It doesn't require an additional power source and simply plugs into the USB port on your Xbox One console. We try not to lean into this hardware-reviewing trope too much, but this is a product that "just works". It has read and write speeds that are standard for any HDD device and comes with a two-year warranty as standard. If you want to use it for a PC too, it has password protection and automatic file back-up, which are both useful features that elevate this model above our previous budget pick, the Canvio Basics.
