Thank you for posting on the HP Support Community.

After reading your post, I did go through the Product specifications of your product and found that you have 256 GB PCIe® NVMe™ M.2 SSD drive installed on the PC.

See the below table on SSD configuration:

Thank you for your technical support document.

What I'm curious about is how far nvme speed is supported.
800 MB / s is sata speed at x1.
Models supporting nvme x2 speeds range from 1600 to 2000 MB / s.
I think that the nvme model that provides normal x4 should be 3200 ~ 3500 MB / s.

Is it possible that the default speed of nvme m.2 ssd (800 MB / s) provides a limited speed, or 14s-dk0113au does not support x4?

Thank you for the answer.
