Nas server that has many options and that revolutionizes the way to manage their personal data (mainly for archiving and Backuper all my rush and montages of family movies, vhs to avchd through the hi-8). Installed with NAS Seagate 3TB disks, it remains fairly quiet (but off the night if installed in a room) and does not rise too much in temperature (to do this summer ...) Minor complaint on the rights management part of Photo Station which is not ideal, hoping that future releases will simplify things. For the rest, satisfied with my purchase!
