does more cache on HDD's help increase RAID 0 performance?

[AmongTheChosenX]

For instance, the WD6400AAKS versus the WD6401AALS...

theyre basically the same drive but ones got 32MB's of cache (the AALS), and the AAKS has 16MB's.

if they were in RAID 0, would the extra cache help increase performance?

because I'm thinking about selling my 6400AAKS and buying to 6401AALS drives.

Plus i like the warranty. 5 years is nice.

The performance to the loss of money in swapping drives, not to mention the trouble will not be worth it. Instead, why don't you sell both those drives and get a vraptor?

16 MB seems to be the point of diminishing returns for onboard cache for hard drives. Yea, in theory 32 MB may be a little faster, but don't spend extra money just to get the extra cache. It ain't worth the effort.

alright well i'm jsut trying to try and not buy into "old" technology if you know what I mean.

I currently only have 1 WD6400AAKS, so its not like I'd have to sell 2 of them.

I dont need/cannot afford a velociraptor. I'm making a 3 x 36GB 16MB cache RAID 0 array for vista 64 and main system apps, and then going to use a RAID 0 array of 2 x WD6401AALS drives (or WD6400AAKS, depends on what i end up buying).
then a 1TB to backup images of the drive arrays.

I'd buy into newer technology. Especially if you can get a good deal.


The Velociraptors are overpriced IMO.

You can always use your AAKS hdd for storage.
