IIRC, USB2.0 sends data in bursts, Firewire/IEEE1394 keeps a constant stream. That's why you can send DV uncompressed video streams over Firewire (like from DV Camcorders), but can't do it over USB2.0.

Another factor that makes firewire quicker is the fact that you have a very small number of ports, and if I'm remembering the correct specs, each one pretty much operates independently to the others. USB ports (1.1 and 2) all operate over a single bus, so overall speeds might be fantastic, but like a network connection, it's all spread out between the stuff going on and I believe that's the reason it works in bursts.
On the other hand, I only just woke up from last night and my head still feels a teensy bit fuzzy, so I may be talking cod****. |
