yea i def want to upgrade to ssd, at the time a built the computer it was just more affordable to get the raptors, i needed atleast 200gb for my os drive.

any recommendations as to a cost effective ssd thats around 200gb?

I take it your drive "C" is is your RAIDed Raptors? I notice that your random reads and writes are a good bit higher on your Raptors over the Barracudas - that's an important hard drive metric that people often overlook. For daily tasks when opening and running multiple programs, you'll see a better speed boost with an increase in random reads over sequential reads because the programs are scattered about your drive.

Although, loading levels in games probably benefits from a higher sequential read.

Also, I've heard that faster spindle speed drives can have a little more trouble reading from the platters simply because they're moving so fast. The faster speed helps the drive find things better (ie, faster random write/read and access time), but makes it harder for the heads to actually read something from the disk (ie, slower sequentials).

I might not have described it right, but these are just some things I've heard that may help explain what you're seeing.

Also, you could consider "short stroking" your Raptors, by formatting only the first third or quarter of your Raptors to limit them to the outside edge of the hard drive platters. This will not make your drives any faster, but it will eliminate the slower speeds you see as the drive begins to access the inner part of the disk, so your average speeds will increase.

will i lose space by "short stroking"?
and yea c: are my raptors

-ps thanks for all the quick responses

Yes, you will lose space, and you said that your Raptors are about half-full, so it might not be a good option for you.

You can format the rest of the space as a slower partition however. So you could separate the drive into a games partition and a "regular programs" partition if you want.

Here's some more info: http://www.overclock.net/hard-drives...e-why-how.html

Just remember that its not making the drives work any faster, just that you're trying to keep all your programs and files confined to the outer portion of the platter where read times are faster.

The Cruical M4 is the best SSD on the market in my opinion, and it has some of the best prices too.



It's still going to be a lot of money though. I'm going to be getting one for my next build.

cool ill look into it, i actually install all my programs and os on the raptors, and i install my games to the barracudas, so i think thats the most efficient ill get out my current setup i guess.

is it cool to run ssds in raid? it prolly wont make any difference in performance, but will it hurt performance? im thinking i might be able to find two smaller ssds cheaper than one big one

Don't put SSDs in RAID, you will lose TRIM which will dramatically hurt performance overtime. Just get the 256GB, it will be best option.

If I was you I would put open world games (WoW, Oblivion, Fallout, etc) on the SSD and linear games on the raptors assuming it won't all fit on 256GB. OS and all programs should go on the SSD of course. Open world games tend to benefit greatly from SSDs due to 0ms random access.

Also note that unless your motherboard has SATA3, you won't get the full speeds.

Raptors should usually be 32K stripes. 64K with the newest 450/600GB models. Raptors have much lower access times, so larger stripes actually impair their performance. 128K stripes could cause reads to take ~1ms longer, which is huge on a drive with 7-9ms access times.

7200RPM drives tend to have higher sequential speeds and higher access times, so 128K stripes don't matter as much. If anything, they play to the drive's strengths. Due to the drive's sequential performance, that barely increases access times by 0.5ms, which is nothing on a 13-18ms seek.


FYI, screenshots tell us more than the text you posted. Graphs, model numbers, etc. reveal a lot.
