Massive storage in one tidy box. The improved visual fidelity of modern computer games has come at the inevitable cost of storage space. Want to install the likes of Gears of War 4 or Forza Motorsport 7? Reports suggest you'll need roughly 55GB and 70GB, respectively, and those estimates are only likely to increase as games begin to adopt substantial 4K assets.

Given the weight of these games, it's a surprise that consoles continue to ship with limited internal capacity. A standard Xbox One S or PlayStation 4 offers just 500GB to play with, while the Nintendo Switch ships with a paltry 32GB, and though the Xbox One X and PlayStation 4 Pro come equipped with 1TB, that's still a limited amount for a growing game library.
