Have the MyCloud 4TB now since November 2014 in use and so slowly adjusts the disillusionment. In principle, it's a great part, if everything would work as it should. By MyCloud I total of 5 different plates (external, internal, network) can resolve what bring a lot of space and creates order. Installing and setting very well and just worked without many problems. What then has yet taken some time was, move the files. (1.5 TB). OK such amounts of data can not move so well all day so I would not see that as negative point. As for the performance, it is possible without problems of 2 computers from videos stored on the disk to see. But now come the disadvantages which unfortunately continue to rise. What is not possible, unfortunately, to access to a share without public access to 2 different users at the same time plan. You have to turn denöffentliche Access To make this possible. For me, the biggest drawback is that you can access without any problems nich with the apps on the MyCloud. At first I had only the Android App WD MyCloud installed on my mobile devices and was able to access all the files. However, with photos then problems began, which showed up as follows: First, no thumbnails of the images were available. After the MyCloud had finished content creation then I could see all the pictures in thumbnail mode. Then click on it and view image not possible. The picture you have to first load down to it then to be seen. So tested the app WD Photo and then I could about half the photos the others were not possible. After far inconclusive lengthy contact with Western Digital is now ready indicating the WD Photo app no longer on the screen and MyCloud app thumbnails missing without changing anything. Get the MyCloud retain Although they halt replaces several individual plates with me, however, an additional profit through the mobile access I do not see.
