PS5 requires: M.2 NVMe SSD, PCIe Gen 4 (or Gen 3 with 5,500+ MB/s speeds), 5,500 MB/s minimum read speed, 250GB to 4TB capacity, 2280 form factor (2230-22110 supported), and maximum dimensions of 110mm x 25mm x 11.25mm (including heatsink). Sony strongly recommends using a heatsink to prevent thermal throttling during extended gaming sessions.

The Samsung 990 Pro is the fastest PS5 SSD with 7,450 MB/s speeds. The WD Black SN850X offers similar performance with excellent gaming optimization. For best value, the Crucial T500 matches flagship speeds at lower prices. Budget pick: WD Black SN770 meets PS5 specs at entry-level pricing. All deliver identical in-game load times — choose based on price and capacity needs.

Yes, a heatsink is strongly recommended. PS5's SSD bay has limited airflow, and NVMe drives can throttle when they overheat. Many SSDs (990 Pro, SN850X, T500) offer versions with pre-installed heatsinks designed for PS5. If buying a bare drive, add an aftermarket heatsink — ensure total height stays under 11.25mm. Some users report drives working without heatsinks, but Sony recommends one for optimal performance and drive longevity.

2TB is the sweet spot for most gamers — enough for 20-30 modern games alongside the internal 667GB usable. 1TB works for budget-conscious buyers or those who rotate fewer games. 4TB is maximum supported — great for game collectors who want everything installed. Consider that PS5 games average 50-100GB each. The internal drive + 2TB expansion gives ~2.5TB total, usually sufficient for most players.

Both are excellent, and real-world PS5 game load times are virtually identical. The 990 Pro has slightly faster sequential speeds (7,450 vs 7,300 MB/s) and better power efficiency. The SN850X sometimes edges ahead in random read benchmarks. Choose whichever is cheaper at the time of purchase — you won't notice any difference in actual PS5 gaming. Both offer heatsink versions designed for PS5.

Yes, Gen 5 SSDs work in PS5 but run at Gen 4 speeds since PS5 only supports PCIe 4.0. Gen 5 drives like the Crucial T705 or Samsung 990 Pro with Gen 5 support are backwards compatible. However, you're paying extra for speeds you can't use on PS5. For PS5, stick with Gen 4 drives (990 Pro, SN850X, T500) which maximize the console's capabilities at lower prices.

Installation is straightforward: 1) Power off PS5 and remove the base. 2) Remove the cover (slide it off). 3) Remove the expansion slot cover screw. 4) Insert SSD at an angle into the M.2 slot. 5) Press down and secure with the screw (move spacer to match SSD length). 6) Replace covers and boot PS5. 7) PS5 will prompt you to format the drive. The whole process takes 5-10 minutes with a Phillips screwdriver.

No — PS5 games must run from internal storage or the M.2 expansion slot. External USB drives can only store PS5 games (not play them) and play PS4 games directly. Strategy: use external USB for PS4 games and storage, use internal + M.2 SSD for PS5 games. You can move PS5 games between internal and external storage, but they must be on internal/M.2 to play.
