Transfer ultra slow !!!

On the price nothing to say about is that it's cheap, by cons have a lower transfer speed to 10MB / s on key over 8GB is just unthinkable ... Here it is difficult to arrive at 3MB / s ... I put 39min to copy file to half the size of my key (7GB of data on a key 16GB). Even the deletion takes three leaden.
(For information the same data have 1min 15s to copy onto my USB Corsair Voyager 32GB)

If you want to use that key to the stoker Word or Excel file is nickel, for cons to transfer photos or video drop (send your files by email it fast ...)
