The original PS5 Digital Edition has 825 GB of internal storage with about 667 GB available to the user, which was Sony's launch figure, and it is the PS5 that needs extra storage most. A later system update unlocked the M.2 expansion slot, so you can fit a compatible SSD with a heat sink under the side cover; Sony's list of requirements covers size and speed. USB extended storage can hold PS4 games and store PS5 games. To free space on the console, open Settings, Storage, Console Storage, sort by size and delete finished games, since saves stay.
Large games, DLC and update files take the most. Captures and videos can be moved to a USB drive or the cloud. The original consoles also keep PS4 games that run through backward compatibility, and each takes space too.
The checks in more detail
Compare the real usable figure with what you expect before assuming the drive is faulty. On a 2020 console the internal drive has also seen years of installs and deletions, so fragments of old updates and cached data can occupy space that Console Storage does not show clearly. A rebuild of the database in Safe Mode tidies those and can return a few gigabytes. If you plan to add an M.2 SSD, check that your console has the latest system software first, because the slot was enabled by an update, and that the drive's heat sink fits under the cover.
Check Settings, Storage, Console Storage, Games and Apps for any games you installed twice, such as a PS4 and a PS5 version of the same title, since both can be installed and each takes space.
