    Just bought an external hard drive and it came with a USB 3 cable. I can exchange it and get the same hard drive without the cable for $20 less. Does USB 3 work on the MBP or would it be better to exchange my external for one without the cable?

    No Mac model has a USB 3.0 port and it's very likely that they never will. It won't work at USB 3.0 speed.

    It will work as they are backwards compatible but it won't transfer at USB 3.0 speeds obviously.

    It will work on your Mac. USB 3 is backwards compatible with USB 2 (which is the one on your MacBook Pro). It just won't be as fast as USB 3.

    EDIT: aeboi beat me to it.

    I didn't mean it won't work at all. I meant it won't work at USB 3.0 speeds. USB has always been backward compatible, running at the lower speed.
