The HPT370 is (AFAIK) a software raid controller -it's only a little further
on from a standard IDE controller. Like a Promise Fasttrak - they're not
hardware raid either.

No, not snobbery. The fact is you can do IDE raid in software without the
need for one of these cards anyway - I suspect the card makes some things a
bit quicker, but not noticeably. The fact is IDE requires more processor
hand-holding anyway, so you'd basically need a processor on a card if you
wanted to do proper IDE RAID. Which would cost more than a SCSI controller.

Cheers,

Alex.

BTW - I have a Promise Ultra66 myself, which I could easily turn into a IDE
RAID card with the replacement (IIRC) of just one surface-mount cap. I don't
bother because I don't gain anything; Linux has the abilities anyway.
