Is there a possibility in the BIOS to change from SATA to AHCI after upgrade hard drive to WDSN750.

[Hans_CK]

After upgrading the hard disk to the WD SN750 (NVMe) I wanted to check the setting for the controller in the BIOS and when needed to change from SATA to AHCI. However I was not able to find any setting for the controller in the BIOS. Now the disk is not running to the optimal speed; I think it is about 50% of the possible throughput.

How to proceed? Any tips?

Hi, Hans:

NVMe drives do not use SATA controllers.

AHCI is enabled for SATA disks in the BIOS by default and cannot be changed.

Your WD Black M.2 drive uses a NVMe disk (storage) controller.

Hi Paul,

In other words; no changes possible and no changes needed.

Thank you for your quick reply.

You're very welcome, Hans.

That is correct.

No changes possible and no changes needed.

Look under the storage controllers device manager category and see what NVMe storage controller driver is installed.

It may be possible that WD has a specific storage controller driver for their NVMe drives that you can use in place of the one that Microsoft installs.
