Yes, the only thing about firewire is that it's a little bit faster but not by much. Each has its own advantages. But as far as Firewire 400 VS USB 2.0 you will not notice much of a difference. But comparing Firewire 800 to 400 and USB 2.0, the transfer speed on Firewire 800 is 320Mbps faster than USB 2.0. But regardless of that, both Firewire 400 and USB 2.0 need external power to burn anyways unless you are using a DVDRW Laptop slim drive as an external burner as this is where USB might have an advantage.
