A round product

I take this disk as a backup unit and am very satisfied so far. It is extremely compact, portable, well made, cheap and compared to my other hard drives for USB 2 remarkably fast. The supplied software I do not use other than the disk drive and can not therefore judge.
The only slight downside for me is the "volume": The disc rushes - although only extremely quiet, but for the delicate ears hear (my computer is standing next to me under the table). So I let them not permanently on the computer, but close them only when I need them.
Nonetheless, I would recommend them without reservation.
