Listed on an EA FAQ page for Battlefield 4. It is recommended that gamers install both discs onto the Xbox 360 hard drive for the best experience of the game.
The first time you start your game, regardless of which disc you use, you will be asked to perform a required installation of 2 GB worth of game content to your hard drive.
In addition to the required installation, each disc has additional content you can install to your hard drive for better performance.
- The Multiplayer Disc, or Disc 1, has an additional 6.6 GB of content
- The Single Player Disc, or Disc 2, has 5.8 GB of installation content.
We highly recommend performing these additional installations to make sure you have the best experience possible in Battlefield 4.
So make sure you have at least 14GB of space spare on your Xbox 360 hard drive if you want to go with the recommended route.
