My Crucial has a reported endurance of up to 220TB total bytes "written". Today it has been written 1,3 Tb according to CrystalDiskInfo, but you have to take into account that I cloned my old 1Tb mechanical disk and run lots of speed tests. Mine is the 750 Gb version and if I'm realistic, probably I will run out of capacity before end its lifetime.
I would left the pagefile in the SSD and if you are low on space you can reduce its size.
