Are you sure that the FastTrack 100 TX2 is actually software RAID?  If that's
the case, why wouldn't one just put one drive on each of their MB ATA
controllers and run software RAID on the system?

I have a client for whom I'm gathering info on an install on one of these
systems...  'Course, if I go the MB connector-route we'd lose the hot-swap, I
guess.

Hmm, will Linux support the hot-swap, or is that not controlled by the HW
either?
