    USB 2.0 is slower than FireWire for large, sustained transfers (like the kind Time Machine does) but faster for small bursts. FireWire 800 is faster than both however. Therefore, I'd say the speed limit is the interface connecting the drive to the computer.

    Thanks for the reply. So you would really only be really slow on your first backup, right? Doesn't Time Machine do incremental/differential backups so it only backs up new or changed stuff?

    Yes, Time Machine does do that - but you're still better off using FireWire 400 instead of USB, even in that case.

    For a little more that the Iomega, I'd recommend an OWC drive:

    I have the 500GB version and it's great. This one has USB FW400 and FW800.

    If you are sure you only want USB and FW400, you could save a little and get this model:

    Here's their page on all the models available:

    Great company to deal with.
