Seagate Technology 200 GB USB 2.0 and FireWire External Drive ( ST3200823A-RK )
Workable, but a bit buggy
The unit was very easy to install and is very quiet.  The upload/download throughput is fast enough for video editing.  The backup utility nearly works as advertised (it seems to hang every so often).  In fact the only issue I've had is a constant (every 30 minutes) and annoying activation of the drive.  It seems to randomly run, without any perceptable reason.
