Yes, controller BIOS. I am using a couple of 4 ports and now one two port
on the 5000 series of cards. Speed is pretty good on RAID0 which I am
using for a news spool and a proxy server. Hopefully there will be some
management software soon. Once thats in place, and things are working OK, I
will try it as a RAID1 device.

same drives on the same machine: Quantun 7200RPM 15gig drives, some simple
numbers...

First is RAID0, second is the same drive on the Intel PIIX4 ATA33
controller by itself.
