The only issue I've had with software raid vs hardware is lockups. A
misbehaving drive on a software raid can bring the IDE bus to a halt. Hardware
cards (should) lock out the bad drive and keep things going.
Beware that many hardware RAID cards aren't, really. See:
Be it thy course to busy giddy minds
With foreign quarrels; that action, hence borne out,
May waste the memory of the former days.
