If you have a broadband box and a PC is connected, and that you plan to use the router box, careful to verify that the box of your router is 1 Gb / s! this is not the case with freebox crystal for example, only with the revolutions. Having a freebox 100 Mb / s, I found myself with transfers from PC to NAS 8MB / s ... I had to buy a switch 1Gb / s on amazon (13) to connect the box, the PC, the nas to switch and since I am 1000 Mb / s or about 80MB / s PC => Nas. In short, a small detail auxquel we do not necessarily think. Otherwise the whole very good NAS, setup is easy. Delivery amazon on time delivery except idiot tnt I lost 3 days, amazon refunded me without question the harbor premium .. nobody does that =)
