I think what he means is that if the OS supports it, the RAID stuff is
done in the BIOS. We don't yet support it, so it has to be done with sof=
tware.
as an aside, I'd suggest vinum over ccd for the software part.
I have two 4 gig drives, and the performance is on par with what =
I've seen from single 8 and even 12 gig drives.
