I don't understand this post. Windows had native NVMe support since Windows 8.1 (and Windows 7 with a patch applied). Since Windows Server is based on the same codebase, Windows Server 2008R2/2012R2 onwards had support too. I can install Windows 11/Windows Server 2025 on a NVMe drive today and get full speed no problem. 

Can someone explain this for me? Is that any different than what we already have today? I'm lost...

It supports, but is not native; it's like a translation layer from NVMe to SCSI.

For example, if you search for 'Device Manager' in the Windows Start menu (Or Windows + X>Device Manager) and open 'Storage Controllers' or 'Disk Drive', then go to 'Details' > 'Driver Class', the 'Value' will appear as 'SCSI Adapter'.

On the other hand, if Win 11/Server has the 'fix' for NVMe enabled, it will appear as 'NVMe Disk'.

    Oh, got it! I appreciate your explanation, RozinhaK. 

    Knowing that makes me wonder why MS wouldn't implement NVMe support properly when it debuted on the OS 12 years ago. This company relies too much on legacy tech, even when it could start on the right track from the beginning. Sad!
