Some s are reporting that ship with bugs of varying degrees of severity. Most companies fixing major bugs in the months following the software release, and that's the reason why big corporations and even certain individuals will hold off updating their operating system to the newest, shiny thing.
It's also why Microsoft is rolling out the Windows 11 update to update to the new OS all at once. Not only does that enable Microsoft to discover and squash early bugs, but it's also a great strategy to prevent their distribution network from crashing thanks to an influx of s eagerly waiting to upgrade.
According to a new report by Neowin, some s are reporting issues with NVMe SSD performance on Windows 11. Compared to the same drives on Windows 10, some s are saying their SSD's write speeds have been halved. While others are reporting their input/output operations per second (IOPS) are lowered. An individual claiming to be a Microsoft employee popped up in a forum thread about the bizarre speed problem and said that he is "investigating this issue," though that's of little comfort to s who are left with no explanation as to what is wrong with their PCs.
No Fix In Sight
At this point in time, it's unclear what's causing the issue as the problem seems to affect s differently between varying machines and SSDs. Even similar machines with the same SSDs don't appear to be having the same slowdowns. One commented saying that their NVMe drive was performing slowly, but using Intel's official driver solved the issue. Whether it's read and write speeds, IOPS, or a driver bug, there definitely seems to be something funky going around with NVMe SSDs on Microsoft's latest operating system. Microsoft has not officially commented or acknowledged that the issue exists.
Of course, that sucks for anyone experiencing the issue, as not everybody has a backup nor the time to restore their PC back to an earlier version of Windows. Unfortunately, at the time of writing, there's no clear answer or resolution at hand. For now, s experiencing slow speeds will have to patiently wait until Microsoft either puts out a statement or releases a patch that resolves the issue. Or, try to resolve the issue on their own.
In a way, this is exactly what Microsoft wanted. Since it's a staggered rollout, only a small number of s, relative to the install base of Windows, are experiencing this issue. Early adopters typically have a higher tolerance for bugs and glitches. And in some cases, early adopters may be able to come up with a solution before the company is even aware of the issue. Sadly, that's not the case this time around.
