Using Portable storage (USB Power)

[Douggie]

Those WD Passports are 2.5" drives and from what I've understand - but correct me if I'm wrong - is that 5400rpm 2.5" drives are comparable in speed with the 3.5" 7200 rpm drives (probably because they're smaller).

But I have no idea how much SATA and IDE have impact with those external drives (the WE Passport is IDE if I recall correctly) - has anybody an answer on this?

Also, you might want to get a external HDD with Firewire if you capture a lot of video from your camera. It's more stable - or so I heard...
