try the samsung nvme driver https://semiconductor.samsung.com/consumer-storage/support/tools/

The actual driver download doesn't suppot the 980 PRO and says so when you try to install it. I tried Samsung magician and it have latest firmware. No resulting change.

So tried windows 10 from standard install media and issue went away. I build an nlite is for my own use and includes the nvme driver from above, this caused the install process to fail when loading that driver.

I installed windows 11 from Ms website and the problem goes away.

Did a full re-intall os 20H2... Same issue... Perhaps 22H2 has fix??

[maverikh]

So I reinstalled atlasos 20h2 on a virtual machine and when the installer ran the data rate wasnear 10k.00 but once os booted... It slowed back down.

I talked with a coworker that does data storage architecture for a living and he thought it is an issue with the way atlasos is reading the onboard controller bus capability. I put in some Samsung 970 PRO nvme drives from my old computer and I installed atlasos... You guessed it my data speed reached the 8k.00 range... I don't think the 970's are as fast but they do support the Samsung driver where the 989Pro does not.

Fixed!!!

Load the samsung inf during pre windows install
