IAStorDataSvc included in Win 10 upgrade uses 20% of CPU

This program appears to have been included with the Win 10 upgrade. It is using 20% of my CPU for long periods of time. What is it and what should I do about it.

Think it's making a library of file locations for fast access.

Once the entire computer has been catalogued it will only ever do minor usage for updating the catalogue, At least that's what I remember a similar program doing on older OS's.

Someone may correct me which would be great.

Isn't that the process for Intel's Rapid Storage Technology?

It shouldn't be taking that much resources.

Its been running for over 10 hours. This has only happened since I upgraded from Win 7 to Win 10. If I use Task Manager to kill the process nothing bad seems to happen. It starts up again if I reboot.

When you open your Task Manager, you can expand the process "IAStorDataSvc" and then you can see that it belongs to Rapid Storage Technology from Intel. So SlackerITGuy is right. I would uninstall and install the driver again.Mine is using 0% CPU and about 17.8MB RAM.

Yes I have seen all that. It is an installed program
C:\Program Files (x86)\Intel\Intel(R) Rapid Storage Technology/IAStorDataMgrSvc.exe

It was clearly placed there by the Win 10 upgrade as shown by the date on some of the files. It doesn't show up in Device Management as a driver. I believe the "drivers" are part of the BIOS which has not been modified. If I uninstall the program there doesn't appear to be any way to reinstall it and it complains about maybe not being able to boot if you uninstall.

It's a third-party application that can be downloaded on your manufacturer's website. It's not necessary though. Uninstalling should not have any effect on booting.

I would disable it via services.msc, or at least leave it at Manual and make its process not boot up with Windows.

RST is good for certain things, like for when Windows for some reason sees your internal drives as external ones right after installation (RST fixes that), but try disabling it, it shouldn't cause any problems.
