Spec Me Portable Hard Drives (for MBP)

[electric ant]

I'm asking in mac forum as I want to make sure they work with my MBP(Intel SantaRosa 2.2ghz), and that it has enough power to USB /FW ports.

Ive looked at the
Freecom Mobile drives with the aluminium exterior (leaning towards this one)
Freecom Mobile Pro drives with firewire (not sure if requires external power in addition to firewire)

Anyone have any reccomendations/experiences with portable 2.5" external hard drives? Is it worth building my own ?

Thanks

Yeah I thought so, its firewire 400. But its only a 4200rpm drive whereas the USB one is 5400rpm. Hmm decisions, decisions.
