The case: The installation of the drive with 4 screws was easy. The assembly is also easy with two screws. In unscrew the housing itself but a problem had the same result. One of the two screws that hold together the housing, be could not unscrew. It has almost 10 minutes before I could open the case, because I did not want to damage. After that, everything was clear. The counter thread has come out of the plastic. And I have not tightened the screws during assembly. That would be with the filigree screwdriver that was supplied, not at all possible. The housing is held together only by two, less than a millimeter thin wafer of plastic in the mating threads as a Minimuter are embedded. It's only a matter of time when loosen this nut out of the plastic. For me, it has happened already in the first unscrew. What helps a stable aluminum housing if it is only held together fragile? In my view, this is a design flaw. The two tablets made of plastic must be replaced by two small plates. The Function: The normal functions, such as recognizing the plate by computer and data transmission works well in both USB2 and in USM3 mode. This is not self-evident. Of the three cases that I had so far, this only worked properly in USB3 mode. The other two worked well only in USB2 mode. In USB3 mode there were both grawierende problems. I had to return. Unfortunately, in this case the SMART are - data, ie the data on the health of the disk and the temperature of the plate is not passed on to PC. A deficiencies, which I can not accept. CONCLUSION: Those looking for a low-cost housing and rarely changes the plate in the housing, it can dare to buy. But who wants to monitor the board also needs access to the SMART data and on the temperature of the plate. But that can not provide the housing. Therefore, only two points.
