Western Digital's reputation is more to do, and that is not what NAS box will be an exception. Design sober, it is important even if this type of disc does not necessarily throne on a desk. Very easy installation, a software to download on the WD website, you run, you follow the steps and you're connected. access is on the local network (easily) or via the Internet through smartphones programs or applications (Android or iOS). I met some connection problems, but I am a novice in terms of REAL SIN, the problem may come from me. The configuration of the box and different accounts is done through a clear interface. Operation is intuitive and discs are more than respectable size (4TB for my version, configured with 2TB backup) Great product, but works much better at home in local access in the cloud.
