Any firewire drive that runs at 7200rpm should be ok for DV. You can do it cheap and buy a case, and then buy a bare drive and build it yourself (Very easy). Or pay a little more and get a pre-built one. Either way, make sure you get a case with the Oxford-911 chipset, it can only help. (makes for faster transfers) Oxford-911 is the equiv of a ATA-100 controller, although I've heard it only runs at 40MB/sec Still not bad.
