The Samsung 990 PRO is a PCIe 4.0 NVMe M.2 internal SSD built on Samsung's own flash and controller. The 2TB model is rated up to 7,450 MB/s sequential read and 6,900 MB/s write, with random performance about 55% higher than the 980 PRO and up to 50% better performance per watt. It suits gamers, video editors and anyone moving large files who wants near the top of what PCIe 4.0 allows. Against PCIe 5.0 drives it gives up peak speed but runs cooler and draws less power, and it remains one of the fastest Gen4 drives you can buy.

It delivers up to 50% better performance per watt than the 980 PRO. A nickel-coated controller provides thermal control to help avoid performance drops. Samsung makes the firmware and components in-house, including the DRAM and NAND.
Samsung Magician software lets you monitor drive health, protect data and receive updates. To get the full speed, the system must support PCIe 4.0. Speeds were measured with Intelligent Turbo Write active, and actual performance varies with firmware, system hardware and configuration.
