With games ballooning in size it's usually a good idea to have external storage options for your gaming console of choice. For those on Xbox One looking for a little extra space, the UK's Amazon Prime Day has a deal going that is worth considering. As part of its sale, the official Seagate 2 TB hard drive is available for £65, down from £88. This is pretty handy if you download a lot of games digitally or have a bunch of installs taking up precious memory.

Since it's just a standard USB input, you're not limited to using the hard drive just on Xbox devices, you can--if you so choose--plug it in to a PC or even a PS4 for a quick memory expansion. It just might just be a little strange to see the iconic Xbox green sitting next to a PlayStation device.
