The Samsung 990 EVO Plus is a 4TB M.2 2280 NVMe drive that runs PCIe 4.0 x4 or PCIe 5.0 x2 and is rated up to 7,250 MB/s read and 6,300 MB/s write. It uses Samsung V-NAND TLC with an in-house controller and works with Samsung Magician for monitoring and firmware updates. It is a capacity-first drive: the 4TB model is the point, and it fits desktops and laptops with an M.2 2280 slot. Against premium Gen 4 drives like the 990 Pro it trades some random-write speed and endurance for capacity and efficiency; against budget QLC drives it keeps TLC and steadier sustained writes.

Owners treat the 990 EVO Plus as a reliable, efficient drive that delivers near-advertised sequential speeds and runs cool in normal use. Enthusiasts note it trails the 990 Pro under sustained heavy writes and lacks a DRAM cache.
