These cables cost me very much effort and time, and I can only warn against buying. I had big problems with the transfer of large amounts of data. Have the error in the software used, etc. Finally, I came looking for times directly, without connecting this extension on the idea, the external drive with the normal USB 3.0 cable. Lo and behold, the data has been transported more than 10 times as fast. Ok, I thought, have just caught a bad cable. But I still had a copy of the original packaging 2. extension cord. And exactly the same effect! Then I informed myself in the Internet: USB 3.0 extensions must always be active and not passive cable like this one. Unfortunately, many of these non-powered USB 3.0 Extensions are offered, is without noted that max. the USB 2 speed can be achieved. With me were transferred less than 1Mb per second.
Addendum: Perhaps I should mention that my USB 3.0 cable was about 1m long. By extension, therefore, yielded 1.50 m. With USB 3.0, it is critical not later than 3 m length. For me, the 0.5m-renewals reduced in any case the rate to around one-tenth. Passive USB 3.0 extension of 5 m length are total nonsense.
