You'll need a script to re-add the disk into the array to start the sync, and yank it from the array before being unplugged, which is of course easily do-able with "mdadm". Of course as soon as you add the disk back into the array you're going to cause a boatload of IO as the array resyncs from the internal disks back out to the external one, and that's going to happen _every_ time you plug the disk(s) in.
