A box as we should do more often: 4 screws to handle, HDD to install, and hop on branch and it works. For my part, it is connected in a NAS backup. The NAS has recognized without formalities. It turns off automatically if left unattended. The transfers are very good: 110MB / s read on my gigabit network. Write: 90MB / s. SD is a Caviar Green 2to in 5400trs / minutes. I guess we can do more if you use it directly but I have not tried.
