Search results show two main options for PS5 storage expansion: solid‑state drives (NVMe SSDs) and traditional hard disk drives (HDDs).
Some NVMe SSD options in the results are described as officially licensed, certified, or tested for PlayStation 5 compatibility.
Many portable drives advertise rugged features such as water/dust resistance (examples include IP65 or IP66 ratings) and drop protection; some listings specify drop resistance up to about 3 meters (9.8 ft).
Warranty coverage in the results generally ranges from a 3‑year limited warranty up to a 5‑year limited warranty.
Results indicate external HDDs are presented mainly for storing and archiving (for example: play/store PS4 games and archive PS5 games). PS5‑rated NVMe SSDs with heatsinks or official certification are described as allowing games to be played directly from the drive.
