But, if your disk is constantly at 100% disk usage, it might be a serious problem. If this 100% disk usage persists for several days, things may take a turn for the worse. This might be the reason of open your application slowly and hang, which will increase your pc temperature and even may damage your disk permanently. 100% disk usage can also lead to mechanical failure of your disk.
How to Understand That 100% Disk Usage is Slowing Down Your PC
High disk usage affects your pc performance. Your pc will take more time than usual to open an application or open a photo or others. It starts with a general slowdown of your pc, and may even damage your disk. To understand this, imagine you are browsing on a website or open a photo stored on your hard disk, and if that process takes five or even ten to fifteen seconds more than usual to open, then you should understand that high disk usage might be the main culprit for that. Sometimes, processes like Microsoft compatibility telemetry or Wsappx error also cause this error. Here are a few examples of when the disk is being used more than usual:
- Opening an application: it will take more time than usual to open an application. Even the might not able to open or suddenly stopped while running or got lagged or hanged.

- Gaming: it will take more time to load a page. Loading the game and enter a new page will take a noticeably longer time. Even the game might hang in the middle of the match. That’s annoying.
- Audible noises: high disk usage might be the reason for increasing the temperature. Mechanical hard disks are quite noisy, and high disk usage will increase the noisiness when busy.

AHCI PCI-E model causes these symptoms in Windows 10 when running with the storahci.sys drive. Because of a firmware bug, the solid-state drive (SSD) can not properly complete input or output when message signaled interrupt (MSI) mode is enabled.
So, there are two different moves to fix 100 disk usage on windows 10 by fixing the storahci.sys drive.

Step 4: Navigate to “KHEY_ LOCAL_MACHINE\System\CurrentControlSet\enum\PCI\< AHCI controller>\device parameter\ interrupt management \ MessageSignaledInterrruptProperties”, where <ahci controller> refers to the device instance path that you find in step 2. Now, change the value of the MSISupported key from 1 to 0.
