Did some reading, apparently the Netgear ReadyNAS 2x is smart enough to construct a redundant RAID from non-matched drives, and to rebuild said RAID when a replacement non-matching drive is plugged in. Using only two drives. It is something proprietary to Netgear I think?

So the next thing is, suppose I have my libraries on the NAS device, can TimeMachine on the Mac back up the NAS volume to an external drive? I've only ever used TimeMachine to back up a volume located on the same Mac that TimeMachine is running on.
