It has just been a couple of months since the release of Microsoft’s new operating system i.e: Windows 11 and some users are reporting on various forums about the sluggish performance of their NVMe SSD devices when they are using Windows 11 on their system.
Meanwhile, we found that the reports of the slower performance of NVMe SSDs while using the Microsoft Windows 11 go back a few months and can be found on various Reddit threads and also on Microsoft’s support forums.
The SSD performance issue is particularly affecting random write performance.
The problem here is, the decrease in performance can literally be measured. The image shared by user PleasedPen25317 on Microsoft’s support forums shows the read/write speeds in Windows 10 and Windows 11, a difference of up to 2x and 4X times.
He says his 2TB Samsung 980 Pro NVMe SSDs read/write speed is almost halved on Windows 11 in comparison to Windows 10 operating system.
In another case, a Reddit user named MahtiDruidi has shared a benchmark image comparing the performance of the same SSD running Windows 10 and Windows 11.
Meanwhile, the source of this issue has not been clearly identified but one of the reasons that cause SSD performance drop is said due to the virtualization-based security.
However, the performance drop due to VBS is minimal compared to the difference in SSD read/write speed running on Windows 10 and Windows 11.
Over the past few months, Windows 11 has been affected by a few issues already, including the Intel audio driver issue and critical gaming performance issues. Meanwhile, those issues have been fixed by Microsoft lately.
We believe Microsoft will soon roll out an update to address the performance issues of NVMe SSDs running Windows 11.
