The performance of NVMe SSDs in Windows 11 have dropped significantly

Users recently reported performance problems with Windows 11 solid-state drives on Microsoft’s official forums, and NVMe solid-state drives were mainly affected.

The read and write speed of NVMe SSDs are much better than that of SSDs or mechanical hard drives with SATA interfaces. The system performance can also be significantly improved thanks to high-speed read and write.

The performance problems found by users are compared with Windows 10. The test found that the same solid-state drive performs poorly on Windows 11.

However, there are some differences in the specific problems found by users. Some user tests found that the performance of random read and write decreased, and some user tests found that the speed of sequential reads and writes decreased.

A professional user conducted a test and found that most solid-state drives use general-purpose drivers issued by Microsoft, which are usually built into the system and do not need to be installed separately.

The performance degradation of the solid-state drive uses the universal driver issued by Microsoft, and the performance of the driver issued by the hard disk manufacturer itself does not affect the performance.

The user test found that the Intel 905P solid-state drive uses Intel’s signature driver, and the performance of this solid-state drive has not declined after comparative testing.

At the same time, the user tested the performance of the Microsoft universal drivers used by several other solid-state hard drives. Is this a problem with the drivers developed by Microsoft?

In the Windows 11 Feedback Center, users also reported similar situations, including decreased peak write performance, increased IOPS latency, and halved random write speeds.

Neowin using Western Digital SN520 for testing really reproduced the problem. It is almost certain that Windows 11 will have some impact on NVMe SSDs.
