Shorter time than advertised (received 6 days after my order) Product conforms to the description. The price is right for the capacity and performance, but beware, the actual capacity (58.5 GB formatted exFAT 128k) is less than that announced (64 GB). W7 recognized without problem. The flow rates are correct (sequential read / write 34 MB / s / 20 MB / s on USB port 2). Recognized as an external USB drive (unlike my Sandisk seen as a key disk) I used as my recorder decoder SFR and it works! So I'll buy a 2nd for my data transfers. small downside, there is no activity light.
