Key takeaways
- Interface and speed: The PS5 requires a PCIe Gen4 M.2 drive with sequential reads of at least 5,500MB/s, so verify the spec before buying.
- Heatsink: A heatsink is essential to prevent throttling in the console’s tight bay, whether built onto the drive or added separately.
- Form factor: Stick to the 2280 size that fits the PS5 slot, and confirm the drive with heatsink still fits under the cover.
- Capacity: 1TB is a solid starting point, but 2TB gives serious players room for a dozen or more large modern titles.
- Licensing and reputation: Officially licensed drives guarantee compatibility, while trusted brands with proven PS5 support are safe alternatives.
What's inside
The PS5’s internal storage fills up fast, and modern games routinely swallow 100GB or more each. Adding an M.2 SSD to the console’s expansion slot is the cleanest way to keep your whole library installed and ready to play, no shuffling required. The catch is that Sony has specific speed and heat requirements, so not every fast drive is a good fit for the job.
To simplify the choice, we’ve rounded up the best PS5-ready M.2 SSDs of 2026, including officially licensed drives, high-speed options with heatsinks, and value picks that still clear Sony’s bar. Below we explain exactly what the PS5 needs from a drive and answer the questions that come up when players expand their console storage for the first time.

Frequently Asked Questions
Do I need a heatsink for a PS5 SSD?
Yes, Sony requires effective cooling for expansion drives. Buy a drive with a built-in heatsink or add a compatible one, as bare drives can overheat and throttle in the enclosed slot.
How fast does a PS5 SSD need to be?
The console requires a PCIe Gen4 drive with sequential read speeds of at least 5,500MB/s. Most quality Gen4 drives comfortably exceed this, but always confirm the rating before purchasing.
Can I run PS5 games directly from the added SSD?
Yes, once installed and formatted, PS5 games run directly from the expansion drive just like the internal storage. You can install, play, and move titles freely between the two.
Is 1TB or 2TB better for a PS5?
1TB adds meaningful space for a modest price, but 2TB is worth it if you keep many large games installed at once. Choose based on your library size and budget.
Final Thoughts
Expanding your PS5 is one of the best upgrades a player can make, and the officially licensed WD_BLACK SN850P is the most foolproof option. The Samsung 990 PRO offers flexibility for those who might reuse the drive in a PC, while the Lexar NM790, Acer Predator GM7, and Inland Performance Plus deliver strong value. Just ensure any drive has a heatsink and meets Sony’s speed bar, and your storage worries are over.
