Mac Pro RAID Handling - Question!

Hi!

Quickie question that I don't seem to be able to grab the answer for on the ol' Internet, if I had four disks in an array in my Mac Pro, each with 16MB of cache - would they all be added together to have a 64MB cache?

The type of RAID will be RAID 10 I believe.

Thanks in advance!

AFAIK they would each have their own cache, don't think it would be totalled and shared if that is what your asking?

The RAID controller has the cache for disk writes/reads.

Yeah that is what I was asking!

Ah, OK - thanks for that! Will look into how much cache the Mac Pro RAID controller has onboard.
