I would agree with Justin.  I have a DSSU of around 8TB sitting on a
CX600, with 15k drives in a SAN, and even with that the staging off will
slow down the backups enough to add around 6 hours to normally a 20 hour
backup.

You CAN do it, but you can also drag a 1000lb weight behind your car...
but don't expect to get good MPG!  ;-)

Why not reserve a drive for restores?

I wouldn't recommend both unless you had a SAN beind it or a lot of 15k
drives.
