The Samsung 990 PRO is a PCIe 4.0 x4 NVMe M.2 2280 internal SSD rated at up to 7,450 MB/s read and 6,900 MB/s write. It is Samsung's top-tier Gen 4 drive, aimed at gamers, content creators and workstation users who want near the ceiling of what PCIe 4.0 allows. Its 4TB capacity and 2,400 TB write endurance put it alongside other premium Gen 4 flagships such as the WD Black SN850X and Crucial T500, which trade small speed differences for similar endurance. Reviews consistently place it among the fastest Gen 4 drives, though it runs warm under sustained loads and needs a heatsink for heavy writes.
