Ah. We've got some of the older PATA ones here and did the same thing, so
it still seems like software RAID is a better bet.

OTOH I have a couple of 19" chasis that take 16 IDE disks and RAID them to
appear as a large SCSI disk (similar to the 3ware cards), and those work
very well. Big and very loud though.
