The Samsung 990 PRO is a PCIe 4.0 NVMe drive in the M.2 2280 form factor, rated at up to 7,450 MB/s read and 6,900 MB/s write with 2,400 TBW of endurance. It uses Samsung's own V-NAND TLC, in-house controller and 4GB LPDDR4 cache, and hits 1,600K/1,550K IOPS random read/write. It is one of the fastest PCIe 4.0 drives made, so it suits gamers, editors and anyone moving large files who has a PCIe 4.0 x4 slot. Against PCIe 5.0 rivals it gives up peak speed but runs cooler and draws less power; against budget PCIe 4.0 drives it costs more but holds speed better under sustained load. It ships as a bare drive with no heatsink.

Owners and reviewers rate the 990 PRO as one of the fastest and most consistent PCIe 4.0 drives, praising its near-advertised speeds and sustained performance. Complaints center on heat under heavy writes without a heatsink and on the premium over cheaper drives.
The Samsung 990 PRO 4TB is an internal PCIe 4.0 NVMe SSD in the M.2 2280 form factor. It is rated for up to 7,450 MB/s sequential read and 6,900 MB/s sequential write, with an endurance rating of 2,400 TB written.
It uses Samsung V-NAND TLC, a Samsung in-house controller and a 4GB LPDDR4 cache. Random performance is rated at 1,600K IOPS read and 1,550K IOPS write. It is a bare drive with no heatsink.
It needs a free M.2 2280 slot or bay and PCIe 4.0 x4 support on the board. A drive runs at the speed of the slot it sits in, so in an older slot it works at that slot's speed.
