I see some reviews and articles about comparing SATA II to the Raptors, but I couldn't find anything on SATA II in RAID 0 vs. a 74gb Raptor in RAID 0

Does the extra bandwidth in SATA II in RAID 0 out perform the pure speed in the Raptor RAID 0?

I would think the rpms alone beat all. to my knowledge a single raptor beats any sataII drive out there. and if thats true then you're basically questioning whether the raptors in raid0 hit the bandwidth ceiling of the sata spec, which i doubt.

http://www.experts-exchange.com/Storage/Q_21330145.html might have some good info for you.

"Hard drives still face physical limits for the mechanical portion of the drive. Improving the interface can help (features like NCQ) but the underlying mechanics are still the same. Changing the drives RPM speed changes those mechanics directly and translates to the gains you see with a Raptor"

and yeah, after reading through that article above two raptors don't even approach the limit of sataI, but four might.

to me raising the bandwidth limits of hard drive controllers means shit until they can improve disk drive technology to the point where we can actually use that bandwidth. the hard drive remains by far the largest bottleneck in a computer.

general RAID question, i have two hitachi 160gb SATA hard drives i would like to run in RAID 0 or 1, but the model numbers differ slightly, they are exactly the same drive except for one has SATAII and one does not, unfortunatly CompUSA sells both under the same SKU#, I was wondering if I needed the same exact model# or not.

i just got a raptor 74gb this week too

shit if they were both SATA I's or both SATA II's then the hds can be different. But I am not sure if you can RAID an SATA I and SATA II together.....I doubt it but I am not absolutely sure

well the SATA II is compatible with SATAI

1/7/2006 10:39:37 PM

If II is backwards compatible, then yeah you should be able to RAID them together even though they are different models


Also just found a review of the new 150gb Raptor....according to the review it out performs 74gb Raptors in 2x RAID 0 and 4x RAID 0. Now thats pretty nasty

come to find out my controller is only SATAI anyways, so i'm guessing it'll be fine

the raptor 150's are already out for ~$296 or so... got my 74gb for ~$135 AR couldn't swing the extra
