You will be able to use the larger, and cheaper, 3.5" hard drives for your Sony console.
The Data Bank is a device that connects to your PS4 and allows the use of 3.5" hard drives, over the normal use of the system's 2.5" one. Sitting on top of the console, the Data Bank blends in with its sleek design.
The device has been created by Nyko, a manufacturer of accessories for consoles.
"The solution eliminates the need for an external hard drive, which currently cannot support game installs or save data," Nyko said at CES this week.
"This also allows for larger storage, faster running speeds and less expensive prices found with 3.5″ hard drives."
No price or release date has been revealed for the device yet, but the Data Bank is planned for a "first half" 2015 release.
