Intel issues, AMD issues, gaming issues and now high performance SSDs. Difficult to do worse in a presentation and also bad publicity if we come from the material limitations that we already saw at the time with the CPU and TPM 2.0. As we say, the latest according to users and Microsoft itself is that your SSD could lose performance, in some cases up to 25% and in the worst of them more than half.
NVMe SSD in Windows 11: goodbye to performance
There are several comments on the popular forums including the one from Microsoft, but the error is so hit and miss (pun intended) that it affects different parts of the SSD in terms of performance. That is, we may not have lost a random read or write, but maybe in 4K crash, or IOPS may drop overall, the diagnosis is not entirely clear.
In addition, the issues are quite localized in terms of performance, but not with SSDs, whether by model or brand, type of NAND Flash or controller, so the search for the problem focused on a very clear section. and concise: the Windows drivers for this type of SSD.
There are more reports apart from these commented out like much higher access time to triple that achieved in Windows 10. In any case, this only seems to affect NVMe PCIe SSD and not SATA, which concentrates the problem much more.
How do we know if we are affected?
It’s a lottery apparently, but based on the fact that we need to know how well we performed in Windows 10 to compare even with a margin of error, the easiest way is to use the usual classic benchmark tests. such as CrystalDiskMark or AS SSD.
As we said, this applies to all NVMe PCIe SSDs on the market including those that have their own driver like Samsung or just those that don’t have SLC cache to speed up performance, it doesn’t seem to matter. for Windows 11.
Microsoft employee Neal Christiansen on Reddit confirmed that the company is investigating the issue, while other users have already started researching the issue on their own like Jeff C, who gave a rather interesting point of view that comes out of the rest. standard, as this ensures that all of your NVMe SSDs will perform incorrectly on Windows 11 while your Intel 905P who has an independent pilot does it correctly.
On the other hand, there are reports with Samsung SSD and Intel itself in other users, so the problem seems quite complex given the variables. So if you noticed something strange on your PC and when checking the speed of your NVMe SSD it is lower than normal then don’t worry, now you know the reason and a fix will arrive shortly, it seems.
