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.
