Ordered on 15 and 19 received in my boit'o LEtr. Fine for a product purchased from our friends "across the Channel." A first test (after formatting NTFS) allowed me to see a copy of a "avi" file of 701 MB in 19 seconds via usb3. The en.lecture access to the key (via usb3 always) is as fast as reading on the hard disk ....... Beh, there must be a difference, but not visible without chrono .Some critics say the shell is plastic and that this must be fragile, but I think as long as I do not use me as chisel or screwdriver that should do it! IN BRIEF: quickly arrived home, execution time more than respectable transfers, plus a nice design.
