Windows Server 2025 + S2D (Storage Spaces Direct) + Micron 7450

Hi, I've been trying about a thousand different combinations of Windows Server Datacenter 2025 preview with Micron 7450 Pro NVMe SSD drives, and I just can't get Windows to report these correctly.


I'm starting to think it's a bug in Windows.


So first off, these drives definitely have PLP (power loss protection).  They're enterprise NVMe SSD drives.  And as far as I can tell, they are compatible with S2D.

But no matter what configuration I do from both hardware and software, the "Cluster Validation Report" for S2D says the "Disk does not have non-volatile cache."  Here's two screenshots - one using Window's driver, and one using Micron's driver:






I'm at a loss.  Is this a Windows 2025 bug?
