My overall impression after a few days of use:
The NAS works as it should, is in operation quite quietly and also to look chic. The latter point is rather irrelevant to me, as the appliance is in the living room closet with me. On the tablet and smartphone app can not be faulted: normal access to the data via folder structures, as one is generally accustomed.
Facility operation and Integration in the network:
Basically, the process is not difficult to accomplish and I think also for the normal average user; despite the rather short held quickstart. About a couple of things I am but stumbled at the start. Maybe help the following description also other purchasers of WD MyCloud EX2
1) Access to the data on the Windows Explorer was first not possible:
Whenever I wanted to integrate the NAS as a network drive on my Windows laptop to access the data on the Windows Explorer, which does not work (Error message: Network path was not found). Access to the Dashboard on the web browser and access to the data on the WD My Cloud program worked properly, however. What was the problem? OK, harsh words ;-) The firewall on my laptop prevented access.
2) Initially very slow copy operations on the WD My Cloud program:
First, were all tasks that I performed on the WD My Cloud program, infinitely slowly (problem is also described by other users). For me the performance is now good, since I have solved the problem described in item 3. Therefore, I suspect that this is a causal relationship could exist.
3) Produced Ralaisverbindung for cloud access:
Whether a relay connection is established, you see the Dashboard, under cloud access, connection status (either relay connection or port forwarding connection). What does this Relaisverbingung (information I have from other reviews / forums)? If the WD MyCloud can not connect from the Internet via open ports on the router (or these can not open itself because UPNP is disabled), a connection is established via a WD server obviously to still access the data from to allow the Internet. But on the one hand I do not want that my data on a WD server running on the other hand that might be in my opinion the reason for the original performance issues. What to do? Alternative 1) The ports 80 and 443 on the router manually unlock the WD MyCloud EX2. Here one would have even further in the Dashboard WD MyCloud EX2 under Settings / General / cloud access to manual configuration switch. I did that. Alternative 2) Enable UPnP on the router; The NAS needed ports can then open themselves. Of this I have refrained, as this gem. Internet research could be a security risk well.
CONCLUSION: After minor, initial problems with the facility now everything works as desired.
