Key takeaways
- PCIe 4.0 requirement: The PS5 requires a PCIe 4.0 NVMe drive; a Gen 3 drive will not meet the speed floor, and a Gen 5 drive works but runs at Gen 4 speeds inside the console.
- Read speed floor: Sony mandates at least 5,500MB/s sequential reads, so verify the rated speed; most quality Gen 4 drives clear this comfortably.
- Built-in heatsink: A heatsink is required, and drives that include one rated for the PS5 slot save you the hassle and risk of fitting your own.
- Capacity: Given how large PS5 games are, 1TB is the sensible minimum and 2TB is the comfortable choice; 4TB exists if you never want to manage storage again.
- Officially licensed vs standard: Officially licensed drives are validated for the PS5, but many standard Gen 4 drives with the correct specs and a compatible heatsink work perfectly and cost less.
What's inside
Your PS5’s internal storage disappears faster than you expect, and expanding it with an M.2 SSD is the single best upgrade you can make to the console. The good news is that compatible drives are faster and cheaper than ever in 2026, and installation takes only a few minutes with a single screwdriver.
Sony sets firm requirements for PS5 expansion drives: a PCIe 4.0 M.2 NVMe SSD with sequential reads of at least 5,500MB/s and, critically, effective cooling. This roundup focuses on drives that meet or beat those specs, with special attention to which ones ship with a heatsink so you can install and forget.

Frequently Asked Questions
What M.2 SSD is compatible with the PS5?
You need a PCIe 4.0 M.2 NVMe drive with sequential reads of at least 5,500MB/s and a heatsink that fits the expansion bay. Officially licensed drives guarantee compatibility, but many standard Gen 4 drives qualify.
Do I need a heatsink for a PS5 SSD?
Yes. The PS5 requires effective cooling for expansion drives, so either buy a drive with an included heatsink or add a low-profile heatsink that fits within the bay’s height limit.
How much SSD storage should I add to my PS5?
1TB is the practical minimum given modern game sizes, while 2TB offers comfortable headroom for a large library. Go 4TB only if you refuse to ever uninstall games.
Is installing a PS5 SSD difficult?
Not at all. It takes a few minutes with a single Phillips screwdriver: remove the console’s side plate, unscrew the expansion cover, seat the drive, and the PS5 formats it automatically on the next boot.
Final Thoughts
For a guaranteed, no-thought upgrade, the officially licensed WD_BLACK SN850P is the safest pick, while the Samsung 990 PRO with heatsink matches it on speed. Budget-minded gamers should grab the fanxiang S660 or MOVE SPEED HB7450 for excellent value with the heatsink already included. Any of these drives meets Sony’s requirements and will end your storage headaches for the rest of the console’s life.
