TrekStor DataStation maxi light 2TB external hard drive (8.9 cm (3.5 inch), 5400 rpm, 15 ms, 32 MB cache, USB 2.0) Black (Personal Computers)
The external hard drive from Trek goals is highly recommended. The running noise is barely audible; the transmission speed is more than sufficient. In addition, the hard drive nor a separate on / off switch, which I think is very useful.
