Ease-of-use: The plug-and-play functionality of the 3S allows you to start backing up your equipment the moment you take the unit out of the box (3S550 & 750 only). Gain automatic integration with Windows, Mac and Linux with a simple connection to a USB port.

EcoControl: The 3S manages your energy efficiency for you with EcoControl Master/Control outlets (model 3S750 only).
