    instead of an SSD, the Surface 2 uses a eMMC Flash module as a hard drive. First I thought my USB 3.0 Hard drive was broken, because it copied movies very slowly to my Surface's hard drive.
    But then I checked for the writing speed of the Flash module, and I find it a bit disappointing, only 31 MB/s. USB 3.0 does only make sense, when you copy something from your Surface.
    Do you have the same speed? You have to write the following command in your console:

    winsat disk -seq -write -drive c

    the results are random, sometimes the unit seems very slow and in some test is 2x faster..

    You might be having an update running in the background.
    Or some other background task maybe
    The disk shows up as samsung mbg4gc. I wonder what that is. Even google doesn't get results.
