I would use this for spooling if you can or at least test this. I
would not use raid0 for a system disk but I am going off topic..

Not for 1 single job but you can run a second job on the second tape
drive at the same time. You can also run more jobs on the same tape
drive at the same time and they will keep the tape drive more busy if
you limit the spool size to a few GB.
