Good, choice. This should make a pretty large difference in performance and

in some cases a factor of 2~3. I get 170MB/sec reads and 80MB/sec writes on
a 6 disk raid 10.
These are 15K rpm disks though, the 10K rpm disks should have a higher
sustained transfer rate.
This is based on a Perc4/Di which is onboard a PE2600. The add-in boards
are a newer generation Perc4 controller and the Perc4/Di which is onboard
the 1750 is the newest afaik.
They have one thing in common though, they perform a _lot_ better.
I don't make sense, I don't pretend to either. Questions?
