The TonidoPlug 2 is small; only an inch or so longer than a 2.5″ drive and not much wider.
At the bottom of the TonidoPlug 2 we have a RJ45 port and a USB 2.0 port allowing the connection of external storage devices.
The left-hand side of the device has a three-position switch and three indicator LED's, for power, data and wireless connection.
The top has a 2-pin power adapter socket, and this can be replaced for different countries.
Opening up the TonidoPlug 2 is just a case of sliding the top cover off. This gives access to a 2.5″ internal SATA bay. The device supports a SATA II capable interface, not SATA III.
We installed a test solid state drive; a 120 GB Kingston HyperX 3k SSD. Of course, you could fit a 1 TB 2.5″ drive for additional storage capacities.
The back of the unit is spartan. It allows for good ventilation as it is raised slightly, allowing cool air to circulate into the device.
