Whoops, I should add that if your raid 1+0 is done with master/slaves
it could take the hit there.   A Raid 0 (stripe) done to 2 drives, both
masters, would be happy but that's not redundant.   A raid where you
stripe over controllers and mirror over slaves would be slower on write
that having 4 dedicated controllers, but presumably just as fast on read.

As for one drive locking out the other one, if you fear that, then
this is not for you, but you're not trying to build servers for ebay
here, it's a tv recorder.  For me, I can handle if the system hangs
as long as I can recover all my data after I attend to it.
