Re: SATA Controller

["Jim Buttafuoco" <jim@contactbda.com>]

I got the 3ware card to do hardware raid at first.  The performance we really bad, so I switched to software raid and 
while the performance was alot better, it still didn't match other systems I have here that were doing software raid 
with older IDT (parallel) disks.
