Key takeaways
- Meet the speed floor: Sony requires at least 5,500MB/s sequential read; drives like the WD_BLACK SN850P clear that bar with room to spare.
- Heatsink is non-negotiable: Choose a drive with a low-profile heatsink or plan to add one, since the PS5 bay has limited clearance.
- Capacity for the long haul: 2TB is the sweet spot in 2026, though 1TB options like the Fanxiang S660 remain a budget-friendly entry point.
- Official licensing: Officially licensed drives such as the WD_BLACK SN850P guarantee fit and cooling, removing any guesswork.
- Value vs peak speed: Beyond the required minimum, extra sequential speed offers diminishing returns for real load times, so weigh price per terabyte.
What's inside
Your PS5’s internal storage fills up faster than ever, and a compatible M.2 SSD is the cleanest way to end the endless dance of deleting and re-downloading games. The console demands a PCIe Gen4 NVMe drive with sequential read speeds of at least 5,500MB/s and, crucially, a heatsink to keep temperatures in check inside that tight expansion bay.
The drives below all meet Sony’s requirements and slot straight into the PS5’s expansion slot. We have gathered officially licensed options alongside proven high-value alternatives so you can expand your library without second-guessing compatibility.

Lexar NM790 2TB

Corsair MP600 PRO LPX
Corsair engineered the MP600 PRO LPX specifically with the PS5 in mind, delivering up to 7,100MB/s reads under a compact low-profile heatsink. Its small form factor is designed to slide neatly into the console’s expansion slot.

Frequently Asked Questions
Does the PS5 SSD really need a heatsink?
Yes. The expansion bay traps heat, and Sony recommends a heatsink to prevent thermal throttling. Every drive on this list either includes one or is designed to fit under a compatible heatsink.
Is 1TB enough or should I get 2TB?
1TB works if you keep a curated library, but modern games are huge. Most players are happiest with 2TB, which greatly reduces how often you juggle installs.
Will a faster drive load games quicker?
Once you exceed Sony’s 5,500MB/s minimum, real-world load time differences are small. Reliability, heatsink fit, and capacity matter more than chasing the highest number.
Are non-licensed drives safe to use?
Yes, provided they meet the PCIe Gen4 speed and heatsink requirements. Licensed drives like the SN850P simply remove any doubt about fit and cooling.
Final Thoughts
Expanding your PS5 storage in 2026 is simple once you match Sony’s requirements. The officially licensed WD_BLACK SN850P is the most reassuring pick, the Samsung 990 PRO is the performance flagship, and the Lexar NM790 delivers superb value. Choose 2TB if you can, make sure a heatsink is on board, and you will never see a full-storage warning again.
