here are the theoretical maximum speeds for each standard: - USB 1.1 maxes out at 12 Mbps.
- USB 2.0 maxes out at 480 Mbps.
- firewire maxes out at 400 Mbps.
however, firewire should hit 800 Mbps and 1600 Mbps in future implementations of the standard. here's an actual benchmark comparing USB 2.0 and firewire. you would expect USB 2.0 to be faster, but it turns out firewire was since theoretical maximum speeds aren't always reliable. have a look. probably the more important issues are cost, chaining devices, and compatibility with older devices.

In real time test these two technologies are very close with the edge going to firewire. Firewire uses descrete channeling which will allow you to get better performance from multiple devices were as USB 2.0 will begin to bog down significantly. Also USB seems to require more overhead thus the 480Mbs is somewhat misleading. One last point. In theory, you do not need a computer to use a firewire to firewire device. But I haven't seen anybody accomplish this task as of yet.

plus you can get power out of the fire wire (6 pin plug) so you can charge the ipod and actaully use the power to drive some note book drives so its just one cable, FW is used far more, DV camera, highend Digital Cameras, HD, CDRs but costs a little more, compare the price of the CDRs USB is cheaper.
Also don't forget apple designed FW and Intel designed USB so take your pick

I've heard you can hook up a digital cam directly to a firewire HD and it will record video directly to the drive - is this true?

yes, it is technically possible, but it is still up to the camera maker to implement the feature in their hardware.

Whooosh. Did people miss the actual purpose involved in the question?
The answer is of course, it doesn't make one bit of diference speed wise for burning CDs. The speed will be determined by what the burner/software is capable of. No external optical drive comes anywhere near maxing out either a Firewire or USB 2.0 connection even at the fastest burn speeds.
The Firewire interface has its advantages (as already outlined) and USB 2.0-only enclosures and devices tend to run cheaper in price. Better yet, many newer devices have both interfaces.
