The original PlayStation 4 included 500 GB of storage.
Sony launched the PS4 in November 2013 with a built-in 500 GB hard disk drive. That space held the operating system, installed games, downloadable titles, patches, saved data, screenshots, and video clips. The advertised capacity was not entirely available to users because the system reserved part of the drive for system software and other functions.
The PS4’s storage was user-replaceable, allowing owners to install a larger internal drive. Sony later expanded the family with the smaller PS4 Slim and the more powerful PS4 Pro. The Pro commonly appeared with a 1 TB drive, which is one reason the original model is sometimes confused with later versions.
Another common mix-up is memory: every PS4 model included 8 GB of GDDR5 system memory, but that is RAM, not long-term storage. Sony also added support for external USB hard drives in 2017, making it easier to manage the increasingly large downloads associated with the console’s digital game library.
