The PlayStation 5 was the first PlayStation console to use a solid-state drive for built-in storage.
Sony designed the PS5 around a custom NVMe solid-state drive, replacing the mechanical hard disk drives used in the PlayStation 3 and PlayStation 4. Its high bandwidth and custom input-output system were intended to reduce loading times and allow developers to stream game data more quickly.
The standard PS5 model was marketed with an 825 GB internal SSD, although usable capacity is lower because system software occupies part of the drive. The Digital Edition uses the same basic storage architecture but omits the physical disc drive.
The PlayStation Vita used flash-based removable storage cards and internal flash memory in some models, but it was a handheld rather than a home console and did not establish the PS5’s custom high-speed internal SSD design.
