Yeah - that's how I have it configured at the moment.  I would just like to
be able to say that in the event of a drive failure there would be as 
little downtime as possible.  Basically just enough time to swap the 
drives... :)

Trouble is, the one drive on a conventional disk controller failing 
would make the system unbootable in that instance.  Bad.
