. Anyone think mac is over hyped? Software? Pls be honest n response. Thanks in advance

    well lets see where to start. well you say you have a compaq running vista, comparing that to a macbook i would say the macbook would be better for entertainment. the macbook is very powerful yet very portable. the macbook includes i life 08 which had itunes(a music software),iphoto(photo editing and storage software), imovie(movie making software),garageband(music making software),idvd(dvd making software),and iweb(website publishing software). these are all included with the macbook when you buy it. A compaq running vista of course dosnt come with all of this great software. including the fact that overall the macbook features MacosX10.5 leopard which is way better than vista in my opinion, id say that a macbook would be the choice for you. well i hope this answer helped a little .

  • To buy or not to buy ipad air

    Not exactly a "user" question.  I am new to this and didn't know how to post to the category I wanted.
    Anyway, Have never had a tablet.  Am considering the ipad air.  Have seen lots of discussion about freezing and crashing.  Has this problem been fixed yet.  If not, is there a particular touter that solves the problem, or a particular set up that fixes things.  I like the air, however am worried about this wifi problem.  I don't think the Samsung Galaxy 10 or the Nexus 10 has this crashing problem.
    Help me to get this air and not have crashing and freezing problems.
    Thanks

    The reason you see far more reports about iPads crashing is that they are more popular. Yes, iPads crash (rarely). So do Samsung tablets, Nokia Tablets, Mac computers, Windowns computers. I've had an iPad Air for a couple of months now. It has worked perfectly. I don't recall it ever crashing and I don't do anything special to keep it from doing so.

  • My iphone was working normally ando today...it turned off and....i'm trying to turn on...buy is not working...and the cell phone is hot hot hot...someone can help me please??

    when i plug the cell phone in my computer...the computer doesn't aceppet the cell phone..so...i can't restore my iphone...
    i press both bottons...and...is not working....

    The recovery mode sound like your best option and unfortunatly everything will be lost unless you did a back up of your device recently make sure you have a computer running itunes 11.1.1 plug in the usb to the computer and after that power your device off by holding the sleep/ wake button until it says slide to power off and then slide to power off after that press and hold the home button while holding the home button connect your device to the computer continue to hold the home button until connect to itunes shows on the phone. on the computer it will say itunes has reconized a device in recovery mode just click through the menu to get your device to back to new

  • To Mac, or not to Mac, that is the question...

    Okay, so I don't know if I'm allowed to ask this in this forum, but I'll give it a try anyway.
    I will be starting college in the fall and will need a computer. I've had myself convinced for a while now that I want a MacBook...but now I'm starting to have second thoughts.
    It's just that I've always used PCs in my life, I know how to do anything I want really on a PC, and I don't know if it's worth the bother to relearn a whole new system. Plus, I mean, I'm starting college, I should know how to use my computer before going, don't you agree? Just how hard is it to adjust?
    Another issue is the whole windows/mac os thing in that I'm worried about programs running on it. I don't really understand how Boot Camp works. You just install Windows XP (do you have to buy it? is it a special mac version?) and your Mac turns into a Windows machine? As in it looks just like my HP lap top looks now, wiht the bar at the bottom, etc.? But then I've read some posts on these threads and ppl say you could get viruses that way b/c you are using windows. Which is one of the reasons I would want to switch to a mac. If you do use Windows and the Mac OS, you can just switch back and forth whenever you want? Are all the programs and files the same then in both systems? Like I wouldn't want half my files to be in one program and the other half in another. I don't know, I don't really understand it all.
    Also, my mom got a MacBook and I guess they bought a new laser printer yesterday and had to return it today b/c they realized it's not apple compatible. They went to Office Max and realized barely any printers are apple compatible! The had the toughest time finding an affordable printer that they liked! How can this be? Is this how it's always going to be when I'm buying accessories?
    I just love all the features the Mac has. I am constantly frustrated w/ Windows and all the **** viruses and adware I have on my computer, which is a major reason for my wanting to switch. FrontRow seems like the coolest thing ever. And the cool magnet things. And I already have an iPod, so they'd run nicely together. Plus, it's pretty. (I know it's a dumb reason to buy a computer, but I'm a girl, what can I say, that stuff is important to me.)
    So anyway, I'm now debating between a MacBook and a tablet PC, possibly Gateway or IBM. Could anyone try to convince me one way or the other (considering I'm on a Mac discussion board, I'm sure it'll be the Mac way)? Thanks everyone, I really appreciate your help.

    My guess is that you're likely to find more Mac users at a college than most other areas, so I wouldn't worry too much about 'making the switch' right before going to college -- you'll have lots of help nearby.
    Boot Camp is pretty cool!
    It's a free utility from Apple that basically prepares your Mac so it can run Windows XP. Boot Camp divides your hard drive into seperate areas (partitions) -- one for OS X and another for XP. Boot Camp doesn't come with a copy of Windows XP -- you'll need to provide that. The XP that Boot Camp installs isn't a special version for Mac -- it's the same version that runs on any computer, although to work with Boot Camp, you'll need an XP install CD that has Service Pack 2 applied. Once XP has been installed on your Macbook, it should look (and act) like XP on your HP (with the exception of any special tools/programs that HP loaded on your HP laptop, obviously).
    When you restart your MacBook, it will boot into whichever OS that you set as the default. If you want to boot into the other OS, you just hold down the OPTION key when you restart and then you pick which OS to load. Your computer is basically divided into two systems, so no, programs are not automatically on both systems. If you install the Mac version of Microsoft Office in OS X, you're not going to have Excel/Word/etc when you boot into XP unless you specifically install the Windows version of Microsoft Office.
    Regarding accessories, you always need to check that they work with OS X. My printer was a problem too. It was an el cheapo Samsung laser printer and Samsung apparently didn't feel like spending the money to write OS X drivers for it, but it turned out that an older Samsung OS X driver worked just fine. I had zero problems getting my Kodak camera to work -- I just plugged it in an OS X started using it ... no drivers to install or anything, which made it way easier than the crap I had to do in XP to get XP to see it. My iPod nano worked with no problems too.
    I really, really love my MacBook. I don't know when you have to make your decision, but try using your moms as much as you can (if you can). I bought a Mac mini for my other half last year (birthday present). I had NO interest at that time in Macs or OS X, but after a few days of watching over his shoulder, I was hooked and got myself a mini (and then a PowerBook and then a MacBook Pro and then a MacBook) .. it's addicting.

  • To RAID or not to RAID, that is the question

    People often ask: Should I raid my disks?
    The question is simple, unfortunately the answer is not. So here I'm going to give you another guide to help you decide when a raid array is advantageous and how to go about it. Notice that this guide also applies to SSD's, with the expection of the parts about mechanical failure.
     What is a RAID?
     RAID is the acronym for "Redundant Array of Inexpensive Disks". The concept originated at the University of Berkely in 1987 and was intended to create large storage capacity with smaller disks without the need for very expensive and reliable disks, that were very expensive at that time, often a tenfold of smaller disks. Today prices of hard disks have fallen so much that it often is more attractive to buy a single 1 TB disk than two 500 GB disks. That is the reason that today RAID is often described as "Redundant Array of Independent Disks".
    The idea behind RAID is to have a number of disks co-operate in such a way that it looks like one big disk. Note that 'Spanning' is not in any way comparable to RAID, it is just a way, like inverse partitioning, to extend the base partition to use multiple disks, without changing the method of reading and writing to that extended partition.
     Why use a RAID?
     Now with these lower disks prices today, why would a video editor consider a raid array? There are two reasons:
    1. Redundancy (or security)
    2. Performance
    Notice that it can be a combination of both reasons, it is not an 'either/or' reason.
     Does a video editor need RAID?
    No, if the above two reasons, redundancy and performance are not relevant. Yes if either or both reasons are relevant.
    Re 1. Redundancy
    Every mechanical disk will eventually fail, sometimes on the first day of use, sometimes only after several years of usage. When that happens, all data on that disk are lost and the only solution is to get a new disk and recreate the data from a backup (if you have one) or through tedious and time-consuming work. If that does not bother you and you can spare the time to recreate the data that were lost, then redundancy is not an issue for you. Keep in mind that disk failures often occur at inconvenient moments, on a weekend when the shops are closed and you can't get a replacement disk, or when you have a tight deadline.
    Re 2. Performance
    Opponents of RAID will often say that any modern disk is fast enough for video editing and they are right, but only to a certain extent. As fill rates of disks go up, performance goes down, sometimes by 50%. As the number of disk activities on the disk go up , like accessing (reading or writing) pagefile, media cache, previews, media, project file, output file, performance goes down the drain. The more tracks you have in your project, the more strain is put on your disk. 10 tracks require 10 times the bandwidth of a single track. The more applications you have open, the more your pagefile is used. This is especially apparent on systems with limited memory.
    The following chart shows how fill rates on a single disk will impact performance:
    Remember that I said previously the idea behind RAID is to have a number of disks co-operate in such a way that it looks like one big disk. That means a RAID will not fill up as fast as a single disk and not experience the same performance degradation.
    RAID basics
     Now that we have established the reasons why people may consider RAID, let's have a look at some of the basics.
    Single or Multiple? 
    There are three methods to configure a RAID array: mirroring, striping and parity check. These are called levels and levels are subdivided in single or multiple levels, depending on the method used. A single level RAID0 is striping only and a multiple level RAID15 is a combination of mirroring (1) and parity check (5). Multiple levels are designated by combining two single levels, like a multiple RAID10, which is a combination of single level RAID0 with a single level RAID1.
    Hardware or Software? 
    The difference is quite simple: hardware RAID controllers have their own processor and usually their own cache. Software RAID controllers use the CPU and the RAM on the motherboard. Hardware controllers are faster but also more expensive. For RAID levels without parity check like Raid0, Raid1 and Raid10 software controllers are quite good with a fast PC.
    The common Promise and Highpoint cards are all software controllers that (mis)use the CPU and RAM memory. Real hardware RAID controllers all use their own IOP (I/O Processor) and cache (ever wondered why these hardware controllers are expensive?).
    There are two kinds of software RAID's. One is controlled by the BIOS/drivers (like Promise/Highpoint) and the other is solely OS dependent. The first kind can be booted from, the second one can only be accessed after the OS has started. In performance terms they do not differ significantly.
    For the technically inclined: Cluster size, Block size and Chunk size
     In short: Cluster size applies to the partition and Block or Stripe size applies to the array.
    With a cluster size of 4 KB, data are distributed across the partition in 4 KB parts. Suppose you have a 10 KB file, three full clusters will be occupied: 4 KB - 4 KB - 2 KB. The remaining 2 KB is called slackspace and can not be used by other files. With a block size (stripe) of 64 KB, data are distributed across the array disks in 64 KB parts. Suppose you have a 200 KB file, the first part of 64 KB is located on disk A, the second 64 KB is located on disk B, the third 64 KB is located on disk C and the remaining 8 KB on disk D. Here there is no slackspace, because the block size is subdivided into clusters. When working with audio/video material a large block size is faster than smaller block size. Working with smaller files a smaller block size is preferred.
    Sometimes you have an option to set 'Chunk size', depending on the controller. It is the minimal size of a data request from the controller to a disk in the array and only useful when striping is used. Suppose you have a block size of 16 KB and you want to read a 1 MB file. The controller needs to read 64 times a block of 16 KB. With a chunk size of 32 KB the first two blocks will be read from the first disk, the next two blocks from the next disk, and so on. If the chunk size is 128 KB. the first 8 blocks will be read from the first disk, the next 8 block from the second disk, etcetera. Smaller chunks are advisable with smaller filer, larger chunks are better for larger (audio/video) files.
    RAID Levels
     For a full explanation of various RAID levels, look here: http://www.acnc.com/04_01_00/html
    What are the benefits of each RAID level for video editing and what are the risks and benefits of each level to help you achieve better redundancy and/or better performance? I will try to summarize them below.
    RAID0
     The Band AID of RAID. There is no redundancy! There is a risk of losing all data that is a multiplier of the number of disks in the array. A 2 disk array carries twice the risk over a single disk, a X disk array carries X times the risk of losing it all.
    A RAID0 is perfectly OK for data that you will not worry about if you lose them. Like pagefile, media cache, previews or rendered files. It may be a hassle if you have media files on it, because it requires recapturing, but not the end-of-the-world. It will be disastrous for project files.
    Performance wise a RAID0 is almost X times as fast as a single disk, X being the number of disks in the array.
    RAID1
     The RAID level for the paranoid. It gives no performance gain whatsoever. It gives you redundancy, at the cost of a disk. If you are meticulous about backups and make them all the time, RAID1 may be a better solution, because you can never forget to make a backup, you can restore instantly. Remember backups require a disk as well. This RAID1 level can only be advised for the C drive IMO if you do not have any trust in the reliability of modern-day disks. It is of no use for video editing.
    RAID3
    The RAID level for video editors. There is redundancy! There is only a small performance hit when rebuilding an array after a disk failure due to the dedicated parity disk. There is quite a perfomance gain achieveable, but the drawback is that it requires a hardware controller from Areca. You could do worse, but apart from it being the Rolls-Royce amongst the hardware controllers, it is expensive like the car.
    Performance wise it will achieve around 85% (X-1) on reads and 60% (X-1) on writes over a single disk with X being the number of disks in the array. So with a 6 disk array in RAID3, you get around 0.85x (6-1) = 425% the performance of a single disk on reads and 300% on writes.
    RAID5 & RAID6
     The RAID level for non-video applications with distributed parity. This makes for a somewhat severe hit in performance in case of a disk failure. The double parity in RAID6 makes it ideal for NAS applications.
    The performance gain is slightly lower than with a RAID3. RAID6 requires a dedicated hardware controller, RAID5 can be run on a software controller but the CPU overhead negates to a large extent the performance gain.
    RAID10
     The RAID level for paranoids in a hurry. It delivers the same redundancy as RAID 1, but since it is a multilevel RAID, combined with a RAID0, delivers twice the performance of a single disk at four times the cost, apart from the controller. The main advantage is that you can have two disk failures at the same time without losing data, but what are the chances of that happening?
    RAID30, 50 & 60
     Just striped arrays of RAID 3, 5 or 6 which doubles the speed while keeping redundancy at the same level.
    EXTRAS
     RAID level 0 is striping, RAID level 1 is mirroring and RAID levels 3, 5 & 6 are parity check methods. For parity check methods, dedicated controllers offer the possibility of defining a hot-spare disk. A hot-spare disk is an extra disk that does not belong to the array, but is instantly available to take over from a failed disk in the array. Suppose you have a 6 disk RAID3 array with a single hot-spare disk and assume one disk fails. What happens? The data on the failed disk can be reconstructed in the background, while you keep working with negligeable impact on performance, to the hot-spare. In mere minutes your system is back at the performance level you were before the disk failure. Sometime later you take out the failed drive, replace it for a new drive and define that as the new hot-spare.
    As stated earlier, dedicated hardware controllers use their own IOP and their own cache instead of using the memory on the mobo. The larger the cache on the controller, the better the performance, but the main benefits of cache memory are when handling random R+W activities. For sequential activities, like with video editing it does not pay to use more than 2 GB of cache maximum.
    REDUNDANCY(or security)
    Not using RAID entails the risk of a drive failing and losing all data. The same applies to using RAID0 (or better said AID0), only multiplied by the number of disks in the array.
    RAID1 or 10 overcomes that risk by offering a mirror, an instant backup in case of failure at high cost.
    RAID3, 5 or 6 offers protection for disk failure by reconstructing the lost data in the background (1 disk for RAID3 & 5, 2 disks for RAID6) while continuing your work. This is even enhanced by the use of hot-spares (a double assurance).
    PERFORMANCE
     RAID0 offers the best performance increase over a single disk, followed by RAID3, then RAID5 amd finally RAID6. RAID1 does not offer any performance increase.
    Hardware RAID controllers offer the best performance and the best options (like adjustable block/stripe size and hot-spares), but they are costly.
     SUMMARY
     If you only have 3 or 4 disks in total, forget about RAID. Set them up as individual disks, or the better alternative, get more disks for better redundancy and better performance. What does it cost today to buy an extra disk when compared to the downtime you have when a single disk fails?
    If you have room for at least 4 or more disks, apart from the OS disk, consider a RAID3 if you have an Areca controller, otherwise consider a RAID5.
    If you have even more disks, consider a multilevel array by striping a parity check array to form a RAID30, 50 or 60.
    If you can afford the investment get an Areca controller with battery backup module (BBM) and 2 GB of cache. Avoid as much as possible the use of software raids, especially under Windows if you can.
    RAID, if properly configured will give you added redundancy (or security) to protect you from disk failure while you can continue working and will give you increased performance.
    Look carefully at this chart to see what a properly configured RAID can do to performance and compare it to the earlier single disk chart to see the performance difference, while taking into consideration that you can have one disks (in each array) fail at the same time without data loss:
    Hope this helps in deciding whether RAID is worthwhile for you.
    WARNING: If you have a power outage without a UPS, all bets are off.
    A power outage can destroy the contents of all your disks if you don't have a proper UPS. A BBM may not be sufficient to help in that case.

    Harm,
    thanks for your comment.
    Your understanding  was absolutely right.
    Sorry my mistake its QNAP 639 PRO, populated with 5 1TB, one is empty.
    So for my understanding, in my configuration you suggest NOT to use RAID-0. Im not willing to have more drives in my workstation becouse if my projekts are finished, i archiv on QNAP or archiv on other external drive.
    My only intention is to have as much speed and as much performance as possible during developing a projekt 
    BTW QNAP i also use as media-center in combination with Sony PS3 to run the encoded files.
    For my final understanding:
    C:  i understand
    D: i understand
    E and F: does it mean, when i create a projekt on E, all my captured and project-used MPEG - files should be situated in F?  Or which media in F you mean?
    Following your suggestions in want to rebulid Harms-Best Vista64-Benchmark comp to reach maximum speed and performance. Can i use in general the those hardware components (exept so many HD drives and exept Areca raid controller ) in my drive configuration C to F. Or would you suggest some changings in my situation?

  • To i7 or not to i7 - that is the question

    OK, so my motherboard has given up the ghost pretty much. The PCI slots and soundchip have failed - possibly a southbridge problem (listen to her chatting like she knows what she's talking about  )
    I am thinking I will buy a new socket 939 motherboard to tide me over but my mind has been swayed by the Intel Core i7 CPU which I hear is streets ahead of even the latest AMD Phenoms. My reason for buying it would be to get a PC together that would at least last me a few years and still be relatively current. Not like when I thought socket 939 was the new thing and like literally the next month they announced a new type of socket CPU - confound them - *shakes fists angrily*
    My question compared to my current CPU AMD 3200+ socket 939 2.0 GHz will I really notice a huge difference in using everyday programs by upgrading to an i7 (the top of the range 3.0GHz one)?
    Should I bother upgrading now or leave it at least until maybe next year?
    Is i7 really any good?

    Quote from: munchkette on 15-July-09, 18:54:01
    So anyone got any recommendations on the best memory from this list for an i7 motherboard?
    http://www.eclipsecomputers.com/subcategories.aspx?subcat=440&subcatname=DDR3&cat=23
    I am not particularly bothered about over the top memory, just functional and reliable and those above look cheap.
    This is what I love about computers. When I was making my i7 purchase I had no idea what type of memory I should get. I was familiar with the solid brand names and I was looking for reliability and ability to replace defective parts. Corsair offers a life time warranty for their memory and this was a big selling point for me. I went with the DDR3-1600 6gb kit as I had heard this was what the i7 965 liked to run. (I had planned on OC'ing my 920 to the 965 frequency)&(I was going to run in triple channel so it was either 3gbs or 6gbs).
    After researching numerous articles and looking over many analytical graphs I reached the conclusion (along with other users doing research) that real world benefits of DDR3-1600 compared to DDR3-1333 or even DDR3-1600 vs 1066 are very minuscule. In terms of video applications, you will see a frame rate difference of 2-5fps.
    I bought the Dominator 6gb kit native at DDR3-1600 because of the brand name reliability and I will admit because of the marketing ploy. I liked the name 'Dominator' (it just seemed to fit so well with my new beast i7 machine), I liked the look of the memory, the size of the kit, and I thought because of the overclock ability. I built the machine and then asked myself...Is it worth running the memory at 1600 which requires 1.65 volts or run the memory at 1333 or below with tighter timings and less voltage. After doing more research I found that my MSI board runs native at DDR3-1333. I want to make sure this rig lasts at least 4 years for me. I live in Louisiana where heat is always a problem so my system is always being stressed. I didn't want to add over voltages to a heat problem. This is my own reasoning. If you feel fine to run 1600 at 1.65v then do it. I don't want to ride the edge of the knife and find one day my system is fried.
    I will have many detractors say that more bandwidth is always better! In synthetic benchmarks this may be true, however real world benefits are low. Selling the Dominator 6gb set at DDR3-1600 is nothing more than a marketing ploy. OEM i7 920s and 940s(before phaseout) could not change the multiplier.  OEM test bed processors were locked at 1066 regardless the memory you bought. This meant you wasted that money on DDR3-1600 memory, but could never achieve that rate. The retail i7 920s+ are unlocked and you can change the multiplier to you hearts content. However, it is overclocking and you could run into stability issues. If you don't feel safe with changing voltages and taking the time to find a stable system, I would recommend you run your memory at DDR3-1333.
    My advice to you would be to find reliable memory at a decent price. I like Corsair, but they are more expensive. I have had some good luck with patriot memory in the past. From my sig, running DDR3-1333 Dominator 6gb (3x2gb)@ DDR-1333 at 1.6v. Timing 6-6-6-15 1CR. I really notice a difference between 6-6-6-15 and the XMP set 8-8-8-24@DDR3-1600. Everything feels more crisp and responsive at the tighter timings.
    So go read some articles. Don't ask which is better, higher bandwidth or tighter timings. This has been a long, ongoing debate in the community. Do some research and then you can make the decision for yourself. I am very happy with my current setup and it is absolutely everything I need! (well I could use another EVGA card for SLI, but that's another story )

  • 24P or not to P, that is the question...

    I was hoping someone could clarify the significant importance of buying a 24P camera in which the footage is going to end up on a NTSC SD DVD. I filmed footage for a film shot with a Canon HV20 in the 24P mode. The footage looks fantastic after you put it through Compressor and get 24fps.
    To me this is all irrelevant however, I'll explain. After you shoot on the HV20 it records as 29.97fps. It is not 24fps until you pulldown the remaining frames in Compressor.
    Would I have been better off just shooting on the 24P mode at 29.97fps and leaving it this way because IT IS GOING TO END UP BEING 29.97FPS IN iDVD WHEN I CREATE MY SD DVD PROJECT???? I ask this because of the large amount of time it takes in Compressor converting the footage from 29.97fps to 24fps.
    I can not see any advantage at all in using 24P unless you are planning transferring to film which is 24fps.
    If someone has a different view or I am missing something here could you clarify please? Please keep the explanation simple as I am not a super techie when it comes to these discussions!!
    Frustrated, confused, and need of a simple explanation if I am wrong here.
    Regards,

    No...that is NOT the only advantage. Outputting to DVD is also a serious advantage, as, again, 24fps gets you more storage and better data rates. DVDs you buy with Hollywood movies are all 24fps.
    Then there is the storage used to edit the footage on. 1 hour of Prores at 29.97 is about 76GB, and 1 hour of ProRes at 23.98 is 61 GB. Big savings.
    Also, there are many formats of broadcast HD delivery that require 23.98 masters. I am required to deliver HDCAM masters at 23.98...sometimes HDCAM SR masters. So it is not only for film...
