Once I had to send back a 2TB hard drive from a different manufacturer as useless a week before (see other review), I ordered this Samsung 1TB drive. Unwrapped, connected works. Up to 120 MB / sec I was able to test over USB 3.0. Besides an attractive appearance, soft sound. The USB cable has to be connected to the hard disk its own plug, no standard connector. But that's really a minor matter. I chose the Samsung because it does not "fully negative" review showed. In most other disks there were always a few "total failure", unfortunately.
