Re: New 525 install and disk protection

I think the consideration here is the fact that the cache on the base
raid controller for the CPU is only 40mb. If Joel has one of the newer
high performance controllers, they run around 1.5GB of read and write
cache. This config put almost all the disk on that larger controller and
therefore much better dick performance.

Any comments on whether Joel's 16 disk parity set should be split into 2
sets of 8 ?

Two sets would trade off capacity and possibly a minimal performance hit
for extra protection. RAID6 (dual parity) if it were an option, would
be a better choice for a large set.
