This SSD load problem is pretty damn usual for those who have SSD and Win10 .
It might not be annoying if you don't use your PC for gaming, video editing or any other heavy duty, but if you are, it sucks when game freezes because of 100% SSD load.
Figured out how to fix it and made this video this spring, since than Windows 10 is finally working as it should do.
Just sharing it, it's really short video showing step by step how to end this problem.
