Question about SSD speed rMBP 13" 2015

I think I read somewhere that the 128GB SSD included with the base configuration of the recently refreshed 13" MacBook Pro with Retina Display is slower (in terms of read/write speed) than the other, higher capacity drives that are configurable. Could this possibly be true?

More chips = more paths to read and write from simultaneously, big SSD's are made up of a larger number of smaller chips.

Switching from PC to Mac, have question about processing speed

Hi, I am going to buy a used Mac off of ebay and I am pretty clueless about where to start. I am not very knowledgable when it comes to the difference in processing speeds on pc's and apples both and have just been using what has been passed along. I am on a budget and cannot afford to do a bunch of upgrades when I get a new (to me) apple. I am currently working on a old pc (8 years?) that has had as many upgrades as it can handle. It is a Pentium III 548 mhz, 384 mb of ram and 40g hd on Windows XP. The Apple that I am stuck on getting right now is a G3 with a bunch of upgrades. It is an Imac PowerPC g3 with a 600mhz processor, 512 mb of memory, 120 gb hard drive. It has OS X 10.4 Tiger and ILife and has a single processor. It has a airport extreme card also. My question is 1) Does it take less mhz and ram to run the operating system for an apple and 2) am I going to notice a big difference in speed between what I have now and with the apple? The g3 is $249 and comes with a 90 day guarantee minus shipping. Any help is appreciated, thanks in advance!

I'd save your money or apply it to an Apple G4 (AGP or newer) tower. Depending on how it was configured, you may find that your PIII was a little faster loading web pages than the 600 MHz iMac. My 1 GHz P3s are faster than my iMac DV G3-400 MHz models. I think $249 plus shipping for a 5 or 6 year-old iMac is a bit high. I picked up one of my G3-400 MHz iMac DVs for $20 at a thrift store. If there are any in your area that accept donated computers, you might want to check for a local bargain. While the 600 MHz model that you described is loaded, that's about as far as it goes, other than bumping the memory to 1 GB, but that would likely involve removing a pair of 256 MB DIMMs already in it, and buying a pair of 512 MB DIMMs. If it has a single 512 MB DIMM installed, you wouldn't have to spend as much. Selling the computer with Tiger installed but without the OS installer media will eventually put you in a bind, when you'll need to boot from the installer CD to perform disk repair maintenance. Some may consider Tiger to be a bit demanding of that iMac's system resources, preferring the predecessor "Panther" instead. The bottom line is that the iMac is somewhat limited, in terms of design (no PCI slots) and/or future upgrade potential. If it will suit your needs as a starter Mac, try finding a comparable model for less. You might also check for used computer dealers in your area, as that saves the cost of shipping, and return shipping - if there's a problem. The G4 tower has more potential for hardware tweaking, if you decide to stick with the Mac OS. You can find G4 towers at eBay selling for less than $249, but you'd need to have a monitor. Is space at a premium, in terms of a preference for the iMac's compact form factor? There is a direct correlation between the OS version and the optimal processor speed and amount of installed memory to adequately run it. OS X needs/uses more memory than the older, pre-OS Mac versions, just as Vista or XP2 requires more memory than Windows Me or 98SE. A comparison of Intel's P3s to Apple's G3s or G4s gets into the debate over which one handles more instructions per clock cycle than the other at a given speed. It's difficult to do a head-to-head comparison, because the hardware and software is not the same.

Question about high speed DSL

I have had high speed DSL 1.5 MB service since 8/20. Up until last night I was in love with the service. It was running between 600 and 1000KBPS excededing my expectations.
Then last night around 9:45pm it got extremely slow. I am talking 23.3KBPS on the bandwidth test I was able to run from CNET. I followed the instructions in the tech support and power cycled my modem and PC. I checked all connections and they were secure. The DSL light is solid which from what I have read here means I have a connection.
Would rain/thunderstorms cause an issue? We have had a large amount of rain since Saturday.
I am just frustrated with this issue.
Solved!

Question about transfer speed of my cloud ex2 product. request advice please

Hi guys, I use Raid 1 on my cloud ex2. I have something weird going on. When i received mine My Cloud ex2 with dual wd red of 6tb disks i just unpack all the gear and just do the installation as provided. I used also the data cable that was inluced in the box and i connect it to mine Airport Extreme router from apple. Also mine computer is windows and is also connected on the Airport extreme and if i do a speedtest of mine connection via this website www.speedtest.net. below you see a picture of it. The problem i have with mine My cloud device is i wanted to copy mine files from a wd 4tb external disk wich is connected on my pc via USB 3 connection from there i copy them to mine Wd my cloud ex2 drive via network and i try to move arround 50gigs in total and he write them in aprox 10MB/s thats ridicilous slow speed. How i can solve this issue /? is there any way to do it faster because i also wanted my movies on the nas but if i see that 50 gigs takes me aprox 2 hours to get the job done ya mine USB 3 external disk do this operation much quicker.... pfff I checked also mine network and i have 1Gb speed and the network light at the back of the mycloud ex2 is GREEN blinking because of the copy proces.... Anyone can give me explanation about this matter Thanks in advanceSteve

I beg to differ.....my EX2 was showing 10-11MBps (thats megabytes) until I learned a thing or two about home network infrastructure... What did I learn? 1. I had an old router that did not support gigabit (problem!)2. I had old network cable that was homemade (possibly a problem)3. I had outlandish expectations of my hardware despite #1 and #2 (biggest problem)4. At no point did I doubt the EX2. I was smart enough to know the capabilities of most hardware just didn't know enough about networking hardware. (first step to solution is admitting there's a problem) What did I do? Well I thought about how important it was for me to be able to move data between my PC and the EX2 as fast as possible so i scoured the Internet for answers. I then decided my newer technology devices (iphones, Ipads,Wifi TVs, etc) coud benefit as well from upgraded hardware. So I purchased a gigabit compatible router (it was hard to part with the cash for a stupid box with blinky lights) and a new cat5e cable. BOOM! 60-70 MBps from my PC to and from the EX2. Now, I would like to see even higher speeds being that my SSD can handle nearly a GB per second and being that a gigabit connection (in theory)) is equivelent to 125MB (and i'm aware of some overhead needs) i was hoping for maybe 90-100MB per second. This is acheiveable perhaps with utilizing a gigabit switch instead of the router and guaranteeing no other writing to the source and destination drives but I've got bigger problems.... The wifi to my Laptop is bottlenecking my speeds to the NAS at around 11MBps which I think can be fixed with a new wifi card that is capable of AC speeds. No blame to the EX2 on this...either way despite my less than desirable speeds in the beginning, I never had an issue streaming from the EX2 just backing up data was time consuming. If you value your time and want the speeds that the rest of the world is getting... I suggest the following: 1. Make sure you got a Gigabit router2. Make sure your PC has a gigabit NIC card3. Make sure you've got good Cat5e (at minimum) cables. Got all the above satisfied? You should be flying and happier than a blue haired old lady with a bucket of quarters at a Vegas slot machine. To be clear... I am a cheapskate and don't have the most robust machinery but I did learn WHERE to spend my money to get the best bang for the buck. I recently went on a purchase binge but with a well thought out strategic plan... PC = HP500-314 >>16gb Ram >>250gb Samsung 850 SSD >>AMD A8-7600 CPU (total investment $599)Laptop = Lenovo G50-45 >> 16gb RAM >> 500 gb Samsung 850 SSD >> AMD A8-6140 (total investment $549)Router = Netgear Nighthawk AC1900 (R7000) gigabit router The money I saved on not buying a top of the line Intel I7 PC for roughly $1,200-$1,400 allowed me to build two pretty decent machines (with fast hard drives and more RAM than I can use) and a $200 router (now available for $160) for nearly the same price as one awesome machine that wont reach its potential with what I use them for. All that said I would then have no more moeny for hardware and would be running through my 6 year old crappy router. Moral of the story, don't blame the EX2 until you've had a darn good look at the rest of your hardware and network infrastructure. I believe most of the complaints are stemmed from my same early mistakes. You need to understand gigabit, megabit, and megabyte before you make any claims. Hope this helps someone! Sorry for the long post, I think I just found out how much I like writing on my new laptop!

Question about SSD space? And BootCamp?

Ok, so I installed BootCamp a while ago because I wanted to have a Windows partition and to play games and such on my MacBook Air (2012). The game I wanted to play is relatively large; about 23 GB + or - a few gigs, and I knew that I should include some extra space in there for updates and other stuff. So, I put about 30GB on the partition. When I went on it, there was only like 10GB free!!! So, I kept increasing and increasing until now, I have a like 48.5 GB partition to hold a 23 GB game with only 7.3 GB free. So:
1) Where did all of the rest of the storage space go?!
2) I noticed I think 10 GB or so is in the "Windows" folder. Can I compress this? Will it damage/mess up the Windows Partition? I want to free up some space, but I don't want to break anything.
3) Can I REMOVE a few gigs from the Windows partition, or do I have to start over? If I start over, will I have to redownload my game and all that?
Section 2
I have a 128 GB SSD MacBook Air. I thought that it would be plenty of room. However, I just got a new iPhone, and within a month and a half, I have taken over 2,100 pictures, which takes up numerous GB. So, if I want to back up my iPhone and iPod and all that, I will need a lot of space on my computer. However, I have a Windows partition taking up about 48.5 GB as I remember, so that's about 40% of the entire amount of space on my computer. So, I had a 72 GB portion or so on my Mac side. I thought that this would be enough, but I somehow only have like 28 GB left. If I keep taking pictures, want to back up things, get apps, etc., I would like to free up/add space. So:
1) I know this sounds stupid (I thought I was good with computers and Apple technology, but I just wanted to make sure) ... but is there any way to permanantly add extra SSD space onto my Mac? Because there's the option to upgrade your Mac to like 256 GB which would be awesome, but as far as I know, this is only online, with the more expensive version of the 13" MacBook Air, and I don't know if you can do this with the computer already bought and installed and all that. So, is there any way to add space? Like not free up space, but ADD it?
2) How does the whole Time Machine/ Pass port thing work? If I transferred 10 GB of stuff to Passport or whatever, (1st of all, is it a USB?) if I plugged it in to my computer, could I easily transfer stuff back and forth? Would it take a while?
i) If I had a game on my computer, happened to have Passport or something, and transferred the files to Passport... (this will be a long question) once I plug in the Passport, could I launch the game? Or would I have to transfer the files back to the desktop...
a) Basically, what I'm getting at is... If I had a game's files on Passport / Time Machine / whatever it is called, if I had it plugged in to my computer, would I have to transfer files to the computer to launch/play a game, or could I just play it by putting in thing..
3) If there is a way to increase the space to 256 GB or so, how much would this cost? How long would it take?
I am so sorry about all of my confusing questions, but I just want to ask a bunch at once so I can set things straight in my mind xD
Please help! Thanks so much!

Question about SSD for T61 with Linux.

Hi, I am considering purchasing a T61 with SUSE linux installed. I had a question regarding the customization process for this laptop. The option for adding the 64GB SSD for this laptop is not available when configuring the custom options, but it is available when customizing the Windows version. Will Lenovo give me the option of having the SSD with the Linux configuration?
Thanks for any help in advance.

General Question About Compressor Speed & Newer Macs

Hi,
I am considering buying a PowerMac G5/2.3 dual-processor. I currently have a G4/350 with a 1.2 Ghz Sonnet processor installed. My main intent is to speed up MPEG2 compression for DVDSP 4 at any encoding setting compared with what I have now. I usually leave this computer running overnight to encode without any other apps running. Typical video length is 1-2 hours.
Will I see a significant speed boost with the G5 and a comparable amount of ram or is it a waste of money? DVDSP simulation also looks choppy. Will that smooth out?
BTW, I have no interest in creating a cluster to hand off Compressor tasks, so that path will play no part in my decision. Thanks for any help.
James

You'll see a difference, for sure.
I work on a Dual 1.42 G4 tower but often visit a friend over at a local post house who works on a Dual 2.5 G5. His machine is significantly faster than mine - I'd say about 40% faster. (and yes, I say this having needed to work on Compressor on his machine)
Considering the greater horsepower difference in your scenario, you should be pretty happy.

Two question about running speed in Labiview RT and FPGA

hi All
Right now I am working on a project, which need to be developed on Labview RT and FPGA
Here I have two quick question.
1. Why sampling rates of RTD (9217) module is very slow, it is just aroud 1/sec? even I just tried to run Labview example.
2. We would like to develop another HMI, which can be used for monitoring the program running in CompactRIO. In my project, i want to use network publish varible to implement this function. but the running speed become very slow, when I put these variable into my codes. (Shown in attachment)
Thanks
Regards

Nope, those modes can be selected when using 9217. Drop an I/O property node to your FPGA block diagram and select correct module from the list and you should be able to set conversion time.
Answer to your second question is that your shared variables update only when there's data available from FPGA. This means that if you use high resolution mode (800ms/4ch) they update once every ~800ms. Changing your conversion time to high speed should give you a faster update rate.

2 questions about connection speeds

Hello,
First up: I've been using the same ISP for 3 years now, at the same apartment, and my top download speed has always been 1.5Mbps (roughly 185K/s). For some reason my top download speed "now" is precisely 150K/s, and it's been that way for the past week or so. (And this speed limit affects all my internet-aware apps.)
Is it possible that I've set an OS-wide download limit without realizing it?
Second question: I'm using MenuMeters to determine my connection speed. When using Transmission, a Bit Torrent app, I can also read it's total downloading speed. When MenuMeters tells me that my total download speed is 150K/s, Transmission tells me that it's only downloading at 135K/s.
Trouble is that Transmission is the only app running. And indeed if I pause the downloads, MenuMeters indicates 0K/s (so there are no other internet-using apps running). Since I haven't found any report of speed errors on the Transmission forum, I don't understand this incoherence.
Any ideas?
Thanks
Loa

Hello,
Tom: very close to what MenuMeters was telling. So I guess Transmissions has some bugs.
But that doesn't solve my other problem: why isn't my top speed 185K/s anymore? Can this be on my side, or is it entirely up to my ISP?
Thanks
Loa

Questions about RAM speed.

I'm a bit confused by this, how it relates to CPU speed, FSB speed, double-pumped this, quad-pumped that. I know my RAM is working harder on account of having to up the voltage on it, but I can't work out how or why. The BIOS is about as illuminating as a cellar, the manual doubly so.
I have a Q6600, Corsair Dominator 8500, on an MSI P7N Platinum.
I've got the Q6600 up to three and a bit ghz, had to up some of the voltages to get it stable in Prime95. So far so good, but I don't have a clue what the RAM is actually doing. In both manual and linked modes...no difference. I see that I can set the RAM manually, in both modes, to 1066 or more (1066 is it's rated top frequency), but I'm not sure if that's real speed or a multiplier of something. At the moment it shows in the BIOS:
FSB Clock: 1350
Mem Clock: 800
Adjusted DRAM Frequency: 798
I've changed the timings from 5.5.5.18 to 4.4.4.12
If I change the RAM to 1066 what will happen? Is that actually 4 x 1066, and it'll blow up? 2 x 1066? What is the 798? What actual 'true' RAM speed am I seeing at "800/798"? Why doesn't "Linked" automatically set the RAM speed appropriately per the OC'd CPU speed? What about this "ratio" thing, where I've read that the best is 1:1? Mine is currently at 13:11
What I want is the RAM operating at top speed, regardless of the CPU being OC'd or stock. The required voltage increase seems to suggest it is, but the numbers say otherwise.
Any help/advice/input would be gratefully received. I've read a whole bunch of guides but none of those I've been able to find cover this area in any detail.
Edit: Ok, I've noticed in Everest that the Memory Bus is 398.9, which doubles-up to the 798 in the Adjusted DRAM Frequency field in the BIOS. Eg, 800mhz. So, if my RAM is rated for 1066 I could enter that into the BIOS and see my Memory Bus do 533mhz? I'm assuming that the 4.4.4.12 timings I've achieved have come out of the overhead I'm saving by running the RAM at 800mhz?
If so, which give the greater performance benefit (in games mainly), 4.4.4.12 at 800mhz, or 5.5.5.18 at 1066mhz?

Quote from: AaronYuri on 11-May-08, 21:21:03
No, the memory frequency isn't bottle necked by the FSB. The FSB is just the base for calculating the memory frequency.
Oh well, that doesn't mean much to me. But from what I can gather from the thread you linked there isn't much advantage to running the RAM at 1066 vs 800 anyway, as the performance difference I'd see in games would be negligible.
Thanks Aaron.

Question about ssd Trim in boot camp.

Question about SSD and OS X applications installer

Well I decided to make use of an SSD which is kind of nice.. except.. there are many applications which won't install onto my HDD.. like Microsoft Office. The installer will only let it install onto my SSD.. which isn't going to work. There's not enough room for every app on my SSD. What I'd like to know is what is up with this.. and can I terminalize something or anything to get around this limitation?

Yes, but you first need to erase the drive and be sure it's partitioned properly:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
Now clone:
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4.Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the second drive.
Source means the internal startup drive.

Question about burning speeds

This has happened from new.
As you see from my Mac Pro specs, it's not daft , but when I tell it to burn a DVD or CD at x4
which is my preferred speed (nice and safe) it ignores me and does it at x8-10 varying
Importing CDs into itunes it gets up to x22ish
Does anyone know how to slow it down ?

Well, first of all, importing songs into iTunes is not the same as burning. Burning is a write operation. Importing is a read operation. (From the standpoint of the optical drive).
You can't really control the read-speed of the drive when importing into iTunes although iTunes does automatically control it if there are errors detected.
As for burning, what program are you using? I'm assuming you are using Toast if you know the actual speed at which the disc is being burned at as Finder/Disk Utility do not report this statistic. When you select 4x in toast, is the number bold? If it isn't then it isn't a recommended burning speed for your drive/media and will automatically step up to the next safest level.
Hope this helps!

Question about processor speed

Ok. I used to have an iBook G4 1.2 Ghz. I am considering getting one off of ebay with a 1.07 Ghz processor...if I had 768 RAM last time and had it with the one i am considering buying, would there big a noticeable difference in speed or performance?

Obviously there will be a difference. I'm only basing my judgement on the fact that I own a 1.33Ghz iBook and having used a 1.42Ghz iBook, the only way I'd probably notice any real speed difference was if I ran them side by side. If you're running with 768Mb of RAM, I think the computer will (in your mind) run [virtually] identically.

Question about minimum speeds required for watching movies.

I watch Netflix on my home computer fine (and Hulu) and will occasionally share the screen with my HDTV and it works fine.
With AppleTV, can I expect to be able to rent/watch movies with basic DSL Internet, with speeds up to 1.5 Mbps?
Or do I really need to have faster Internet to consider it?
Thanks!

I would upgrade. You need at least 3mbps for SD content and 5mbps for HD
Netflix degrades quality based on the connection and you will have a long wait if renting through iTunes.
