I've been noticing some performance issues where neither RAM nor CPU usage appear to be the bottleneck. At most, on any given day, I'm only using half of my 8GB of RAM and maybe 20% of my CPU. What I am noticing, however, is that lagging is always accompanied by Disk usage being at 100% (in task manager). When I look at the transfer rates, it runs into 100% Disk at around 5-10MB/s, which seems awfully low. The computer can achieve 15-20% Disk when idling and 100% when performing very basic tasks. I believe the performance issues clearly have something to do with writing/reading to/from my hard disk, but I'm not sure what the issue is. Should I expect to regularly hit 100% Disk? Any help would be greatly appreciated.
To be a little more clear, I'm trying to figure out why so little reading/writing speed is causing the 100% Disk. It doesn't appear that a single process is reading or writing to my hard drive considerably, but very small activity .1-1MB/s has a serious impact on the disk usage.
Things I have done to attempt to repair this problem:
(1) Turned off the superfetch service
(2) Turned off Windows Search service
(3) Adjusted the pagefile to a constant 2GB
(4) Performed Disk Fragmentation
(5) Performed several disk checks (chdisk)... checked the S.M.A.R.T values
(6) Plenty of performance optimizations, too much to enumerate here.
(7) Ensured all of my Toshiba Satellite drivers are installed and up to date (chipset, bios, etc etc)
Some information about my computer:
Toshiba Satellite S55-C5363
Windows 10 64-bit home premium
Intel Core i7 6700HQ
nVidia GEFORCE GTX 950M
