Our take on the Samsung 990 PRO 4TB

The Samsung 990 PRO 4TB is a high-end PCIe 4.0 NVMe SSD built for fast gaming, large file transfers, and heavy workloads. It delivers sequential reads up to 7,450 MB/s and writes up to 6,900 MB/s, with random performance of 1.6M read and 1.55M write IOPS. The 4TB model offers a huge 2,400 TBW endurance rating, double that of the 2TB version, making it suitable for write-intensive tasks. Reviewers praise its speed and reliability, though some note that PCIe 5.0 drives now offer higher peak speeds. It suits gamers, content creators, and professionals who need fast, durable storage.

Questions and answers

Is the 990 PRO 4TB compatible with PS5?
Yes, it meets the speed requirements, but you will need to add a heatsink to fit the PS5's expansion slot.
