Unfortunately for a number of apps, Windows 10 tends to have a problem with excessive CPU usage (often caused by a memory leak).

In the case of IAStorDataSvc (Intel Rapid Storage Technology Service), the problem lies in the way the application runs continuously in the “background” of Windows.

The telltale sign of a problem is when you load “Task Manager” and see that the IAStorDataSvc (32-bit) service is constantly running at ~30% or more of CPU capacity.

Cause

The cause of the problem appears to be a problem with the way that Intel (its publisher) has designed IAStorDataSvc.

With problems like this, the typical problem is that the system is executing some kind of recursive function, which inherently consumes a significant (and sometimes increasing) amount of resources.

For many instances of the problem (for different applications), the telltale sign is high memory usage. However, high CPU processing usage is often present as well.

The point is that if none The application in Windows 10 is consuming more system resources than it should, it has a number of adverse effects on the system.

Apart from the obvious degradation in overall system performance, other issues such as overheating and running out of space will often wreck systems with such issues.

For this, the most important thing is to try to solve the problem.

Unfortunately, the Intel Rapid Storage Technology service system is generally guilty in this case; which means that it is better to get rid of it completely.

Solution

The main solution, in this case, is to get rid of the “Intel Rapid Storage Technology” third-party application.

This should leave the driver on your system; just remove the 3rd party app that you use as “control panel” (and is taking up all CPU resources):

1. Uninstall the application “Intel Rapid Storage Technology”

The first step is to completely remove this from your system.

This is a very simple process:

  • In Windows 7, click “Start” > “Control Panel” > “Programs and Features”

  • In Windows 10, right-click the “Start” button > select “Apps & Features”

From the list that appears (in both cases), you need to scroll down to the “Intel Rapid Storage Technology” list, select it, and then click “Uninstall.”

This will open the app uninstall system, which you need to follow and then reboot your PC after it completes.

2. Update Intel SATA Raid Chipset Drivers

Chipset drivers are designed to provide basic level functionality to the various components within a system.

It *may* be the case that you are experiencing an issue with the core chipset driver on your system, leading to issues with CPU usage.

In other words, the “problem” you may have symptomatic of a deeper problem – that problem is usually associated with the SATA Raid controller:

  • Go to Google and search for “Intel Rapid Storage Technology chipset driver”

  • Click on the first Intel link you find

  • It should display a list of drivers; make sure you get the first one that is compatible with your operating system

  • Save the driver to your system

  • Open the download and run the installer.

  • After the installation is complete, reboot your system

If the issue persists, go back to Step 1 to remove the app from your system again.

3. Disable service

Lastly, you should be able to disable the service (if it still shows up).

Windows uses services as a “constant reference point for applications.”

Although they are not applications, they behave in a similar way: they run continuously in the “background” of Windows.

drivers often install “services” on Windows systems and have them run continuously regardless of what else is installed on your system.

You need to ensure that the service for this controller, in particular, is removed:

  • Press the “Windows” + “R” keys on your keyboard

  • Type “services.msc” + press “OK”

  • Scroll down to “Intel Rapid Storage Technology” (considering it’s still there)

  • If it’s still present (it shouldn’t), right click and select “Stop”

  • After this, right click again and select “Properties”

  • In the window that appears, select “Disable” under “Startup type”

  • Click OK to exit the window

This should remove the service from your system, preventing it from consuming any further resources.

After doing this, there are other things to do to try to solve the problem (for good)…

  • Temporarily disable antivirus – Your antivirus application may be blocking system access to core Windows elements that it requires to run (causing some kind of recursive loop as mentioned above). A good test for this is to temporarily disable your antivirus application and see if the problems persist.

  • Update Windows – It can often happen that Windows is having difficulty running the application or has some underlying issue causing it to conflict with the Intel application. You get this a lot with games; they may have some problem with the core graphics driver or something. To fix it, making sure Windows is fully up to date will ensure that it can function effectively.

  • Look for specific support: Your system may have some conflicting application installed, causing the Intel service to consume an increasing amount of resources. The best way to ensure this isn’t a problem is to seek support from someone with specific expertise on your own system. This can be done online (through services like SuperUser) as well as locally.
