disk benchmarking

About this tag
Disk benchmarking on Windows involves measuring storage performance, particularly for NVMe SSDs. Recent discussions highlight Microsoft's native NVMe I/O path, which bypasses legacy SCSI translation to improve small-block random performance and reduce CPU overhead. However, this client-side feature is unsupported and fragile, suitable only for advanced experimentation. Enthusiasts should approach it cautiously rather than as a guaranteed speed boost. The tag covers topics like SSD benchmarking, NVMe optimization, and Windows storage subsystem changes, with an emphasis on understanding the trade-offs between performance gains and system stability.

    Windows Native NVMe Path: Big Small Block IO Uplift, Not a Universal Win

    Microsoft’s storage team quietly rewired a decades‑old bottleneck: a native NVMe I/O path that bypasses Windows’ SCSI‑style translation and — when enabled — can raise small‑block random SSD performance and cut CPU cost per I/O, but the client‑side route that enthusiasts are using today is...
