@westlake: Thanks for the link to the Intel Rapid Storage Technology (RST-VMD) Version 18.2.0.1006 WHQL. I have seen this driverpack on S-D already in the morning and done a look into the files.
Here is my comment:
a) The currently here offered Intel RST drivers v18.1.7.1040/18.31.7.1040 dated 02/26/2021 are newer than the v18.2.0.1006/18.32.0.1006 ones dated 02/18/2021.
b) The related Intel VMD driver v18.2.0.1006 and the Intel RST Installer are missing.
c) These v18.2/18.32 series drivers are the first of a new development branch and may not be free of bugs.
My conclusion: I will wait until the complete Drivers & Software Set (with installer and VMD driver) has been released by Intel.

18.33 can no longer be used on Z370, at least for me.

daniel_k is right - as stated within the start post of this thread, the Intel SATA AHCI Controller DEV_A282 is definitively supported by the Intel RST AHCI driver v18.33.0.1003 WHQL.
I suspect, that you have tried to install the wrong/not matching Intel RST RAID/NVMe driver with the same version. It is clear, that it doesn't work with an Intel SATA Controller, which is running in AHCI mode.

@100PIER:
Your specific problem is obviously caused by the existence of an Intel RAID0 array besides the 2 non-RAIDed Samsung NVMe SSDs and the usage of the latest Intel RST drivers (for details please read the red colored "Warning" text within the "Latest/best Intel RST drivers from the v17 platform:" chapter of the start post). That is why I strongly recommend to set a "Restore Point" before changing the driver of any Storage Controller.

According to my experience this is the easiest and safest way, if the user wants to return to a previously used storage (here: NVMe) driver:
1. Run the Device Manager and expand the "Storage Controllers" section.
2. Right-click onto the listed non-Microsoft Controller (the driver of the Spaces Controller cannot be changed!) and choose the options "Update driver" > "Browse my Computer..." > "Let me pick...".
3. Now the enabled "Show compatible hardware" box will contain a list with the names of all devices, whose drivers have been already previously installed (and are still available for the OS).
4. Click onto the device name, whose driver you want to get used instead of the currently running one, and then onto the "Continue" button (if you are unsure, post a screenshot showing all compatible devices).
5. After the reboot the desired driver for the related Controller will be used by the OS.

Good luck!
