Windows 11
I currently have an Asus Tuf Z390 Gaming Plus motherboard with an Intel Core i7 8700 processor and 32 gb ram. I have a small Adata NVME SSD in the M2_1 slot which was installed by local computer shop on which the OS is loaded. In addition I have an internal Sata SSD and an internal HDD. I have a UEFI bios and am running Windows 11 version 22H2. In the PCH Storage configuration I currently have the option of AHCI or RST, and it is currently set to RST. I am not aware that I have RAID set up, but Speccy mentions that my current Adata NVME RAID Type is Software RAID.

My intention is to purchase a 2tb gen 3 NVME SSD and install it in the M2_1 slot moving the existing Adata SSD to the M2-2 slot. I will do a fresh install of Windows 11 and have already created Windows 11 Installation media on a bootable USB.

I do not fully understand the difference between AHCI and RST. Could someone advise me which setting is best for my proposed configuration, and what other changes if any I should make to my BIOS before installing windows 11. Any further advice for making any other changes would be appreciated.

Thank you.

I have just looked at my BIOS settings and AHCI is enabled, also the M.2 is enabled rather than auto. There are settings for the generation of M.2 slot, my setting is 3, the maximum my motherboard runs at. I think that another of my motherboards has an nvme setting, also. All motherboards have different setup proceedures, there is no standard.

Unfortunately, your motherboard manual doesn't "show" the NVMe settings.
You would need to take a screen shot and post it on here.

    Still assembled, still runs. Haven't turned it on for 15 years?

AHCI vs. RST is really nothing to concern yourself with and will only confuse if you're not aware. At the end of the day, for UEFI, Windows 11 you will want the system in ACHI Mode.

RST is Intel's Rapid Storage Technology used to accelerates drives via supported Optane drives or RAID. If you're not using either there is no need to worry about enabling RST in the BIOS. In keeping things simple unless running Optane memory wanting to use RAID stick to AHCI.


New system build - AHCI or RST Premium? I'm confused!

BTW, Chapter 1, pg. 1-16 of the online owner's manual states STATA ports will be lost depending on which M.2 Port is used....

Choose wisely. And only you know what ports you're using so you will need to decide which one you don't need.
