Dual-link PCIe 4.0 x4 and 5.0 x2

The Samsung 990 EVO Plus MZ-V9S2T0B/AM is a 2TB internal SSD built for consumer PCs and laptops. It uses the M.2 2280 form factor and connects through a dual-mode interface that negotiates either PCIe 4.0 x4 or PCIe 5.0 x2 links. The drive runs on the NVMe 2.0 protocol and relies on Host Memory Buffer technology instead of a dedicated DRAM cache.

Sustained throughput with nickel-coated controller

Sequential reads reach up to 7250 MBps and writes up to 6300 MBps, while 4KB random performance tops out at 1000000 read and 1350000 write IOPS. Intelligent TurboWrite 2.0 maintains high speeds across large file transfers. A nickel-coated controller improves thermal efficiency, keeping active power draw at 4.6W during reads and 4.2W during writes for consistent output under load.

Hardware encryption and 1200 TBW endurance

The drive supports 256-bit AES encryption with TCG Opal v2.0 and MS eDrive (IEEE1667) for hardware-based data protection. Rated endurance is 1200 TBW, reflecting the write capacity guaranteed over the product life. Samsung Magician software provides firmware updates and health monitoring to maintain performance over time.

Questions about this item

How much power does the 990 EVO Plus draw during sustained read and write workloads?

The drive consumes 4.6W during active reads and 4.2W during active writes, while the nickel-coated controller helps manage heat without a heatsink.

Does my motherboard need a specific M.2 slot key or PCIe generation to run this 2TB drive?

It fits any M.2 2280 slot and negotiates PCIe 4.0 x4 or PCIe 5.0 x2 automatically; an NVMe-capable BIOS is the only requirement.

Will the 990 EVO Plus work reliably in a laptop that only supports PCIe 3.0?

Yes, the NVMe 2.0 interface is backward compatible with PCIe 3.0 x4 slots, though sequential speeds will be limited to the slot's maximum bandwidth.
