This is true not only for the reliability reason mentioned, but for performance as well. IIRC, only one device per IDE bus can "talk" at a given moment in time.

SATA doesn't have the ability to have primary/secondard devices as IDE does. It's a simple 1:1 port:device ratio, so AFAIK there shouldn't be any "IDE-ish" problems on software RAID sets comprised of SATA devices.
