The positive reviews I can associate myself with a clear conscience. The anchor USB 3.0 SD card reader was automatically recognized by Windows 7 and works reliably and fix. The Transferate is approximately three times faster than with my USB 2.0 Card Reader. Actual transfer speed depends on the file size and file type. Small files are transferred more slowly, more quickly. However, this applies equally to SSD's and HDD's and is not a fault of the device, but technically unavoidable, ie not attributable to the device. Furthermore, one should remember that the speed of data transfer is determined not only by the card reader, but also on the used memory card, the Main board and the utilization of the computer, the hard drive speed, etc. Therefore, as end-users, we measure the speed of the overall system. On my elderly 32-bit system, the read performance is between 40 and 90 Mbit / sec and write rate between 15 and 25 Mbit / sec via the USB 3.0 input newly installed. That's very neat and much faster than the transmission to the cable directly from the camera while transferring the RAW files from the camera. Processing Ankergräts is solid, easy handling. Only the width is unfortunate, because the use of directly lying next to the second USB port on the computer is fiddly by a stick. Slightly slimmer would better design. That would be my suggestion to Anker.Die 'missing' covers were previously known to me and I think it is an advantage because I can not lose. Who they are important, other models can buy. Overall, a good product, that full credit is justified.
