Hi folks, I'm about to buy an external hard drive for my MacBook Pro to use for backups and storage. What are the advantages/disadvantages of USB 2 and Firewire. My early MBP only has Firewire 400, not 800, so would I see any benefits in backup speed or reliability with a Firewire drive? Or save some cash and just go with the USB 2 drive? Thanks for your input, Effortless.
