worked for about 5 minutes (the time to format and test the transfer rate) and more recognized even if the power was turned on but can not transfer files. The recorded transfer rate was only 33 mb / s which corresponds to USB 2 but not 3, when it should be close to 100 mb / s usual rate for HDD, SSD (external boxes) and USB KEY 3 fast. If the case was not, there is no point in reverse and fast SSD HDD Of course it is cheap ?? The seller is located in China, but the contact was rapid and serious, because the price of 27 euros return for China, the seller has not demanded the return and paid the refund. So good positive point at least on this point.
This kind of product should show the transfer rate, the new well-ordered these rates specified ensuring value for SSDs in particular, since this case was to receive that kind of drive.
