I have a USB 3.0 flash drive.  When I copy a large test file to the drive from my desktop system, I get a 45mbs throughput.  When I insert the drive into the B115-MP and copy the same file. it never gets above 1mbs.  What am I missing?  I don't a driver is missing, but I am open to advice.

    OK, I have found out something interesting.  The USB drive I have been using is a USB 3.0 drive.  When connecting it to the USB 2.0 port on the side of the laptop, the throughput is very slow (< 1mbs).  However, when I connect it to the USB 3.0 port on the back of the laptop, the throughput is OK (>45mbs). 

     

    When I connect a USB 2.0 drive to the USB 2.0 port, the throughput is faster than when connecting the USB 3.0 drive.  Not sure why, but as long as I understand how things are working, I can live with it.
