That's about the same I get with an AcceleRAID 150 with 16mb and 5 IBM 9GB
7200rpm drives doing RAID5. The RAID controller CPU's just don't seem to
keep up with system processor speedwise. Of course, these are Mylex's
low-end entry level RAID cards. I want to try out an ExtremeRAID and see
if write speed gets much better.
