Manufacturer description

The Samsung 990 EVO Plus is a 1TB NVMe M.2 SSD built around a flexible dual-interface design: it runs on PCIe 4.0 x4 or PCIe 5.0 x2, so it slots into current gaming desktops and newer thin laptops alike. Sequential read speeds reach up to 7,150MB/s, which shortens level loads, shader compilation, and large project transfers compared with older Gen3 drives. Intelligent TurboWrite 2.0 widens the SLC cache dynamically, helping sustain write throughput when you dump a 100GB game install or a folder of raw footage onto the drive. Samsung also rates this generation at 73 percent better energy…

Frequently Asked Questions

How fast is the Samsung 990 EVO Plus 1TB?

Samsung rates sequential reads at up to 7,150MB/s. Write speeds vary with the Intelligent TurboWrite 2.0 cache state; check the product listing for the rated sequential write figure.

Will this SSD work in a PCIe 5.0 motherboard?

Yes. The 990 EVO Plus supports both PCIe 4.0 x4 and PCIe 5.0 x2, so it operates in Gen4 and Gen5 M.2 slots without a separate adapter.

Does the 990 EVO Plus come with a heatsink?

This MZ-V9S1T0BW listing is the bare M.2 2280 drive with Samsung's intelligent thermal solution built in, not an add-on heatsink. Verify the exact variant on the product page before ordering.

Is 1TB enough for gaming, or should I get a larger size?

1TB holds Windows plus roughly 8-12 modern AAA installs. The 990 EVO Plus family scales to 4TB, so you can add a second drive later if your library grows.

Do I need Samsung Magician to use this drive?

No, it works as a standard NVMe drive out of the box. Magician is optional software for firmware updates, drive health checks, and performance tuning.
