Microsoft's new native NVMe driver, initially for Windows Server 2025 but accessible on Windows 11, delivers major performance improvements. Benchmark tests show dramatic gains in random read speeds (up to 64.89%) and significantly reduced random read latency.
The driver also substantially lowers CPU usage during sequential read and write operations, improving efficiency. However, results were mixed for sequential write latency, which increased notably under certain test conditions.
The main topics covered are the driver's performance enhancements in random read bandwidth/IOPS, reduced latency, lower CPU overhead, and specific benchmark results detailing these gains and trade-offs.
