Good stuff. Gran stuff. Let it be used. 🍋
After Microsoft released a new driver specifically designed for use with NVMe-style SSDs, it resulted in a marked improvement in Storage system performance on Windows Server 2025, despite the feature being designed primarily for enterprise use.
.
But the average user can use Windows 11 as well, but this feature may have to be extracted through a slight Registry revision, which results are considered interesting.
.
There were X Names Mouse & Keyboard users tested on Windows 11 25H2 in combination with a 2TB SK hynix Platinum P41 version using the AS SSD Benchmark program. The total score was found to increase from 10,032 to 11,344, or about 13%. Specifically, Random Write performance at 4K and 4K-64Thrd events increased by 16% and 22% respectively.
.
Meanwhile, a Reddit user named Cheetah2kkk tested it on a Claw 8 AI + machine that upgraded a 4TB Crucial T705 sample force. Despite the slight increase in sequential speeds, Random Performance has increased markedly. Random Read speeds have increased by around 12%, Random Write has increased by up to 85%, in line with Microsoft's goal of increasing IOPS and reducing Latency.
.
The centerpiece of this change was the reworking of Windows as the system often instructs SSD NVMe to work in the same way as traditional SCSI devices, which is an idea from the HDD era and has more complex procedures. This new NVMe driver eliminates unnecessary command conversion procedures, reduces system load, and unlocks the potential of NVMe more.
.
However, this feature is still designed primarily for servers. Tasks like Database, Virtualization or AI are much clearer than in general use. SSD management software from many camps is still not fully supported. The key question now is when Microsoft will officially bring this new NVMe driver to the common version of Windows after more than 14 years of waiting.
