What is IAStorDataMgrSvc.exe?

The genuine IAStorDataMgrSvc.exe file is a software component of Intel® Rapid Storage Technology (RST) by Intel Corporation.
This Windows service is the primary executable module of the Intel® Rapid Storage Technology (RST) Service, providing the interface between the Windows OS and the firmware drivers and specific chipsets that implement Intel® Matrix RAID (Redundant Array of Inexpensive Disks) technology. Until 2009, the Intel® Matrix Storage Manager was classified as a software application. After version 9.5 it was renamed as "RST" and considered a driver. Intel is constantly releasing new versions of RST which include new RAID-related features, but new features may require specific hardware to support them. Intel Corporation, in Santa Clara, CA, USA, was founded in 1968 by two Fairchild engineers and is now the world's largest and highest-valued semiconductor manufacturer.

IAStorDataMgrSvc stands for Intel® Array Storage Technology Data Manager Service

Apart of intel's rapid store software
It seems to be wasting about 25% of my dual-core computer's CPU time, in regular pulses, even after a reboot when I would say the computer should be doing just about nothing. It seems to be interfering with smooth mouse movement by hogging CPU in pulses. I had recently updated it when there was a crash message about it, but I have no idea what it's supposed to be doing and am extremely doubtful that I would want it even if it were not causing a very annoying effect, which it is.

Used 25% of my quad core I7! Stopped the process while runnning PC normally, after awhile the PC (Lenovo X220T) gets significantly cooler. Disabled it on startup (in computer management)

It is using 25% of CPU while running PerfectDisk
CPU hog, killed the process and can finally work on the machine again. Not sure what it is, doubt it's dangerous (came pre-installed) but can't tell if it's doing anything useful.
Getting errors using the latest RST file saying my platform isn't supported

Made by intel, came with pc. Not at all dangerous, but definitely annoying, considering it hogs memory and serves no apparent purpose.
its using a significant amount of CPU (20%), but not sure of it has any effect on the performance of the CPU or not, gaming is better with it OFF though

It makes my laptop run very hot. It never seems to stop. This happened immediately after win 10 install. There seems to be no solution other than stopping the app
definite a resource hog and is trying to use storage I do not have. am running sfc and will see what I learn
Hogs around 25% of dual-core i3 CPU time even during system idle. Doesn't appear dangerous, but very annoying, so finally decided to disable at startup and things still work just fine, so appears non-essential.
Hogs memory and causes mouse to be erratic on two different computers. Renamed the file on one computer and fixed the problem. Have not noticed anything that it may have affected.
Per Intel, this is the Intel(R) Rapid Storage Technology and RAID driver. "Provides storage event notification and manages communication between the storage driver and user space applications." Does all this: - Intel® Smart Response Technology - PCIe* storage support - Dynamic storage accelerator - Serial ATA RAID 0, 1, 5, and 10 support - Power-up in standby (PUIS) support NOTE per above that RAID is just One of the things it does -- this is important to avoid confusion for folks: -- IE: "i don't have RAID, so i can disable this, right?" No - that is Not right. :) This driver is performing fine on my system -- very little CPU usage, but in interest of startup optimization, i researched it. Usual start up command line + registry location: C:\Program Files (x86)\Intel\Intel(R) Rapid Storage Technology\IAStorDataMgrSvc.exe HKLM\System\CurrentControlSet\Services\IAStorDataMgrSvc For a quick workaround(not a fix) or test -- you can set adjust the way this service starts or disable it in Services: Start Menu / Programs / Administrative Tools / Services - set to Manual or Disabled and restart your machine, and see: - if everything is still working fine/better - if your problem is solved A Real Fix is something along these lines: - Obtain an updated driver from the Intel site (or even better, your PC manufacturer's website). -- This is usually a good idea -- and *Especially* if your IAStorDataMgrSvc.exe has been corrupted/hijacked. - Possibly adjust BIOS SATA/SATE settings - this might be the actual source of trouble in the first place - OR maybe your BIOS could use a flash update - More troubleshooting options are possible, but just these above will likely fix for +95% of you.

This service used to be useful for operating multi-disk installations (RAIDx) under Windows prior to Windows 10. It helped or helps managing the health status, displays warnings if one disk of a RAID behaves suspiciously and lets you configure your disks. This functionality now seems to be embedded in Win10 anyway so that that this service is not needed anymore.
    (further information)
Installed with Nvidia drivers (i think) it is safe, and it does not affect the performance.

Best practices for resolving IAStorDataMgrSvc issues

A clean and tidy computer is the key requirement for avoiding problems with IAStorDataMgrSvc. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the IAStorDataMgrSvc.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
