I've got a brandnew SFX14-51G and I wonder how it can be that read speed of the M.2 NVME is slow, abour 3600 MB/s .

I measured it with "winsat disk -seq -read -drive c" command.

The drive is a Micron 3400 MTFDKBAS12TFH. The specification of the drive says its a PCIe 4.0 with max. seq read speed of 6600 MB/s. It is located in the slot that is marked Gen4

    Instead of running the command line, use CrystalDiskMark GUI freeware to measure speeds. Post screenshot of results here if possible.
