    Bit of a random (or not) question, but it's been bugging (not too much though) me lately.
    I have a couple of USB hard drives hooked up to a hub, which is then connected to my MBP. If I grab a folder from Drive A and copy it onto Drive B, does the data come all the way down to the MBP through that single USB cable, and then all the way back up again, or does it magically shuffle it's way directly from one drive to the other?

    I'm thinking it probably takes the scenic route, wasn't one of the advantages of firewire that it could be a bit smarter about that sort of thing?

    Cheers guys!
