My drive structure is like that.
I have one drive for digital images and video backup.
One drive is a copy of that. double backups are always good.
I really only use 3 drives for programs, One for legacy programs , not much running on that. One is for current programs, then my c windows drive has some smaller programs that constantly run.
Today I noticed that my regular ram is about half, and virtual ram is about 80% usage.
Started a high demand game and went up to 90%.
I will try shifting as suggested and see how it goes.
Over the past few days I have played games and high demand , had a few lag spikes but it evened it out.
Right now my c drive has 202 gb free.
I am considering going to a 2 TB drive or a 4, but moved some files to storage drives cleared up some room. ( extra desktop stuff that didnt need to be there)
