If we're talking true RAID regardless of interface. The only cards that I know
of that work are from ICP and they're SCSI/FC. Also 'very' expensive and last
time I checked don't offer a battery backup. One could make a 'poor mans'
battery backup by keeping the RAM on the controller powered :-) (JEDEC spec is
your friend). It's just a matter of the supporting firmware and drivers being
capable enough to recognize there is data in the buffer and restore it. Though
that's a hack, better to keep everything on a UPS.
