Windows 10 and Photoshop CC are not mixing well with the disk usage?

I have recently installed Photoshop CC on my Windows 10 laptop. I noticed my disk usage soaring in the 90–100% range while using PS and I’ve done some searching on how to maintain that usage low to avoid any crashes or overheating.
Anyone that may have done this before I’m sure is familiar with the process, so tell me, is ‘Superfetch’ a service that is not a necessity for my Windows 10 to run effectively? I was going to disable it but I’m unsure if it may interfere with the performance of my computer.
