Great thanks for that info Nate, I just checked out their web site, looks like the 9500S-4LP would suit my needs 
for a desktop machine.

I've been leary about desktop RAID cards because a few years ago, I bought an adaptec 1210SA RAID card which supposedly does
RAID 1  I never could get the darn thing to work in my old windows machine and years later found out it is really a fake raid card.  It's been collecting dust ever since
may as well throw it out.  The drivers it required never worked with W2K.

But the Centos server I use has adaptec SCSI RAID controller in it, I guess on the high end for SCSI RAID, adaptec is known for good raid cards, but the one I bought sure did nothing for me
for my desktop.
