How to fix
High CPU Usage by IAStorDataSvc
on Windows

I’ve just run a Windows 10 upgrade and everything seems working great. However, I wonder if it's normal that IAStorDataSvc process is running all the time and consuming almost 30% CPU. I’ve stopped it via Task Manager, but once I restart my laptop, it starts running on the background all the time. Can anyone help with a solution, please?

IAStorDataSvc service is a part of Intel Rapid Storage software, which is a part of the Windows system. The name of the service is translated as Intel Storage Data Service.  Its function is to ensure proper data transfer on your PC, as well as grant quick access to programs/apps you frequently use. For the proper performance, the service requires SSD card as it seeks to maintain access to Hard Disk Drive by automatically saving apps/programs to SSD.[ref en-3]

That’s because home users can easily do without Intel Rapid Storage Technology.[ref en-2] However, the software should remain in the company PC because it ensures fast access to important data and programs.

The majority of users who experienced IAStorDataSvc high CPU usage problem were using driver version 11.5. In general, no matter what drivers are run on your device, IAStorDataSvc service should not use so much CPU.[ref en-1] The reason why it does so frequently is related to cache. To save new data, it identifies/creates most frequently used programs, apps, upgrades, etc. as its cache.
