Windows Server 2025 Gets Native NVMe SSD Support After 12 Years
18 December 2025 at 02:31
Microsoft has introduced native NVMe SSD support in its Windows Server 2025 build, now available as an opt-in feature for users. After 12 years of NVMe's existence and years of support in the Linux kernel and Linux-based operating systems, native support has been added to the Windows Server stack. Previously, Microsoft converted NVMe drive commands into SCSI commands, which resulted in processing latency and overhead, slowing down read/write speeds in typically high-performing storage configurations. With native NVMe support, the entire stack and I/O processing have been redesigned to achieve optimal SSD performance.
System administrators don't need data to recognize the significant performance improvements that native NVMe support will bring. Windows Server 2025's native NVMe support fundamentally transforms storage performance by enabling direct multi-queue access to modern hardware. It delivers up to 3.3 million IOPS on PCIe Gen 5 SSDs and exceeds 10 million IOPS on HBAs, while reducing latency through streamlined, lock-free I/O paths. This leap in efficiency is essential because traditional SCSI-based processing, originally designed for rotational disks with a single-queue model limited to 32 commands, cannot fully utilize flash storage.
