Trying to improve HD/storage performance or something else?

Hi all,
There isn't an actual topic area of HD performance or storage tweaking etc in general so I figured I would post here.

My issue is this: I tend to do many things at once on my computer and in that regard they are, what I assume, very hardrive/read/write intensive, if I can use that expression.
For my work, I will be at any time encoding or decoding video in the background, but at the same time also maybe editing some HTML, couple of instances of firefox open, email and at least 3 or 4 files which are getting rared/unrared in the background for storage or burning and maybe other stuff like file integrity checks using quickpar. I use WinXp and Xp64, have 4 GB of RAM.

I went from an AMD64 3000 to X2-3800 to then an X2-4800 and then an e6600 to an e6850 to a Q6600. Even with the quad core, the system totally chugs I am dealing with a few 2 GB files, and encoding in the background and running quickpar.

I have 2 x 500GB drives, and 1 x terabyte drive (all SATA). The OS is on one of the 500 GB drive. The files I work on are all on the other 500GB drive and I usually do all the decoding, work, compressing etc to the same drive. I then move what is complete for burning or storage to the 1 TB drive for others that might need to access.

Is this inefficient? Is there a better setup? RAID maybe or would I still be stuck with the issue that I am reading and writing to the same drive in multiple instances with huge files? I would love to hear some suggestions? I mean at any time I can stop the 4 of 5 things I am doing and just run one.. and it screams fast.. then as it?s done I do another. Heck by doing this I am actually faster than waiting for 5 things to finish.

Disk performance is your problem as you have already guessed. What are the 500GB drives you have? Seagate, Western Digital, Maxtor, Hitachi? Same goes with the 1TB disk, Seagate, Western Digital, or Hitachi? What are the model numbers as well (if you know)?

For parallel jobs like that, you should be using something like the Seagate Barracuda ES.2, or Western Digital RE2 WD5000YS. These drives are designed with multi-process accesses, re-ordering disk access requests on the fly internally to produce the fastest overall thru-put (at least for SATA drives). RAID "might" help, but in your situation, there is no RAID version that will help you without getting more disks. RAID 0 does not make as large as an improvement in multi-process access as shown in many articles, including one here on Anandtech a while back http://www.anandtech.com/stora...howdoc.aspx?i=2969&p=8

Truthfully, if you need this kind of performance, you should look into a SCSI controller card and a few SCSI drives. Even compare the WD Raptor I/O's per sec in multi-user operation (which is essentially what you are doing when you have that many different applications/processes running at the same time).

Raptor Performance:

Seagate Cheetah 15K.5 SCSI Performance:

Notice that the Cheetah is almost double the performance of the Raptor. It also costs more than double for the drive alone (but has double the storage, so in the end it is not a bad deal, but you also need the controller, which will cost as much as one of the drives...).

First of all thank you for all your info. The 2 500GB drives are both WD 500 WD5000AAKS SATA and the other is the new WD green 1TB.

It seems I do not have the best ones for what I want to do LOL as you noted... at the time I simply (or our company) purchased the best bang for the buck in regards to 500GB drives.

I read the newer 750 GB dries from WD are very good and fast and might suit my needs better. I agree as well from the links you provided that the raptors, although fast as all heck do little compared to the SCSI when tested in that way.

One last question... should I enable then NCQ for my purpose? Is this by default enabled in say my 775 boards (one 680i eVGA and other is Asus P5K-e WiFi)? I never bothered to check within the hardware area where my disk controllers are detailed if NCQ is enabled. I would presume this feature might actually help multi access to my drives.

Thank you for your help. Might have to hit the old SCSI train then.
