Key takeaways
- Speed requirement: Sony recommends a minimum sequential read of 5,500MB/s, so target Gen4 drives rated at 7,000MB/s or higher for comfortable headroom.
- Heatsink: The PS5 needs a heatsink to prevent thermal throttling; choose a drive with one pre-installed or budget for a separate low-profile cooler.
- Form factor: The console requires the M.2 2280 size, so confirm the drive length matches before buying to ensure it fits the expansion slot.
- Capacity: A 1TB drive roughly doubles usable space, while 2TB is the sweet spot for players with large libraries who rarely want to delete games.
- DRAM and endurance: Drives with DRAM cache and higher TBW ratings tend to hold performance and longevity better under sustained gaming installs.
What's inside
The PlayStation 5’s built-in storage fills up fast, and with modern games routinely topping 100GB, adding an M.2 SSD is one of the smartest upgrades a console owner can make in 2026. The good news is that expansion has never been easier or more affordable, with a wide range of Gen4 drives that meet Sony’s speed requirements and slot straight into the console’s expansion bay for near-instant load times.
Not every fast SSD is a good PS5 match, though. The console demands sequential read speeds of at least 5,500MB/s and a compatible heatsink to avoid throttling, so choosing the right drive matters. This roundup rounds up the best M.2 SSDs for the PS5, from officially licensed options to high-value performers that deliver console-ready speed without overspending.
