I don't know the specifics of those cards, but if they include an i/o
processor, they are a hardware RAID.
Keep in mind that unless you want to boot or use a RAID 5, or want to
share your RAID volumes between different operating systems, there is
little reason to purchase a hardware RAID card. Software RAID is quite
sufficient for most needs and the host processor running at 2+ ghz is
much better at RAID then a 60 mhz i960 IOP. Keep in mind, though, that
hardware RAID adaptors have built in xor accelerators which can do
multiple xors in one instruction in hardware, allowing for much better
xor performance then the intel or ppc processor can do.
Thanks
