Windows 11 would slow down some SSDs
It’s been two months since Windows 11 was released to users, but the operating system has had its fair share of bad publicity, especially when it comes to performance. And now reports are emerging that the operating system is slowing down some SSDs.
A thread on the Microsoft community forums, spotted by Neowin, has complaints from several users who say their SSD performance deteriorated significantly after upgrading from Windows 10 to Windows 11.

Users shared screenshots that show benchmark results from drive measurement tools like CrystalDiskMark, Samsung Magician, and more. You can tell just by looking at the pictures that there is a problem. Screenshots reveal that random write speeds have halved in Windows 11, compared to benchmarks taken on Windows 10.
Interestingly, the majority of these complaints have one more thing in common, the problem seems to be widespread among Samsung NVMe SSD users. Some comments on the forums indicate that the issue does not affect Intel Optane SSDs.
Another theory excludes the possibility that VBS (Virtualization Based Security) affects performance, since the option was disabled before taking the benchmark. Some users have claimed that turning off the option has improved their system speed, you can optionally try it by going to Windows Security> Device Security> Primary Isolation and toggle the Memory Integrity setting. You can also turn off animation effects in the accessibility options in the Settings app.
Other threads posted on the Microsoft Feedback Hub and on Reddit have many users discussing the issue. This problem has not appeared yet, it seems to have existed for about 3 months. That’s long before Windows 11 was released, which means Microsoft didn’t fix the issue while the operating system was in the preview phase and shipped it as is. Users appear to be on the operating system’s stable channel, and the consensus is that there is a bug in Windows 11 that affects the performance of SSDs. It is either that or some bad drivers that are causing the problem.
Some users say that the recent Windows update KB5007262 (which is a preview update) has improved the performance of their computer. If you are having similar issues, maybe this is something you could try.
My computer does not have an NVMe SSD, and I also have no benchmarks to compare the result with, but I can understand that such massive degradation in performance can be frustrating. Although I have no problem running games on my computer, I have noticed that Windows 11 is slow in some areas, for example the file explorer or the context menu on the desktop, sometimes the files take a fraction seconds longer than they should to open. There is a very noticeable lag in both situations, in what was an otherwise smooth experience in Windows 10. A friend of mine restored his PCs to Windows 10 after realizing his system was slower, but more importantly due to some incompatibilities with Visual Studio.
Performance issues might deter users from upgrading from Windows 10 to 11, you can’t fault them for wanting to stick with proven software. Microsoft must fix this if it hopes to convince more users to adopt the new operating system.
How is your SSD performing on Windows 11?
