I replaced a D-Link this product and I'm very happy. Very quiet, it is installed in the lounge connected to Neufbox and virtually inaudible even at full load. Enough reagent copies of all file types, even wifi. The PS3 plays video files without freeze. I installed two Western Digital 1TB drive, Red model, raid 1. Browser interface, clear, in French, but lacks a little aid for all functions installed in the system. I recommend occurs.
