Nice looking 'disk array'

I believe so, yes.  There are ways to instruct a software RAID array
to run in "degraded mode" (can't remember how, offhand--maybe with
mdadm?).  So, supposing your hardware supports hot-swapping, you can
turn-off the target disk in software, hot-swap according to your
hardware's protocol, and then turn the target, swapped disk back on.
Once the swap is complete, the RAID array will start rebuilding in the
background.
