    I have the base Retina MBP model, 2.3/8/256. I made a clone of my hard drive using a Seagate GoFlex Thunderbolt Adapter and a Seagate 500GB, 7200rpm drive. I had to purchase the Apple Thunderbolt cable.

    It took 20 minutes to move the 80GB and make the clone, using Super Duper.

    The Thunderbolt Adapter does get warm.

    It is because it is an active cable.

    Wow, 80gig in 20 mins, sounds awesome.

    Do we know how long it would have taken with USB2.0 and a 7200rpm external 2.5" HD just for comparison?

    USB 2.0 is the limiting factor, as it offers only up to 37 MB/s, even a 5,400 RPM HDD would be faster than that (75 MB/S).
    With USB 2.0 at roughly 35 MB/s, 80 GB would take 39 minutes, theoretically, if the transfer speed would be constant, but USB 2.0 is not that constant.

    80 GB with 2.0

    As I recall, it would take about 45-60 minutes for a transfer, using 2.0
