This will allow you to access all of your favorite applications much faster. In other words, it will help improve the overall user experience when using your computer. In addition, the Dynamic Storage Accelerator (DSA) feature of Intel Rapid Storage technology is used to adjust the system’s power consumption policy, which can increase SSD performance by 15%.

What causes high CPU utilization for IAStorDataSvc?

If you use an Intel processor, the Intel Storage Data service was probably installed on your computer during the Windows 10 version 21H2 update. It is used to increase the speed of file access and thus improve the performance and usability of your computer. However, if you are not using an SSD on your PC, there is no need to keep it.

Now the main question is why the IAStorDataSvc process uses significant CPU resources or system resources? This is because this technology stores frequently used programs in its cache. When it overflows its cache files or corrupts them, virus or malware infected systems, corrupted system files, etc. are the main cause of 100% IAStorDataSvc CPU usage. and usually reinstalling or removing the Intel Rapid Storage Technology drivers solves this problem.
