Key takeaways
- PCIe Gen4 speed rating: Sony requires a minimum sequential read of 5,500MB/s, so verify the drive’s rated speed rather than assuming any NVMe SSD will qualify.
- Heatsink and thermals: A low-profile heatsink is mandatory to fit the bay and prevent throttling; drives that ship with one designed for the PS5 save you guesswork.
- Capacity for your library: Modern games routinely exceed 100GB, so 1TB is a practical minimum and 2TB is ideal if you keep many titles installed at once.
- Physical dimensions: Stick to the 2280 form factor and confirm the heatsink height clears the console cover so the panel closes flush.
- Warranty and endurance: Look at the terabytes-written rating and warranty length; a longer guarantee signals the drive is built for years of gaming installs.

Frequently Asked Questions
Which SSDs are compatible with the PS5?
Any PCIe Gen4 M.2 2280 drive rated at 5,500MB/s or faster with a heatsink that fits the expansion bay will work; check the dimensions before buying.
Do I really need a heatsink?
Yes. The PS5 bay has limited airflow, and without a heatsink the drive can throttle or trigger errors during heavy installs and gameplay.
Is 1TB enough for a PS5?
It helps significantly, but with modern games exceeding 100GB each, 2TB is the better long-term choice if you keep many titles installed.
Will a faster SSD make games load quicker?
Load times are already fast on the PS5, but a compliant drive keeps that speed while adding storage; you will not see slower loads versus the internal drive.
Final Thoughts
The WD_BLACK SN850P is the safest officially licensed choice, while the Samsung 990 PRO and Lexar NM790 deliver flagship speed with the NM790 leading on value at 2TB. Budget-focused players will be perfectly happy with the fanxiang S660 or Bestoss Gen4. Whichever you pick, confirm the Gen4 rating and heatsink fit, and your PS5 library will finally have room to grow.
