I wasn't talking about ripping a drive out during mirroring.  I
was talking about using it purely as a backup drive, as you would
a tape device: mount the drive when you need to, copy the files
you need to it, then umount it when you're done.  Proceed to
safely hotswap drive.

True, but irrelevant for the scenario I'm talking about :).

Yeah, it really does depend on how much capacity you want to back
up.  Hard disks are by far the most cost-effective option for me,
but I'm not everybody (if I were, we'd all be using zsh ;).
