The driver problems with promise were mentioned, and the 3ware probably is overkill. Have you thought about using software RAID? Yes, it uses a bit more CPU and doubles the PCI bus load, compared with the 3ware (dunno about Promise - I'm not sure if it does RAID1 in hardware). (Of course, if you don't have enough on-board IDE slots free, go ahead and buy 3ware or ICP controllers. Both are reported to have good drivers and work well). > Say, what's the difference between a 32-bit/66MHz and a 64-bit/66MHz > PCI card?

Careful: while technically, the 64bit cards should work, check your board: some boards have some components placed where you would need space for the 64 bit part of the PCI connector. cheers -- vbi -- featured link: http://fortytwo.ch/gpg/intro
