Of course, the quality and reliability of a storage solution are evaluated primarily on the long term. So from start using this record, I can not yet comment on its performance over time. However, I can give my first impressions, which are quite positive. First, the dimensions are very small, I also have a Storeva and Toshiba is even smaller. In addition, USB 3.0 offers a real performance gain in speed of data transfer compared to USB 2.0. I copy a lot of heavy photo files from my PC (Macbook, in this case) to the hard drive, and copy times are greatly reduced. The packaging and finish are very satisfactory. My only regret is the connection owner output of the disc, which is very unfortunate! In the unfortunate event that the Toshiba cable is damaged or lost, the data would be trapped in the disk without access until a new similar cable. It would have been much more sensible to use a standard USB connector. Apart from that, I bought this disc benefiting from the promotional Amazon (750 Gà the price of 500) and I am very satisfied.
