Works so far wonderful, in itself is also fairly quiet. However after a while goes into sleep mode, so that access takes a few seconds. As a rule, however, without problems. The only drawback in my opinion, that the unit does not start automatically when the computer starts. Have the IcyBox to a USB 3.0 hub that is connected directly to the computer. Must therefore the PC and the IcyBox start separately. In addition I have not found a solution.
