When it was first cloned yes, but then I got rid of redundant programs. Left VR games and photo/video editing programs on m.2 , uninstalled the rest. On the old drive, uninstalled the ones I left on m.2 and left the rest. Any new programs have been installed on the old. The only similarity between the two now is both have Windows 10. Trying to decide which is worse with regards to the old drive - the wasted space taken up by Win10 or the headache of formatting and reinstalling everything. I started this project because I’m tired of having all these int/ext drives with redundant files and mixed file types. I’m setting it up so C is the m.2 with OS and a few select programs, the old will be all other programs. And then separate drives for photos/videos, documents, and music. Then properly backup.
Thank you for the suggestion.
