The PlayStation 5’s internal storage disappears fast once you install a few modern blockbusters, and in 2026 a quality M.2 expansion drive is close to essential. Sony’s requirements are specific, though: you need a PCIe Gen4 NVMe drive that sustains high read speeds and, critically, one that stays cool with a proper heatsink so it does not throttle mid-game. Not every fast SSD qualifies, which is where careful selection pays off.
We focused on drives that meet Sony’s performance bar, install cleanly in the console’s expansion bay, and hold their speeds under sustained load. From officially licensed heavyweights to value-packed high-capacity options, these are the best M.2 SSDs to expand your PS5 without compromise.

Watch: Best M.2 SSD For PS5 2026 — Video Review
How to Choose an M.2 SSD for PS5
- PCIe Gen4 requirement: The PS5 needs a Gen4 NVMe drive rated for at least 5,500MB/s, so Gen3 drives will not work properly.
- Heatsink is mandatory: Choose a drive with a low-profile heatsink, or one designed to fit the bay, to prevent thermal throttling during long sessions.
- Capacity planning: A 2TB drive stores dozens of large games, while 1TB is a budget-friendly starting point if you rotate titles often.
- Physical fit: The heatsink must clear the expansion slot cover, so avoid oversized aftermarket coolers that will not close.
- Endurance rating: Higher TBW figures signal a drive built to withstand years of installs and deletions without wearing out.
The Best PS5 M.2 SSDs Reviewed
WD_BLACK SN850P 2TB
Officially licensed by Sony, the SN850P is purpose-built for the PS5 with speeds up to 7,300MB/s and a heatsink shaped to fit the bay perfectly. It is the safest, most hassle-free choice for anyone who wants guaranteed compatibility and top-tier performance.
Samsung 990 PRO with Heatsink 2TB
The 990 PRO remains a benchmark drive, hitting 7,450MB/s reads with its integrated heatsink keeping temperatures firmly in check. Its excellent endurance and efficiency make it a superb long-term pick for gamers who also use the drive on PC.
Lexar NM790 2TB
Offering 7,400MB/s reads at a noticeably friendlier price, the NM790 is the value enthusiast’s favorite. Its single-sided design and included heatsink make PS5 installation simple, delivering flagship-class speed without the flagship price tag.
Corsair MP600 PRO LPX 2TB
Explicitly optimized for the PS5, the MP600 PRO LPX pairs up to 7,100MB/s reads with a slim heatsink engineered to fit the console. It is a proven, reliable choice that has been a community favorite since expansion support launched.
Fanxiang S660 1TB
For gamers on a tighter budget, the S660 delivers PS5-ready Gen4 speeds and a pre-installed heatsink at a very approachable price. At 1TB it is an ideal entry point for expanding storage without a large upfront outlay.
Frequently Asked Questions
Do I really need a heatsink on my PS5 SSD?
Yes. Sony requires effective cooling, and without a heatsink the drive can overheat and throttle during long sessions. Every drive here either includes one or is designed to fit the bay safely.
What speed does the PS5 require?
Sony recommends a PCIe Gen4 NVMe drive with sequential reads of at least 5,500MB/s. All of the drives above comfortably exceed that, with several pushing past 7,000MB/s.
How do I install an M.2 SSD in the PS5?
Power down, remove the console’s side plate, unscrew the expansion slot cover, seat the drive, and secure it. The system prompts you to format it on the next boot. The whole process takes only a few minutes.
Is 1TB enough or should I buy 2TB?
It depends on your library. 1TB adds meaningful room for a budget price, but modern games can exceed 100GB each, so 2TB is the sweet spot for players who keep many titles installed at once.
Final Thoughts
Expanding your PS5 is one of the best upgrades you can make, and the drive you choose comes down to budget and peace of mind. The officially licensed WD_BLACK SN850P is the fuss-free premium pick, the Samsung 990 PRO doubles as a stellar PC drive, and the Lexar NM790 and Fanxiang S660 deliver excellent value at 2TB and 1TB respectively. Confirm Gen4 speed and heatsink fit, and you will never see that low-storage warning again.
