What’s New: Truly Native NVMe in Windows
Microsoft’s new NVMe driver—introduced in Windows Server 2025 and exposed experimentally in Windows 11 25H2—removes SCSI from the equation entirely.
What changes under the hood?
- NVMe is handled end-to-end as NVMe
- No SCSI translation layer
- Direct NVMe command submission
- Better scaling at high IOPS and queue depths
- Significantly reduced CPU overhead
Microsoft is calling this an architectural shift, not a simple driver update—and that distinction matters.
