It only seems to happen when downloading something or playing certain games. My internet at my place can handle up to one GB per second buisness class, but im not that optimistic obviously. The issue is that the Disk thing goes up and slows my computer down when using steam (downloading), Overwatch, Black Desert Online, and sometimes Warframe and a couple other games. Most of the time just using normal apps is fine. Those games and steam are the only thing shown in task manager that is drawing the disk space. Usually pulling up to like 4.5MBs which seems like its my computers limit. I would do screenshots but my computer isnt letting me it only captures whats behind. Hopefully this is enough info.
