WD 750SN Black - Slow speeds


I just installed my new WD750SN Black and did speed tests which were like 35% of expected.
Speed test: Speed test

I reinstalled my windows 10 twice setting up AHCI in BIOS.
It was the only one disk during windows installation.
I attached it to my m.2 port but I also tried to connect it using pci express adapter.
I was using western digital ssd drivers, intel drivers.
I was trying almost everything but the speeds are still double slower than my 3 years old Toshiba ssd disk.

My Desktop details:

BlockquoteMachine Alienware - Alienware Aurora R7
Operating System Microsoft Windows 10 Home (64-bit)
Memory 16 GB
Processor Intel® Core™ i7-8700K CPU @ 3.70GHz
Motherboard Alienware - 0VDT73
Video Cards Intel® UHD Graphics 630
Hard Disk ST1000DM010-2EP102 (1.0 TB)
Network Card Killer E2500 Gigabit Ethernet Controller

I would be grateful for some ideas, drivers, anything to fix it.

Thank you for any advise.

Does the system have an intel optane module?

You’re quite silent … Problem solved?
