I've had reliability issues with all of the cards I've tried, poor
drivers (this was a while ago though), and the rarity of battery-backed
IDE cards (PATA not SATA). What's the point of a RAID that can be
corrupted by a single power outage?
Unless you have a need for more than four PATA IDE drives in a RAID set,
and if performance is not a primary concern anyway, I'd always just
use software RAID.
