Immediately received immediately tried. On transfer of large video files (385Go) transfer rate of 30MB / s surroundings. The disc is rather quiet, I expected much more noisy, so it's a good surprise from that side. The design is simple but neat, and the different adaptable standard power system is really a plus. Travelers will appreciate, although the weight is not negligible. In short I recommend this product without any problem!
PS: Function integrated backup to disk not yet tested.
