I am absolutely satisfied with the price you can not go wrong anyway and the manufacturer Sandisk either. Just when you really need to bring fast times a file from A to B and no VDSL line is nearby, the drive is well suited for transfer rates measured as follows:
Block Size 1M average 91.6 MB / sec min 45.9 MB / sec max 134.8 MB / sec Access Time: 0.9ms
