The Xbox One is equipped with a 500 GB or 1 TB internal hard drive depending on what console you purchased. Most of this space is available for storing games and apps, though some is reserved for saved games, console software, and other important system functions.
A triple-A game on Xbox One can use around 20 GB and 40 GB of storage space on a drive. Installing a lot of games can quickly use up the drive space included with your Xbox One.
If you connect an external storage drive to your Xbox One for more storage space, you will be able to either use the external drive as media storage for pictures, music, and video, or set up the external drive to store games and apps on.
This tutorial will show you how to set up external storage for your Xbox One to store games and apps on.
