Anyone with Wester Digital SN750 that can confirm read speeds?

I recently installed Mojave onto a Western Digital Black SN750 250GB NVMe SSD. I’m a bit confused regarding the read/write speed though, as it’s marketed as doing 1600 MB/s write and 3100 MB/s in read, but I’m getting approximately 850 MB/s in write and 2300 MB/s in read.

Is there anything I’m missing here that needs to be done in order for it to reach it’s full potential? I’ve already set the BIOS to 4x M2 Speed. I’m using the Asus Prime Z370-A II motherboard. Any other settings in BIOS or elsewhere that can be done?
