My G4 Digital Audio doesn't have Firewire 800 - and since I'm about to buy a new external drive is there a big difference with drives that offer FW800? The OWC one I'm looking at can be had either just FW400 or FW400/FW800 and USB 2.0
Thanks for your advice.

FW400 has a trasfer rate of up to 400 Mbit/second, FW800 is up to 786.432 (800) Mbit/second.
So, you could buy a PCI FW800 card if you wanted, and get faster speeds.

He won't get any more performance out of FW800 than FW400 with a single external drive.

Why do you say that?
I have an external drive that has FW800 and FW400 connections. Connecting via the FW800 is markedly faster then the FW400.

Actually, scratch that. Sequential transfer rates of a modern 7200 RPM SATA drive are about 60 MB/s, so yeah ... Firewire 800 would give you about 25% more performance than Firewire 400, but only with a really fast drive.

The 750G Seagates are closing in on 80MBps (StorageReview got 78.5), which is about the practical limit of FW800.

That's funny, because it took me twice as long to backup my 100GB music library to an external drive using FW400 than it did FW800.

Yeah, that's bound to happen with track density skyrocketing upwards. Perpendicular FTW.
