External HardDrives, which one is best?
I've been looking at the MyBook and MyBook Premium but they're quite expensive any other options?
Will USB 2.0 be fast enough for file transfer or will I definately need firewire?
How much of a difference in speed will I notice between external and internal harddisks? I.e. how long does it take to open a 50Mb file (photograph, movie etc) on internal disk, USB 2.0 connected external HD and Firewire connected external HD?
