Why does an SSD sort of cache data?

Question

Solid State Drives

Recently, my SSD, which is already 4 years old, began to cache data. I create a folder on the desktop, but it does not appear, I press F5 and I see this folder with name editing enabled, after entering the name it does not appear and I have to press F5 again. Same thing with files.
This was not the case before. Windows 10. What could be?

Answer 1

Check the paging file in the system properties, in the advanced tab.
