What reviewers say
Samsung 990 PRO NVMe SSD 1TB
Owners rate the 990 PRO highly for real-world speed and reliability, and it is a common pick for gaming builds and PS5 upgrades. Complaints center on heat under sustained writes and the price premium over cheaper PCIe 4.0 drives.
- SpeedPraisedOwners say boots, game loads and large file transfers feel much quicker than older drives.
- HeatCriticisedSustained writes push temperatures up, and users recommend a heatsink for heavy workloads.
- ReliabilityPraisedLong-term owners report few failures and consistent performance over time.
Questions and answers
- Which is better for a PS5?
- Both work in a PS5. The 990 PRO 1TB is the stronger pick for speed and endurance, but it needs a heatsink. The P310 is cheaper and comes in a non-heatsink design, so add one too.
- Which fits a Steam Deck?
- Only the Crucial P310. Its M.2 2230 version fits the Steam Deck and similar handhelds. The 990 PRO is M.2 2280 only and is too long.
- Is the 990 PRO worth the extra money?
- Yes if you want 1TB, DRAM cache and higher endurance for a main PC or PS5. If 500GB is enough or you need a 2230 drive, the P310 saves money.
- Which lasts longer?
- The 990 PRO. It is rated at 600 TBW with a 5-year warranty. The P310 has a low TBW rating for its capacity and a DRAM-less design.
- Which is faster?
- The 990 PRO is slightly faster on paper, at 7,150 MB/s read and 6,450 MB/s write versus up to 7,100 MB/s and 6,000 MB/s. The bigger gap shows in sustained writes, where the DRAM cache helps the 990 PRO.
