not too expensive a four bay. does the job just fine for home use. Basic setting not too complicated (and very complicated if we want to set full of debts, rights, cloud, external access ....). For the investment against the NAS is not enough: I had to buy a DD in addition to those I had a Chromecast a switch, 15m ethernet cable, a pair of CPL 650 MBP and a DLNA compatible client 3D finally able to read my big 3D MKV: cost of the operation +/- 600.
