Work on USB 2 computers

I submit: If the cable fits, it must transmit.

(Yes.)

It depends on the computer and OS. USB 2.0 can be up to 95% of the speed of FW400.

My experience has been that FW 400 is at least 50% faster than USB 2.

Depends on what you are doing with it.

Your experience is biased. Apple always treated USB 2.0 as a ginger step-child in both hardware and software. USB 2.0 under Windows can have faster continuous throughput than FW400 on any Mac.

USB2 on the 2010 macbook was much faster than anything that preceded it. I've seen transfers up to 40mb/s - right up there with the fastest FW400.

FW400 and USB 2.0 from 2004, FW400 read speed: 38 MBps


USB 2.0 on a Mac compatible USB 3.0 card with Mac drivers (2010), USB 2.0 read speed: 38 MBps


After 6 years USB 2.0 reached about 90% of the best results for FW400 on a Mac. It will be lots slower than USB 3.0, but new hardware running over USB 2.0 with a recent version of OS X can be surprisingly fast.
