Compact and robust due to its metal shell. It holds in place with its pads provided. You can also choose to attach to the wall with screws provided also. Then it is a switch, nothing to do, just to feed and connect the RJ45 cables. As for speed, I can only give a result obtained, to my own configuration: 500 Mbit / s between my PC and NAS, with cat cable. 6. As for saying this limits the flow in my config ... this proves in any case that this switch provides at least 500 mb / s :)
