The Samsung 990 Evo Plus is a 4TB M.2 NVMe drive that runs on PCIe 4.0 x4 or PCIe 5.0 x2, so it fits both older and newer laptops and desktops. Samsung rates it near the top of PCIe 4.0 speeds, with sequential reads around 7,250 MB/s and writes around 6,300 MB/s, backed by a five-year warranty. It suits people who want a big, fast game or project drive without paying PCIe 5.0 prices. Against PCIe 5.0 flagships it gives up peak speed, but it runs cooler and draws less power, which matters in laptops and small builds.
