Your PS5’s built-in storage disappears faster than you would expect once a few 100GB blockbusters land on the console, and by 2026 the situation is only tighter. A PCIe Gen 4 M.2 drive dropped into the console’s expansion slot is the cleanest way to reclaim that space without deleting your library, and thankfully the market is now packed with drives that hit the speeds Sony recommends.
The catch is that not every fast NVMe SSD is a good PS5 SSD. Sony asks for sustained sequential reads above 5,500MB/s and, crucially, adequate cooling, which is why a heatsink is no longer optional. Below we break down how to shop for the right drive and review the standout models worth installing this year.

Watch: Best M.2 SSD For PS5 2026 — Video Review
How to Choose an M.2 SSD for Your PS5
- Read speed: Aim for a rated sequential read of at least 5,500MB/s; drives like the Samsung 990 PRO at 7,450MB/s give you comfortable headroom above Sony’s floor.
- Heatsink: The PS5 slot runs hot, so pick a drive with a low-profile heatsink already fitted, such as the WD_BLACK SN850P or the Bestoss 2TB, rather than a bare board.
- Capacity: 1TB is the sensible entry point, but 2TB is the sweet spot in 2026 given modern install sizes, and most listed drives here offer that tier.
- Form factor: Confirm the drive is a single-sided M.2 2280 module so it physically fits under the console’s expansion cover without fouling the bay.
- Warranty and NAND: Favor TLC NAND and a five-year warranty, which the MOVE SPEED HB7450 and Acer Predator GM7 both back, for long-term endurance under heavy write loads.
The Best PS5 M.2 SSDs Reviewed
WD_BLACK 2TB SN850P
Officially licensed by Sony, the WD_BLACK 2TB SN850P is the closest thing to a plug-and-play answer. Its pre-installed heatsink is tuned specifically for the PS5 bay, and reads up to 7,300MB/s mean load times are indistinguishable from the console’s native storage. If you want zero guesswork, this is the drive to buy.
Samsung 990 PRO 2TB
The Samsung 990 PRO 2TB is the enthusiast pick, topping out at 7,450MB/s and running with excellent efficiency. Note it ships without a heatsink in this configuration, so budget for a compatible cooler, but the raw performance and Samsung’s endurance record make it a benchmark others chase.
Acer Predator GM7 2TB
Delivering up to 7,400MB/s from a PCIe Gen 4 x4 NVMe 2.0 controller, the Acer Predator GM7 2TB punches well above its price. It doubles as a desktop or laptop drive, so if you upgrade your PC later it will not go to waste. A great value-focused choice.
MOVE SPEED HB7450 2TB
With a bundled heatsink, TLC NAND and rated reads of 7,450MB/s, the MOVE SPEED HB7450 2TB covers every PS5 requirement in one box. Its heatsink profile is designed to clear the console cover, making installation genuinely tool-light and stress-free.
WD_BLACK 1TB SN850P
For players on a tighter budget, the WD_BLACK 1TB SN850P offers the same licensed heatsink and 7,300MB/s speeds as its larger sibling at a lower entry cost. It is the smart pick if you keep a curated library rather than hoarding every title you own.
Frequently Asked Questions
Do I really need a heatsink for a PS5 SSD?
Yes. Sony explicitly requires effective cooling because the expansion slot restricts airflow. A drive with an integrated heatsink like the SN850P prevents thermal throttling and possible shutdowns during long sessions.
Will a slower Gen 4 drive still work in the PS5?
It may install, but if its sustained read falls below 5,500MB/s the console will warn you and performance can suffer. Stick to drives rated at 7,000MB/s or higher to stay safely within spec.
Can I move already-installed PS5 games to the new SSD?
Absolutely. After formatting the drive in the storage menu you can relocate existing PS5 and PS4 titles freely, and you can even install new games directly to the M.2 slot.
Is 1TB or 2TB the better buy in 2026?
2TB is the value sweet spot now that flagship games routinely exceed 100GB. Choose 1TB only if you rotate a small set of titles and want to save money up front.
Final Thoughts
Any of these drives will end your storage headaches, but the officially licensed WD_BLACK SN850P remains the safest all-round recommendation thanks to its ready-fitted heatsink and Sony validation. Bargain hunters should look hard at the Acer Predator GM7, while the Samsung 990 PRO rewards those willing to add their own cooler with class-leading speed.
