The {link:VoyagerQ-Dock|http://de.engadget.com/2009/01/07/sata-hdd-dock-voyager-q-erlaubt-fliegenden-plattenwechsel} has SATA, USB and FireWire 400/800. I've running an daily backup in Linux with Bacula. I use the HDD-Dock for Project-Backups/Archiving, Backup-Snapshoots and Data-Transfers.

Eventually - i've not tested - you can use ist with an fast 3,5" HDD on your Notebook's eSATA-Interface. Notebook 2,5" HDD's are slow compared to 3,5" Desktop-HDD's.
