Which is better? 4x Cheetah or 2x Raptor

I currently have 2 Raptors on Raid 0 setup, but I noticed that U160 Cheetahs are about 1/2 the price per drive compared to raptors... I couldnt pinpoint any major difference between the 2 except having 4 Cheetahs will 2x my space, plus I can add more Cheetahs as Time comes, would it be more beneficial to get 4 cheetahs? or even stick it out till SATA II drives start releasing?

Either way, im running Raid 0
 
Which Cheetahs exactly? There are six generations of 10k models and three generations of 15k (so far).
 
Raptors. If the Cheetahs are 1/2 the price of the Raptors, they must be ancient. Old Cheetahs are loud, hot and slow by even today's 7200 RPM ATA drives' standards in the vast majority of home user applications.
 
A lot of people say that when your drives are in raid 0 without data redundance, you double your chance of harddrive failure... well, how often does your harddrive fail?

Ill have to check, but im pretty sure theyre 10k rpm U160 Drives.

Joe: What kind of car did you get, Fred? 😀

Fred: a Ford! 🙂

Joe: cool, what kind of Ford?

Fred: It's red and has four tires! 🙂

Joe: uhhh, that could describe a lot of Fords, Fred 😕 What model of Ford is it?

Fred: it has four tires and it's red! 🙂 Oh! and it has doors, four of them too! 🙂 *nods at Joe as if this could only describe the particular Ford he got*


(hint, there are several generations of Cheetahs that are 10k and U160 😀)

If you're running this setup in a standard 32/33 PCI slot, there is no reason at all to run a 4 drive Cheetah RAID 0 array. The 2 drive Raptor array will already saturate the bus meaning any potential performance gain 4 Cheetah's may have is wasted. If you have onboard SATA that bypasses the PCI bus than the Raptor array will be faster in all facets of performance. The only reason a home user should ever be using RAID is for true RAID (1 or 5 most often) to prevent against hardware failures. RAID 0 is not a real RAID setup and should be left to applications where it is actually beneficial and where the downsides don't come into play.

People say because they are right. All models of hard drives have a fail rate. The manufactures know this and have a good idea of what that rate is. If you do a 4 drive RAID 0, you quadruple your chance of failure. And all of that is very silly, because as everman put it so succinctly, "Raid0 is a waste."

Nice RAID tutorial here.
