NBD is fast but has one problem: if you lose network connectivity for a 
while (tcp drops) there is no recovery I am aware of. I think it unmaps 
the disk until user intervention. Or this was the situation a couple of 
years ago.
Actually for RAID this might even be a good point, but keep it in mind.
iscsi seems an obvious alternative. And you can put anything under MD I 
think, but DRBD (without MD) is probably better because it's made 
exactly for that purpose.
