IAStorDataSvc uses too much CPU in Windows 10

Unfortunately for various 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 tell-tale sign of a problem is when you load the “Task Manager” and see that the IAStorDataSvc (32-bit) service is constantly running at ~ 30% + CPU capacity.


The cause of the problem appears to be a problem with the way Intel (its publisher) 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 cases of the problem (for different applications), the tell-tale sign is high memory usage. However, there is usually a lot of CPU processing usage as well.

The point is yes some The application in Windows 10 is consuming more system resources than it should, it has a number of adverse effects on the system.

Aside from the obvious degradation in overall system performance, other issues such as overheating and lack of space will often ruin systems with such issues.

To do 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.


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

This should leave the driver in your system; just remove the third-party app you use as a “control panel” (and it’s taking up all your CPU resources):

1. Uninstall the “Intel Rapid Storage Technology” application

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 and Features”

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

This will open the application uninstall system, which you need to follow and then restart your PC once it is complete.

2.Update Intel SATA Raid Chipset Drivers

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

* It * may * be the case that you are experiencing a problem with the core chipset controller in your system, leading to CPU usage issues.

In other words, the “problem” you have may be symptomatic from 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 show 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 problem persists, go back to Step 1 to remove the app from your system again.

3. Disable the service

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

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

While they are not applications, they behave similarly: they run continuously in the “background” of Windows.

Drivers often install “services” on Windows systems and make them run continuously from whatever is installed on your system.

You need to ensure that this particular driver’s service is removed:

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

  • Type “services.msc” + press “OK”

  • Scroll down to “Intel Rapid Storage Technology” (assuming 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 taking up more resources.

After doing this, there are a number of other things to do to try to solve the problem (forever) …

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

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

  • Look for specific support: it may be the case that your system has a conflicting application installed, causing the Intel service to consume increasing amounts of resources. The best way to ensure this is not a problem is to seek the support of someone with specific expertise in your system. This can be done online (through services like SuperUser) or locally.
