Key takeaways
- Interface and speed: The drive must be PCIe Gen4 M.2 2280 with sequential reads of 5,500MB/s or faster to satisfy Sony’s minimum requirement.
- Heatsink: A pre-installed low-profile heatsink prevents thermal throttling and fits under the console’s cover, saving you from sourcing one separately.
- Capacity: 1TB is the practical entry point, but 2TB gives far more breathing room for a modern library of large titles.
- NAND and endurance: TLC NAND with a healthy DRAM or SLC cache sustains speeds better during large installs than budget QLC alternatives.
- Physical fit: Confirm the heatsink height clears the expansion bay, since some oversized aftermarket coolers will not fit the PS5 slot.
What's inside
The PS5’s internal storage fills up fast, and in 2026 modern games routinely demand 100GB or more each. Adding an M.2 SSD to the console’s expansion slot is the cleanest fix, letting you run games directly from the new drive without shuffling titles back and forth. But Sony’s speed and thermal requirements mean not every fast NVMe drive is a safe bet.
To qualify for the PS5 a drive needs PCIe Gen4 speeds of at least 5,500MB/s and effective heat dissipation, which is why a heatsink is strongly recommended. We focused on drives that meet or exceed those requirements while balancing capacity and price. Below are the best M.2 SSDs for the PS5 this year, followed by the criteria that keep your expansion trouble-free.

The Best M.2 SSDs for PS5 Reviewed
WD_BLACK SN850P 2TB
Officially licensed for the PS5 and rated up to 7,300MB/s with an included heatsink, the SN850P is the plug-and-play safe choice. It is validated for Sony’s requirements out of the box, so if you want zero guesswork this is the drive to buy.
Samsung 990 PRO with Heatsink 2TB
The 990 PRO is a performance benchmark, hitting up to 7,450MB/s reads with a heatsink sized to fit the console. It pairs top-tier speed with Samsung’s proven reliability, making it the enthusiast pick for a fast, spacious upgrade.
Lexar NM790 2TB
Rated at 7,400MB/s reads and shipping with a heatsink, the NM790 delivers flagship-class speed at a friendlier price point. It is the value standout for gamers who want 2TB of fast storage without paying a premium badge tax.
Acer Predator GM7 1TB
The GM7 offers Gen4 speeds up to 7,400MB/s in a 1TB capacity, making it a strong mid-range option. It is well suited to players who want a fast expansion drive but do not need the full 2TB just yet.
fanxiang S660 1TB
With a bundled heatsink, PS5 compatibility, and an SLC cache, the S660 targets budget-conscious buyers. It trades peak sequential numbers for affordability, and is a sensible entry-level pick to double your storage cheaply.
Frequently Asked Questions
Do I really need a heatsink?
Yes. The PS5 slot can get hot, and without a heatsink a high-speed drive may thermally throttle or trigger warnings. A pre-installed low-profile heatsink is the safest route.
Is a 5,500MB/s drive fast enough?
That is Sony’s stated minimum, and drives at or above it work fine. Faster drives exceed the requirement comfortably, which provides headroom rather than a dramatic real-world speed difference in most games.
Can I move PS5 games to the M.2 drive?
Yes. Once installed and formatted, the drive appears in storage settings and you can install and play PS5 games directly from it, or move existing titles over to free internal space.
Should I choose 1TB or 2TB?
If your budget allows, 2TB is the better long-term value given how large modern games have grown. 1TB is fine for a smaller, curated library that you rotate regularly.
Final Thoughts
For a foolproof PS5 upgrade, the officially licensed WD_BLACK SN850P is the easiest recommendation, while the Samsung 990 PRO delivers the highest headline speeds. Budget-minded gamers will find the Lexar NM790 and fanxiang S660 hard to beat on value. Confirm Gen4 speeds and heatsink clearance, and your console will feel new again.
