Guess you will get a better performance. Had my sim installed on a 500gb 970evo pci3 which was 80% filled.
So I bought a 1tb 980pro pci4, switched the sim to that nvme and left the Rolling Cache on the old one.
I guess it’s a little more smoothness compared to my previous configuration. So I would believe that a change from a SATA SSD to a nvme SSD will be an advantage as well
