Hi, I'm new to building computers and I'm working on an i7 build. I have a 1TB Caviar Black, and I was thinking about having a separate drive just for the OS and programs, and then I read about RAID0. So I was wondering, would it be a smart idea to have two 74gb Raptors in RAID0 for my OS and programs and use the 1TB for all data and files and such? Or is that a risky idea? Any input is greatly appreciated!

Most using RAID 0 do so first to put OS on it as first priority. Two Raptors - or the faster Velociraptors would fly in RAID 0 - and maybe be a bit noisy.

On my next build I plan to go with SSD - which I think will be faster and much more efficient - and cetainly whisper quiet since there are no moving parts.

Please see my other post today about SSD - it is the second post on this thread

You might like to communicate on his thread since he is in a similar position - although as an update rather than a new build but is considering SSD v RAID.

So you're saying that one SSD for my os and apps would be faster than two raptors on raid0? The price is definitely an issue for me, I don't know if I could fit an extra 300 into my budget at this point. But what about the writing speed of SSD?

This review presents the best information I know of about SSD vs, other drives.

This THG review from May 2008 has some interesting and perhaps helpful data – although it does not include the Intel SSD which beats the others hands down – and even the others have improved substantially since then. Also the prices are way out of date.

Beyond that you can try to compare performance on the THG hard drive charts, but HDs, HDs in RAID, and SSD drives are on separate charts.
