I was looking for a hard drive 1 TB self-powered and attractive price of it made me spend a few dollars more for an enlarged capacity in a small volume (11 x 8 x 1.5 cm, the size of a smartphone) that easily fits in a pocket. The seriousness of the brand has finally convinced me, and I am quite satisfied with my purchase, both in terms of speed than the muffler of the disk (it does not hear !!) and his strength: he decided dive from the top of a table on a tiled and has no sequel that dive at high risk. In short, a hard disk to recommend without hesitation as its vendor (Schwanthaler Computer GmbH), serious and responsive due to a problem on the hard drive cable, which was sent back immediately.
