Finally. I thought it was my idea all along.

I have that KB5007262 update installed since nov 25, but my 980 pro random and sequential didnt change since win11 fresh install, random writes are still lower than my gen3 secondary drive. Sequential has been fine tho, works as advertised since win11 release.

So this issue is addressed on .348?

Win11 with supposed enhanced direct storage capacity vs win10.. :P

So, so far windows 11 is useless tpm and cpu requirements for defender, internet connectivity requirement on installation, less features and crippled GUI, a still unfinished unified GUI, a lot of unreleased improvements, performance issues, final user setting issues, on multiple sides and a lot of missing features, while GOVs around the world are announcing they will not stay with Windows and upgrade to 11...And Nadella is still sitting as a CEO.

That's not relevant to this issue. DirectStorage is a completely separate API that has to be called specifically by programmers. It doesn't affect the OS or any existing software, and nothing has been released that takes advantage of it yet. Its purpose is to allow games and other applications that leverage large data sources (i.e. large high-res texture files) to pull that data at the full speed of the drive rather than going through the normal OS storage engine.
It will, for example, allow games to pull data into the VRAM on your GPU on the fly rather than having to program in a loading system that causes texture pop or having to do a loading screen when you move to a new area. The XBox Series S/X uses it to allow you to swap between games in a couple seconds and give you PC-like performance rather than long periodic loading times (due to the smaller amount of RAM available) like has been seen in the past. It's how an XBSS with 10GB of shared system/VRAM running Halo Infinite can match or beat the load speeds of a PC with 16GB of RAM and 8GB of dedicated VRAM.

they also enhanced the storage stack removing old stuff etc.. but so far..

I guess that their testing process sucks, which we already know - Windows upgrade to new version is still mess, im still getting some Win update for Vista in Win10, which is 5 years failing to install .. Whole UWP mess, i recovered my system drive, to my UWP installed apps on other drives were to synchronized to Windows Apps list.. and it was big mess, there was huge big orphaned games installed, which werent in Apps list so it cant uninstall them to free the space.. and because of UWP delete them was nightware, there is nothing like recheck UWP folders etc.
but its still much better than Linux mess.
Remember DoubleSpace? Microsoft storage drivers team finest creation.. that meant Disk operating system 🙂

2 of my 3 Samsung 980Pro 1TB still suffer the random write issue. C & D drive are affected, E drive isn't, all same 980 Pro 1TB, newest FW. The update is installed since 23rd of Nov. but no change. Luckily it's a dual boot with Ubuntu 😉
from 885k down to 245k random write 4k/32QD on the 980 Pro 1TB
870 Evo 1TB also 75% loss in performance in random write and also random read by 40%.
Still plenty fast for daily computing but for SQL or stuff like that...oh oh MS, what have you done again ?

I just updated to w10 ( year ago ), so another two years im good until then hope they fix most bugs
ultraex2003
test run in my system
win 10 pro vs win 11pro dev 22509
same last samsung drivers with 970 evo

Copy speed is still garbage for me with small files on 970 Evo (Defender & indexer disabled):

It's 2x-3x faster on Linux ext4 with same device and folder. Monster brains @Microsoft, they can't do anything right anymore...
tsunami231
They have brains it just all priorties on add "features" no one asked for or want, instead of making sure thing work correct and or updates dont break things
illrigger
Which features did no one ask for? It's not like they developed this thing in a vacuum - they put in the features their major customers wanted the most, and threw some bones to the consumers. The company I work for pays them a couple million dollars a year in licensing and support. You pay them, what? $100 once or twice a decade tops? Guess who the target audience for their products are?
Kaleid
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)
GamerNerves
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
Kaleid
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.
PrMinisterGR
You seem to have completely missed the point of the post you quoted.
Software development brings new bugs, that's a fact of life.
Kaleid
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.
tsunami231
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
