Your PlayStation 5’s internal storage fills up fast, and in 2026 a growing library of hundred-gigabyte blockbusters makes an M.2 expansion drive practically mandatory rather than optional. The good news is that PCIe Gen4 NVMe SSDs have never been more affordable, so adding a terabyte or two of blazing-fast storage no longer means paying a painful premium.
Not every fast drive is a good fit for Sony’s console, though: the PS5 demands sustained read speeds of at least 5,500MB/s and, crucially, proper heat dissipation to avoid throttling during long sessions. We compared the standouts below for compatibility, real-world load times, and thermal behavior so you can slot one in with confidence and get back to playing.

Watch: Best M.2 SSD For PS5 2026 — Video Review
How to Choose a PS5 M.2 SSD
- Speed rating: Sony requires a minimum of 5,500MB/s sequential read, but aiming for 7,000MB/s or higher gives you headroom and future-proofs the drive for later firmware updates.
- Heatsink is essential: The PS5 slot runs hot, so pick a drive with a low-profile heatsink built in, or plan to add one, otherwise the SSD will throttle and stutter.
- Capacity vs. cost: A 1TB drive is the budget sweet spot, but 2TB has become far more affordable and is worth it if you keep many large games installed at once.
- Form factor fit: Confirm the drive is single-sided M.2 2280 with a heatsink that clears the PS5’s cover; oversized coolers will not fit under the expansion bay lid.
- DRAM vs. DRAM-less: DRAM-less drives with a large SLC cache handle gaming fine, but a drive with dedicated cache holds performance steadier during sustained large file transfers.
The Best PS5 M.2 SSDs Reviewed
WD_BLACK SN850P 2TB
Officially licensed by Sony, the WD_BLACK SN850P is the plug-and-play safe choice, arriving with a perfectly sized heatsink and read speeds up to 7,300MB/s. There is genuine peace of mind in a drive validated for the console, and in testing it delivered near-instant loads and rock-steady temperatures, justifying its premium for players who want zero guesswork.
Samsung 990 PRO with Heatsink 2TB
The Samsung 990 PRO pairs class-leading 7,450MB/s reads with Samsung’s proven controller and NAND, all under an integrated heatsink that keeps the drive cool inside the PS5. It is equally at home in a high-end PC, so if you value versatility and top-tier endurance alongside console duty, this is the drive to beat.
Acer Predator GM7 1TB
For value hunters, the Acer Predator GM7 hits up to 7,400MB/s at a price that undercuts the big names, making it a smart single-terabyte pick. You will need to add a thin heatsink since it ships bare, but once cooled it performs indistinguishably from pricier drives in day-to-day gaming.
Lexar NM790 2TB with Heatsink
The Lexar NM790 delivers 7,400MB/s reads and a generous two terabytes with a low-profile heatsink, striking an excellent balance of capacity, speed, and cost. Its single-sided design fits the PS5 cleanly, and the SLC cache keeps game installs and loads snappy, making it our favorite high-capacity value option.
fanxiang S660 1TB with Heatsink
If you want to expand storage on a tight budget, the fanxiang S660 includes a heatsink and hits up to 5,000MB/s, comfortably clearing Sony’s minimum. It is not the fastest drive here, but for players who simply need more room without spending much, it is a dependable, no-fuss upgrade.
Frequently Asked Questions
Do I really need a heatsink for a PS5 SSD?
Yes. The PS5’s M.2 slot has limited airflow, and without a heatsink a fast Gen4 drive will heat up and throttle during long sessions, causing stutters. Choose a drive with one included or add a low-profile cooler before installing.
Is a 1TB or 2TB drive better for the PS5?
1TB is the affordable entry point and doubles most users’ storage, but modern games are huge, so 2TB is the better long-term buy if you keep several large titles installed and dislike constantly deleting games.
Will any Gen4 SSD work in the PS5?
Almost, but it must meet Sony’s 5,500MB/s minimum read speed, use the M.2 2280 form factor, and fit under the cover with a heatsink. Drives like the SN850P and 990 PRO are guaranteed compatible.
Can I move games between internal and expansion storage?
Yes. Once installed and formatted by the console, you can freely copy or move PS5 and PS4 games between the built-in SSD and your M.2 drive from the storage settings menu.
Final Thoughts
For a stress-free upgrade, the officially licensed WD_BLACK SN850P is the easiest recommendation, while the Samsung 990 PRO earns its keep if you want a drive that shines in both console and PC. Value seekers should look hard at the Lexar NM790 for high capacity or the fanxiang S660 for the lowest cost of entry. Whichever you choose, prioritize a proper heatsink and at least 7,000MB/s where budget allows, and your PS5 will load faster and stay stutter-free for years.
