With OpenSUSE are you using the open source nvidia driver, or did you add the nvidia hosted repo and install their proprietary drivers?
The nvidia owned repo did work better for me.
But could be memory leak.
For anyone with laptop, and onboard graphics and nvidia RTX I had to install an opensuse swicher package to ensure appa start on the right GPU (right click option on the app) I forget the app name at the moment, it wanst the bumblebee or optimus, it was something else, Switcheroo maybe.





Hardware raid is fine as long as you can still get the same hardware RAID card or Motherboard.
