WD Elements 4 TB USB 3.0 Desktop Drive - $107.99
If you’re willing to maximize game storage at the cost of portability, the WD Elements 4 TB USB 3.0 hard drive is for you.
Don’t load all your PS4 games on this drive. Instead, store the games that you play most often on your console’s internal storage. Move over the titles that you’d normally delete. You can play them from the WD Elements drive when you want, or move them back to your console’s internal drive for maximum performance.
The WD Elements 4 TB USB 3.0 Drive connects to your console through a single USB cable. A wall charger provides the power the massive hard drive needs. Amazon sells the PS4 accessory for $107.99.
