For performance, which is better in a RAID-0 scenario :
A) 2 x SATA I 10k rpm Hard drive
or
B) 2 x SATA II (3G) 7.2k rpm Hard drive?

More about : sata 10k sata

the seagate 7200.10 will outperform a raptor in almost every category execpt seek times. you also get 2-4x the space? if cost is not a problem, RAID0 150gb Raptors with a seagate 320gb 7200.10 for backup would give you great performance and security.

Since SATA II does not make ANY real difference, go with the 2x 10K drives, since the 10,000 RPM drives will make a difference.

I've never owned any Raptors (definitely planning on buying a few of them for my next build, though), but I'm pretty sure two 36.7GB Raptors in RAID 0 gives the fastest bootup times any HDD's out there can offer, followed closely by any other RAID 0 Raptor setup.

I have a single 36.7 Gb Raptor for my OSes and programs, and it flies. You can tell the difference with the access times for your OS.

Seek times are more important than you might think. My advice if money isn't really a factor is to RAID a pair of Raptors. If this is not an option, get a single Raptor for Windows and apps, and a Seagate 7200.10 for all your files.

Completely wrong.

Tt has been said hundred of times:
1. SATA2 is not faster than SATA1, it's an extension of the protocol standard only
2. SATA2 doesn't automatically mean 3Gbps: HD and CTRL running at 3Gbps are marked SATAx-300 not simply SATA2.
3. the faster SATA drive available is the Raptor WD1500Axxx with sustained trasnfer rate of 80MB/s, very slower than the maximum effective bandwidth of SATA1-150 (130MB/s).

Please read THG benchmarks and SATA specification whitepapers before speaking.

The new Seagate 7200.10's can READ almost a full MBps faster than a Raptor...so useing them would be faster to load things than useing Raptors.

Alot cheaper also and they come in 200GB-750GB sizes.
Newegg had the 200GB size for $104 and you can expect the prices to drop as time goes on.

no the 36.7 gig raptors wern't the fastest raptors. Check some benchmarks.

The Raptor is faster overall, the SATA standard is irrelevant as it makes little difference.

Go have a look on Toms Hardware Storage section - there's an article benchmarking the new 7200.10 drives, and also the interactive disk chart. The newest Raptor wins in virtually everything - but they are much more expensive per GB - you pays yer money ...

If you do get a 7200 disk, make sure you do get a 7200.10 (as zolddude says), as this uses the new perpendicular recording technology which means higher aereal density and is therefore pretty damn fast.

LISTEN!!! Whichever drive has more cache get, that is the biggest factor in performance.

And obivously if they are the same cache the faster drive has better performance duh.

sorry this is so late but i just had to point this out as everyone knows here for the most part but just to sort out any confusion, a raid 0 setup will NOT give you any security as it is not redundant...a raid 1 setup will give you security with less speed

I think that you are missunderstanding him. I believe he is talking about a RAID 0 Array backed up by a Seagate 320 GB 7200.10. Done properly, this would give you a measure of security, using ICE Mirror or some other simialr tool.
