he still ought to look at them, cheaper faster disk arrays are nothing
to sneeze at.

SCSI is only a win these days if your running the most expensive 10K
RPM drives in a mirrored configuration, which is common on database
servers.  And raid-5 in particular unless you have a minimum of 5 drives
in your array, you are going to just be throwing the performance edge
of the more expensive scsi drives into the toilet, so what is the point of
buying them?

If your doing raid 5 for redundancy, there's no argument, sata is the
clear winner on the 3ware or highpoint cards.
