Very good portable hard drive. Good build quality, it looks pretty solid. As it is a 2TB, it is a little thicker than other portable hard drives (maybe 2 mm), but it does not bother so much. The transfer speed USB3 is very good for this type of product. Tested USB1, USB2 and USB3, it works every time. Provided with a small pouch, which protects nothing at all, but at least has the merit of being there. It can store the hard drive with its cable without the need to buy. If you look real hard disk cover, I recommend the beez covers that are very protective. I can give my opinion on the software suite supplied with the hard drive has been reformatted right out of box in exFAT to allow compatibility between Windows, Mac OS, and Linux. Purchased 3 copies, one red, one black, one blue, which are 100% identical except for their color. I have a slight preference for blue, but it's a matter of taste. I can give my opinion on the reliability of the product, but Western Digital is one of the most reputable brands reliability level.
