I found out about 2 months ago I had a dead stick because of my Arch install. I kept having data integrity problems and thought my NVMe was dying. And then the other drive was having the same issues. I had reinstalled Arch so many times during this that I memorized ALL the steps from start to end. I really wish I had tested RAM earlier, but was so determined to believe it was the drives.

At least you have a lot more experience with installing Arch now. Might be usefull when you want to install it on other PC’s.
