On paper, this NAS is extremely correct. However, since I have the WD Photos app has worked at the beginning when I had some photos on my NAS. Since I use the NAS so "normal" WD Photos longer works. I applied for help to the support end of June, and despite trade with the carrier, despite the time spent debug logs and provide them, I still have not fix or even promise or patch a possible correction date (we 12 August, two months later). Another example: the "Dropbox" application, which is listed on their website, however, does not exist in the list of installable applications on the NAS. As for the possibilities of configuration, they are limited. I wonder, for example it is not possible to index a portion of photo folders (random, those containing photos) ... So, I find myself with pictures of all my disk including the covers of my albums of music. My impression is that the NAS fulfills 90% of what it promises, it starts from a good intention, but is not fully developed (not fully tested), which is unfortunately not enough for j 'in am satisfied, as a developer myself. That said, its basic functions, it works quite well, is very quiet, actually goes into sleep when I do not use it ... It all depends on what you want, but a basic NAS, there are surely cheaper; about a complete NAS Cloud Storage that also, there are better finished ...
