I’m not entirely sure why you went with 2 1TB NVMe drives.
I have two NVMe drives plus a slow HDD in my gaming PC so I can keep my games on fast storage without having to reinstall them whenever I install a new distro. I know I could have accomplished this with separate partitions, but every installer is a little different and I just cannot be arsed to re-learn how to do it every time. I sprung for the extra 1 TB stick ($50 or so), and now I don’t have to spend hours googling and watching youtube tutorials whenever I want to install a new distro—I just let the installers blow away the entire OS drive and do their thing.
