The assorted Optane solutions had flash of popularity when the 32-64 GB SSDs were used as cache drives in conjunction with a much larger spinning drive.
I would abandon all references to it for home users considering it as cache drives, and, opt for a decent NVME drive as the OS drive alone if your mainboard supports it. (SATA drives, available in standard 2.5" SSD and in M.2 packaging, generally a waste of an NVME slot) operates at much slower speed spec (about 550 MB/sec reads/writes, max), you can add one after the OS install as a secondary storage drive for games and apps (if you don't have a lot of games, and have plenty of NVME space, then install whatever to the NVME drive for best of all worlds. (Use the SATA SSD where you don't want to fill up the NVME drive, don't mind waiting 1-2 seconds longer for apps/games to launch/open/load, vice the 'watching paint dry' torture that occurs using spinning drives for same.
