Microsoft is developing a new NVMe storage driver for Windows 11 25H2 and Windows Server 2025, moving away from the existing storNVMe.sys driver to better align with modern I/O mechanisms. This new driver utilizes the IoRing framework to enhance efficiency by allowing the processor to manage multiple storage requests simultaneously, reducing latency and administrative overhead. Initial tests show significant performance improvements in random read accesses, particularly benefiting applications like databases and virtualization systems. However, sequential access performance may be lower due to ongoing optimizations. The new driver is currently in preview and not activated by default, with practical use limited until further refinements are made.
