The PlayStation 4 - like the Xbox One - includes a 500GB internal hard-drive, which for many is filling up fast.
You can already expand the PS4's storage, but in a limited fashion. Internal storage is restricted to 2.5" hard-drives, and you can't easily use external storage for game saves and installation. This is a problem. What to do?
Video game peripheral maker Nyko's answer is the Data Bank, a dock that attaches to your PS4 and lets you expand the console's storage in an easy and clever way.
The Data Bank replaces the top of the PS4 as well as its 2.5" hard-drive, letting you use larger and often cheaper 3.5" hard-drives the console considers to be internal storage.
"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.
"The design of the replacement dock lid seamlessly matches the minimalist design of the PS4. Once a 3.5" drive is slid into the Data Bank, a built-in LED strip illuminates while the console is accessing its memory."
PS4 owners have already worked out how to get huge hard-drives working with the console. The video, below, explains how to set-up a PS4 to work with up to 6TB hard-drives. The Nyko Data Bank should make the process simple.
There's no price or release date yet, but we expect the Data Bank to launch during the first half of 2015.
Meanwhile, Nyko also announced the Type Pad, due out during the first half of 2015. This Bluetooth device attaches to the bottom of a DualShock 4 controller. There's even a mini-analog nub.
