So far, I was not Synology term, have a few years a Buffalo NAS. Was ok, but just older. Then I came across Synology. Have the station equipped with 2 x 3TB without file protection, because I'm going to parallel multiple backups, using the backup function of the station. After initial problems with USB3 disks, the hotline had no solution, the station now runs absolutely reliably even with USB3 disks. I do not know what was going on. This station met my expectations fully. On the one hand by the functions of the station itself. On the other hand by the many great apps that experience also a regular update. Class is also the Survillance function, unfortunately, is another camera license with about 50 very expensive, a D-Link camera costs just 80th Still 5 points.
