This is a follow-up with more information that people asked for. Almost
all the I/O will be single process importing, exporting and doing
other operations on a MySQL database. The size we would like is around
.5TB. We currently use 3ware cards with 8 IDE disks using raid 0+1 and
get GREAT performance, but we are now looking for an external solution
with comparable bandwidth. Most companies either don't mention bandwidth
speeds at all, or just quote the maximum for the channel (e.g., 160MB/s
for Ultra160/Ultra3). The program we have been using to do benchmarks
is bonnie++.
