Windows and play on a m.2 ssd?

At the end of the year I'm building a gaming pc

with an nvme crucial m.2 ssd 500gb

I will install Windows and the whole mainbaord graphics card etc drivers and some games

warzone - fortnite

and after 2 weeks I will upgrade to a 480 GB ssd but would it be good or bad to only install 2 games on an m.2 for 2 weeks

please share your opinions and experiences with me

Games on an m.2 SSD are not worthwhile. The differences to a normal SSD are usually only a second or less.
It is best to use the M.2 for the system and programs and a normal sata SSD for the games.
