Does adding Intel Optane make sense when 512G Intel NVMe SSD is in the m.2 slot?
Solution 1:
Optane is, I believe, a fancy name for fast SSD used for caching. There is little point in adding it to your system as your SSD is very fast and pretty similar in effect- see https://community.intel.com/t5/Solid-State-Drives/Acceleration-of-new-670p-using-intel-optane-memory/m-p/1276119
If I had money to burn on Optane in this case I'd throw it at more memory instead.
