Microsoft acknowledges slow NVMe SSD write speeds in Windows 11 - working on a fix.

Microsoft acknowledges slow NVMe SSD write speeds in Windows 11 - working on a fix.

Windows 11 has had a bug for a long time that slows down the write speed of hard drives and SSDs. Microsoft is releasing a fix for the problem under patch  KB5007262. 

Recent tests by Reddit user PleasedPen25317 showed that the random write speeds of the Samsung 980 Pro SSD went down a lot when Windows 11 was installed on any partition that had the SSD. It must have been more widespread than previously thought because the problem affects all drives, not just NVMe SSDs, which are very, very fast.

 

November 22, 2021—KB5007262 (OS Build 22000.348) Preview - 

Addresses an issue that affects the performance of all disks (NVMe, SSD, hardisk) on Windows 11 by performing unnecessary actions each time a write operation occurs. This issue occurs only when the NTFS USN journal is enabled. Note, the USN journal is always enabled on the C: disk.

Read more about it here, a whole lot more has or will be fixed.

Yes, we know it's not the same. It's just that there is a difference between what is marketed and with what is delivered. They didn't even properly benchmark Ryzen CPUs. A major rich company is often a major screw up. That's been observable for decades.
(Yes I know OS are complex and contains a amounts of code but they do not lack the resources to test things before bringing them out)

Resources do not mean that you can just bring a mass of people to solve any problem and call it a day. If the issue is complex, it doesn't matter that much if there is 100 versus 5 people investigating it, because at least one person needs to fully understand the whole structure of the issue first, since we are talking about code here. Organizing even few people to research the issue at hand effectively is the best solution and in fact the only working one instead of throwing money into the air. Heck the problem could even be that they have too much staff doing the same thing and switching places so nobody knows exactly what is going on, but this is just me thinking, I really don't know. Resources can solve problems quickly, but not nearly everything.

EDIT. added some

They can easily afford to hire hundreds of experts in several areas if needed. They just don't really care that much. They are so competent that they manage to invent new bugs where there haven't been before.

You seem to have completely missed the point of the post you quoted.

Software development brings new bugs, that's a fact of life.

What point? Was it complex to fix the AMD error? Was it complex to find it during pre-release versions and working on fixing it before release?
Of course new bugs are introduced, but yet again you'd think that a major company with the manpower has the ability to iron them out before release.
It's not like their finances depend on getting Win11 out at the date they had set. The even announced Win11 rather late, very few actually expected a new OS from them and certainly not this year.

And it's not that they only create new stuff, they tend to make every version just a bit dumber, just a bit worse especially for the power users.

from my understanding they knew about it also had fix for insiders, but RTM verison didnt have fixed included and wasnt for some time? wasnt it even fixed on insiders before RTM was even released? update bring bug all the time, I should know Roku update on my tv keep breaking same thing over and over. luckly the last update fixed it all again

I do agree with there making thing dumber and worse for power users
