Intel’s Rapid Storage Technology drivers haven’t been getting a lot of love from me recently, and unfortunately, that isn’t about to change today. A recent Windows 10 upgrade (the Anniversary Update, build 1607) also includes a new Intel RST driver, and on some systems, it’s a source of significant headaches. These systems are stricken by suddenly noisier than usual operation and higher temperatures, both of which stem from higher-than-normal CPU consumption from the Intel RST system service.
How do you know if your system is affected? In Task Manager, you should see IAStorDataSvc consuming CPU cycles in excess of 20%, and sometimes as much as 40%. You can kill the process, but the permanent fix is to uninstall Intel Rapid Storage Technology entirely. The program is unnecessary for the drivers to continue functioning normally, so it won’t hurt to simply leave it out in most cases. Before you do so, however, for safety’s sake, you’ll want to create a System Restore point.
You can also upgrade the package to its latest available version in hopes that this will correct it. If you wish to do so, Intel lists it in the Download section on their site, or you can obtain them directly from your PC manufacturer.
