Question Nvme Speed (Samsung EVO Plus 1 TB) very low

[emark]

Hello everybody,

I just realized that my Samsung 970 Evo Plus 1 TB Nvme shows very low speeds in benchmarks. First I ran a test with Samsung Magician, then an test with Crystal Disk Mark. The results are on Sequential read around 850 MB/s , which I think is very low.
Firmware ist the newest the driver is the samsung official driver, in BIOS is PCIe 3.0 x 4. The Mainboard is a MSI X99A Gaming ProCarbon with an Intel Core i7-6850K, 3800 Mhz with 32 GB DDR4.

Could someone give me hint, where the problem could be? Thank you very much!
