Advice about SSD on Arch

Im seriously considering to buy a SSD drive for my system.....
I currently have a config like this:
320 Gb SATAII ->> Arch root + windows 7 (for gaming)
2 Tb SATAII ->> /home + Movies
2 Tb SATAII ->> Series and stuff
Im thinking about replacing the 320 one for a single 16Gb SSD just for the system.....
Which are your experiences with this kind of disks?
Are 16Gb enough? (I dont want to spend much money)
Do you recommend me any shop? (That ships worldwide, to spain for being more specific)
When I buy a disk, which things do i have to keep in mind?
Thanks!!!

Is there are really need for that? Even cheap and small SSDs have TRIM-support (like mine) and it's virtually impossible to run out of write-cycles (or what ever is used for mesuring the endurance of the drive) in less than five-ten years (with modern SSDs that is). One shouldn't keep the drive full in any case (were it SSD or HDD, I personally probably haven't ever even went over 50% in usage with SSD) so that really isn't a problem. I haven't noticed any performance degration either. I bet that there aren't many expecting the SSD you buy for 40-50€ to be "everlasting", in the same way that probably no knowledgeable persons excpect HDDs to last more than 4 years safely. If there really is a problem, what's it precisely? Of course the more expensive and bigger drivers are better but is it worth it to pay more for something you probably never benefirt from, added performance isn't exactly useful if the bottleneck is somewhere else.

Please advice about fast reading/writing

Hi All,
I am building a custom system for Photoshop CS6 and Lightroom 4, I know this is not a PS forum but I think the hardware experts are here.
The components I have already selected are:
i7-3930k
ASUS P9X79 PRO
64GB RAM (GSKILL)
WD Caviar Black 1TB
Since I have enough RAM the scratch disk is not something to worry about, after reading this article about SSDs for PS:
http://helpx.adobe.com/photoshop/kb/optimize-performance-photoshop-cs4-cs5.html#main_Solid _state_disks
I think a SSD is useful only when starting the applications (having them in the SSD), which is not important for me (I do it twice or three times per day). What I would like to do (and is the matter of this post) is to open and save my large pictures (700MB to 1+ GB) as kickly as posibble, is the Caviar Black a good choice or should I consider a SSD? What about a WD velociraptor? Also, I would appreciate advice about other options.
The last custom build I did was probably 8 years ago so I am not up to date with the hardware technology, I have learned a lot reading this great forum :-).
Thank you,
William Gonzales

William,
I use Photoshop CS5 and Bridge a lot and care particularly about how fast the PC can read since this dramatically impacts how fast you can process and rank lots of shots.
Bottom line...
Suggest in addition to whatever your boot drive is you configure a 2xRAID 0 7200rpm drive setup for your data. You have an extremely capable CPU and lots of RAM, so your disk speed is definitely a bottleneck.
Another alternative, although more expensive and quite a bit smaller would be one of the latest, fastest SSDs that can finally deliver on the write side. (i.e. Samsung 840 Pro and its competitors). This would be a secondary drive to whatever you have for your boot drive.
Another suggestion, is make sure you have a video card with good 2D speed. That is get one that can move lots of data; this spec. (Memory Bandwidth, often in GB/sec) is often buried since gaming and 3D features (cores, shading, memory size, etc.) are most important for most users. My video card, a GTX 480 has a memory bandwidth of 177.4 GB/sec, but probably any card with at least 80 GB/sec will probably work very well with your apps.

Jim

Advice about buying a new hard drive

I have a TOSHIBA Satellite L25-S1216. I have not been able to boot into Windows XP for 3 years using the factory Recovery and Applications/Drivers DVD and the Fully Recover procedure on the back of the DVD packae. I have been using Linux for the past 3 years. Ubuntu SMART test disk utility tells me I have 20 bad hard drive sectors. I have concluded I should buy a new hard drive, since mine has 20 bad sectors. My current hard drive is ATA-6, so I know I need a PATA compatible hard drive. I'd like to increase to maybe 60 GB from the current 40 GB. I'd also like to go with a solid state drive, but there don't appear to be many PATA compatible solid state drives.
And I don't want to get too complicated or expensive; I want to stay with my current Windows XP. Not sure if a SATA PATA interface adapter would work to allow me to use a SATA solid state hard drive or not. I know (from reading knowledge base posts) there is also the potential problem of the older BIOSs not recognizing the newer Advanced Drive Format drives.
QUESTION: Does anybody have any advice about buying a hard drive that would work for me? How can I be reasonably sure a hard drive I buy is compatible with my computer?
Thank you,
Bob
Solved!
Go to Solution.

either get a pata drive (you can get larger than the stock 40gb) or use your $ towards a more current new/used laptop. pata ssd would be a waste and I doubt adapter would work. also, ms is dropping support for xp so it would be a good time to upgrade to something with a more current os as well.

Expert advice on SSD performance bottleneck needed.

Masters of storage, please step forward...
I guess I need some technically advanced advice on SSD, SATA, in/out limits etc.
I'm programming a video installation where I continously read and write quite a lot of data:
To the first SSD, drive A, I write 50 frames per second (= 50 files per second) plus simultaneously read some other 50 fps (from the same drive!).
From a second SSD, drive B, I read an additional 50 frames per second.
The question is: Where is the bottle neck? I succeed running my program at 25 fps but not faster (and i would need to get it to 50 fps).
The total amount of data is actually not that excessive: Each frame is 1,8 MB so each stream is about 90 MB/s which comes down to a total of 180 MB/s read plus another 90 MB/s write = 270 MB/s total data transfer in 150 read/write operations per second.
What confuses me most is the following:
- I get the same performance when I run the patch from two separate SSDs as when I run all three streams from a single one without using the second SSD at all.
- The speed does not increase substantially if I make one or two of these streams smaller (and reduce the file size to 260 KB/file which equals only 13 MB/s per stream).
- It does increase however (to 40-60 fps) if I switch all three streams to 260 KB/file.
This makes me wonder what is going on... is it the drives? Is it SATA? Or some other stuff I maybe even never heard of? And what can I do about it?
I use a Macbook Pro (Retina, early 2013, i7 2,6 GHz, 16 GB RAM, OS 10.9.2), drive A is a Samsung 840 pro 256 GB SSD connected via thunderbolt, drive B is the internal 512 GB Macbook SSD (built-in from Apple).
My program is built in MAX/MSP and I use a an arbitrary, uncompressed binary data format (.jxf). I can rule out CPU-/GPU-load issues.
Thanks for any help, it is appreciated a lot!

I'll pass this along because it seems to make sense. I only discovered noatime myself today and set it up using these instructions; it doesn't seem to break anything so far and should speed things up some as well as reduce wear. There's also mention of Chameleon which can activate TRIM but also turn noatime on. There's a discussion of atime and noatime here. Note that there's mention of relatime replacing atime as default though what the upside and downside of the variations are is above my paygrade.
If you're going to tinker with .plists, I'd suggest using TextWrangler.

Advice about using the laptop with closed lid while connected to external display

Hello all HP forum members!
I have an ENVY 17 with Win8.1 64bit, a great laptop, but I need an advice about using it while connected via HDMI cable to an external display (TV).
When I play heavy 3D games, the computer produces more heat than usual (of course this is normal), but doing so with closed lid, could this harm the display in some way, as a result of the heat?
Thanks!

Hi @VVel ,
Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP ENVY 17 Notebook and issue with keeping the Notebook on while closing the lid. Here is a document on changing the Power option.
Control Panel - Power Options - upper left - Choose what closing the lid does.
Change Plan Settings and also check Advanced Settings. Make sure you do this for both battery and power.
Hope this helps.
Thanks.

Need advice about a WiFi set-up

Dear Gang,
I want to have a pure 802.11n network using the 5 ghz spectrum and the wide array setting. However, I have one desktop computer that is 802.11g. I'd like to run a 25 ft. Cat 5 cable to one of the LAN ports on the TimeCapsule and then shut-off the WiFi on this computer. However, strangely enough, I've always had all my computers (even desktops) networked via WiFi so I don't know how well using the LAN works.
What are the thoughts of the group?
I know that ethernet should give me greater speeds to the TC's hard drive and should solve my problem with bringing a non-802.11n machine in to a "pure" network, but I don't want to do so if the set-up is arduous or if doing so makes me lose a lot of features that I get in an all WiFi network.
TIA,
Mark

dwb,
I'll definitely take your advice about the ethernet cables - thank you.
Your info is reassuring as it means that my dual G5 will get a little more life out of it by connecting it in to my "pure" system via ethernet.
Two other quick questions:
-should I connect my new iMac via ethernet to the router, too, even though it's capable of going on my system in 802.11n 5ghz?
-also, as an aside, I'm trying to figure out if my new 802.11n network will equal my current 802.11g network in terms of distance as I have an Apple TV that's a few rooms over. That Apple TV gets about 4 bars of signal from my current network. Do you think that 802.11n at 5 ghz will have an equivocal range?

Need advice about zip rar files

Here's wishing you all a very happy New Year!! Mr Greenhorn is back again! I have a question about zip and rar files. As some of you may remember, this is my first Mac, so I'm used to using the zip/rar programme on my old Windows O/S. Now I receive zip/rar files and can't open them. What is anyone's advice about downloading the zip/rar programme onto my Mac? Any particular pro's and con's? Any particular site to download from? Now my Mac has a compression programme included which converts files to zip files, but is that compatible to the actual zip/rar programme? And finally, where is the advantage to compressing files? Is it only for uploading or is there some benefit to having files 'compressed' on your actual laptop?

Hi There
Mac OS X has a built in Archive Utility which doesn't support .rar files. To uncompress rar files you will need a utility like RAR Expander or Stuffit Expander both are free. I suggest doing a search on MacUpdate (http://www.macupdate.com) or VersionTracker (http://www.versiontracker.com) to find a programme that you like.
I personally don't see any advantage with keeping compressed files on your laptop (unless the archives being used often for emailing, uploading to websites etc). Compressing files does save disk space but if you get to the point where you need to compress your files to gain disk space then I suggest buying an external HD or a bigger internal HD.
Hope this helps

Need advice about coalesce and deallocate unused space

Hi experts;
Here looking for an advice about coalesce and deallocate unused space.
I got this tablespace with 87% full, one of the table in that tablespace has 1,150,325 records. I'm going to delete 500,000 records from that table, but to release the space used by those records I understand that I need to execute other procedure. I was reading about coalesce tablespace and deallocate unused space.
I found that apparently, both process can help me to free space. If you want to share with me your comments, about advantages or disadvantages about them, in order I can take the best solution?
Thanks for your comments.

Hi
after deleted rows, the high water mark is still the same and so the size of the table. you need to bring down the water mark
here is what you need to do to bring down the high water mark. We do this monthly for performance purpose.
This is an EBS R12 system but the procedures are the same for EBS database or non EBS database.
After you purge or delete data in a table
1) alter table APPLSYS.WF_ITEM_ATTRIBUTE_VALUES move; <-- this operation will invalidate all indexes attache to the table
2)select owner, index_name, status from dba_indexes -- list all invalid object for user APPLSYS
where table_owner = upper('APPLSYS')
and
status NOT IN ('VALID','N/A');
3)spool idxrebuild.sql --generate script to rebuild indexes.
select 'alter index ' ||owner||'.'||index_name ||' rebuild online;' from dba_indexes
where table_owner = upper('APPLSYS')
and
status <> 'VALID';
4) run idxrebuild.sql -- to rebuild indexes. -- at this point if you check spaces on the table, it is still the same, you need to run #5
5)exec fnd_stats.gather_schema_stats ('APPLSYS'); --fnd_stat is for EBS system you can replace with the database equivalent command.
use this statement to count the block before and after the operation to see the different.
select DISTINCT(SEGMENT_NAME), count(blocks) "Total Block" from dba_extents
where
owner IN ('APPLSYS')
AND segment_name = 'WF_ITEM_ATTRIBUTE_VALUES'
Hope this help.

Need advice about transfering files

Hello. I just got a new mac through an education deal at school. I hate this process of transferring files from one computer to the next but have never done it from one Mac to another before so thought it would be pretty smooth. Im new to the whole Migration Assistant and so need some advice about what to do next.
I tried using migration assistance upon first turning on my new mac but was using wireless and it just wasnt working. My computer kept saying my new mac wasnt responding and I kept having to select ok or cancel every minute and with 15 hours to go, i thought f^*# it. So I decided to just start the computer up and manually transfer files. Then I found an ethernet cable, turned file sharing on and am using my public folder to transfer but its turning into The Most Tedious task and things arent transferring properly (like certain folders arent copying contents, just the folder itself).
Now Im wishing I could have used migration assistant from the start but what can you do. I cant just re-install the mac os software and try again because before we got our new macs they installed some programs for us, like Logic, and I dont really wanna mess with that.
Whats my best option at this stage? Ive transferred about a gig of pictures and documents over so far (and I think my old hard drive is about 60 gig full) but theres a bunch of other little things like iphoto, imovie, garageband, stickies, as well as big folders of music (and itunes - playlists etc) that I wanna make sure get copied in entirety. Will migration assistant handle that? Is it best to delete the stuff Ive transferred so far and let it start fresh? What would you do?
Sorry my post is so long
Message was edited by: girrrl

Also, now that I have an ethernet cable, if I go ahead and use migration assistant to transfer the account from my old computer, will Logic only be available through the new account I have set up on my new computer? Would I have to log out of one account and into the other and back and forth to access the different files/programs? Any help would be much appreciated

Need advice about making a application log over every task succsessfully done to a target

Hi!!!
I need an advice about how to make an application log over every task succsessfully done to a target with an unique ID.
I have developed an application with several tasks on the menu which have to be done in a certain order to program and test a target board,
and the user want a log about which tasks are done to the target, so it is easy to know which step is next on the menu (It is a very routinebased job).
Do somebody have any good advice on how this can be done in a cleaver way ?
Best regards,
A

Advice about buying new Macbook

Hi all,
I'm trying to decide between the Macbook Air and the Macbook Pro with Retina display, and I'd like to see if people have advice about which one would better serve my needs.
This is my only computer, and while it needs to be portable, it doesn't need to necessarily be the lightest possible (Macbook Air).
What I do want is at least 256GB of storage. Right now I have 156GB, and I'm almost maxing it out. I've had to take things off my hard drive to make more room. I have a large iTunes library and a large iPhoto library, and I want all those things on my hard drive.
I also want good performance because that's where my 2008 Macbook is not doing so well - gets very slow, esp when iPhoto and similar apps are open.
I need to be able to work with several apps open - Word, Excel, Adobe Reader, Chrome, etc. I don't need to do a lot of gaming or sophisticated video editing or anything like that - I work mostly with MS Office programs.
So is the Macbook Air good enough or should I get the Macbook Pro?
Thanks!

The Air should be ample for your described needs. If weight is not a consideration, the Air has by far the best battery run time, so if a lot of work is done without an AC outlet available, that is some thing to take into account.
The Pro has a superior display and is a more powerful machine, but the extra power is not needed for what you have described.
Personally I would urge you to consider installing as much storage as you can afford. Using external HDDs in the field gets very old quickly. Over time data has a habit of increasing.
One important point to keep in mind, with both the Air and the Pro, no future upgrades are available at this time so configure the unit accordingly. I would spend my money for upgrades in this order, storage, RAM, CPU.
Ciao.

I agree with LowLister, the best option for you to share the video online is to upload it to your online storage account for example : Box, Dropbox, SkyDrive (All of them provide free storage beginning from 2GB).
You can upload the files which you want to share in this online storage and then they have sharing options in which you'll will get the link of the file to be sent and send the email. You're good to go!
Tip : You can store multiple files for backup purposes.
