RAID 0 with same capacity but diff. buffer cache size?

Just a quick question:

I have two 120GB Seagates, but one only has a 2MB buffer cache and the other one has 8MB.

Question is, can I still RAID 0 these two drives without any issues... or any performance loss that will negate the speed gain from doing a RAID 0 in the first place? Or RAID doesn't give a damn about cache size, the only thing that is important is that they must have identical capacity?

I am running a 100gb and 120gb drive in RAID 0 (200gb array), so they don't need to be the same size...

About the cache, I have no idea. Most people run identical drives so it may be hard to get a definate answer. Just try it and see what happens. It won't hurt anything...

Everything will be of the lesser of the two. If there are different caches it will run as if they both had 2MB caches.

you can raid pretty much any 2 drives. i have even set up a raid stripe with 1 ata 100drive, and one much smaller ata 66 drive. Don't ask me why i did that, it was a temporary solution, but it works. .

i wouldn't worry a bit about it. Slap those suckers in there!


cheers,
