A:Answer Hi Zopie,
The answer is a resounding yes to your question. By plugging this device into the usb port located in front of your PS4 and leaving it attached, you are able to store more games onto this external hard drive and play them, too. When plugging this device into the ps4, it will prompt you to format the hard drive to be compatible in downloading ps4 games as well as running the ps4 operating system. Don't worry about this process as it'll only take a couple of minutes at the most if not seconds.
