Key takeaways
- PCIe Gen4 requirement: The PS5 needs a PCIe 4.0 x4 NVMe M.2 drive; Gen3 drives will not meet Sony’s minimum speed, so confirm the generation before buying.
- Read speed target: Sony recommends at least 5,500MB/s sequential read, and drives like the Samsung 990 PRO comfortably exceed it for headroom on the largest games.
- Heatsink fit: A low-profile heatsink is essential; officially licensed drives like the WD_BLACK SN850P are pre-fitted to slot in without clearance worries.
- Capacity for your library: 1TB suits casual players, but 2TB is the sweet spot in 2026 for storing multiple large AAA installs without constant deleting.
- Form factor: Stick to the M.2 2280 length, which is the size the PS5 slot is designed around for a secure, flush fit.

Frequently Asked Questions
Does any M.2 SSD work in the PS5?
No. The PS5 requires a PCIe Gen4 x4 NVMe M.2 2280 drive that meets Sony’s speed minimum. Gen3 drives, SATA M.2 drives, and oversized form factors will not work, so always verify the specifications before purchasing.
Do I really need a heatsink?
Yes. Sony requires effective cooling for the expansion slot, and drives can throttle or fail without one. Choose a drive with a pre-installed low-profile heatsink, or add a compatible one that fits under the PS5’s cover.
What speed does the PS5 SSD need?
Sony recommends a sequential read speed of at least 5,500MB/s. Most quality Gen4 drives in 2026 exceed this easily, and higher-rated drives like the 990 PRO provide extra headroom for the largest, most demanding game installs.
Can I move installed games to the new SSD?
Yes. Once the drive is installed and formatted by the console, you can move existing PS5 and PS4 games to it from the storage menu, freeing up internal space without redownloading everything.
Final Thoughts
Expanding your PS5 storage in 2026 is one of the easiest and most rewarding upgrades you can make.
