Since March this year, users have reported that Windows 11 has NVMe SSD performance problems, and subsequent cumulative updates have not improved. Some users claim that their SSD speed has decreased by more than 50%.
While Microsoft has never acknowledged the issue, based on feedback from Window’s Latest users, the issue has been resolved with the latest update.
The following is a list of affected Windows updates:
- KB5028185 – July 2023 Patch Tuesday update (mandatory update).
- KB5027303 – June 2023 optional update.
- KB5027231 – June 2023 Patch Tuesday update (mandatory update).
- KB5026372 – May 2023 Patch Tuesday update (mandatory update).
- KB5025239 – April 2023 Patch Tuesday update (mandatory update).
- KB5023778 – March 2023 Patch Tuesday – This issue was first reported after this update, and KB5023706 is also affected.
At the same time as the Windows 11 preview.
Since the KB5023778 update in March 2023, users have often reported SSD performance issues and a large number of users now report that Win11 has shown a significant improvement after the latest update.
One user said, “In the DevOps world, I/O performance is critical. Since the March update, it’s been like driving a sports car with a gas jam. The most recent August update fixed it for us NVMe SSD issues, but it also opened our eyes to the need for Microsoft to improve their quality assurance processes. Also, thanks for tracking this issue to us, Mayank”.
Another user told Windows Latest, “I manage a fleet of devices and have had noticeable SSD sluggishness since the March update. I had to improvise a third-party solution to keep things going. Now, with Now that the August update has been fully deployed, I’m seeing consistent disk performance across our devices. Thanks for the fix, but it’s a reminder of how important it is for us to test thoroughly before rolling out any software updates.”
