Is there any circumstance where software RAID supports hot-swap?  For me 
hot-swap is the big win on hardware RAID side, trying to get downtime to 
replace a failed disk is not always easy.

I wouldn't be surprised if Linux software RAID is more reliable, I have seen 
some pretty horrendous bugs in hardware RAID (and heard of worse than I've 
seen).  Usually the problems were on fairly bleeding edge equipment though.

Compaq's SmartArray is one controller that I'm quite comfortable with, haven't 
seen major issues there.
