Slow SSD NVMe speed

[tarmiricmi]

Hello,
I have a HP Notebook -15-db1041nm, specs here.

It supposedly has a NVMe m.2 SSD, Kioxia KBG40ZNV256G. Actual picture of the disk inside here.

That SSD apparently gives this performance (ca. 1900 mbs read/ 1100 write).

I tested it with Crystal Disk Mark (latest version, default settings), and got this result (450/380 mbs).

This result is far away from the specifications. It resembles something that is SATA standard, not NVMe m.2 SSD.

The laptop is bought a year ago but it sits on the shelf without usage. Everything functions fine, no issues, all drivers updated to their latest with the HP Support Assistant. The BIOS doesn't have any settings regarding storage, other than boot order.

The issue here is that either the disk or controller works in PCIE 1.0 x2 mode, as presented here:

Any ideas?
