I've never seen anything go wrong with Linux RAID1 over 6 or so years 
and dozens of machines and I've abused it with things like hot swapping 
SCA drives and rebuilding the replacement, cloning machines by splitting 
the pair and letting both rebuild a new mirror, and using a 3-member set 
with one normally missing for my backuppc archive.  What kind of 
problems have you seen?

The discussion would be more meaningful if you can give examples of the 
problems you have with software raid1 - perhaps there are ways to avoid 
them.  For me, being able to use any single drive on any controller that 
can operate it to recover the data is a big win.  Plus, of course, the 
ability to use external firewire/usb drives as members.
