So I was working away on my computer when all of a sudden everything slowed to a crawl and when I checked my system resource monitor this file was using 100 percent of my cpu. After I rebooted I discovered that it was still using 25 percent of my cpu. From internet searches I discovered that this seems to be associated with intels rapid storage technology. What does this do? Will a reinstall of this stop it from being such a resource hog. Can I just get rid of it?
We have the same problem on our brand new Dell. It has been doing this since we first booted up. Dell has been no help with the problem. They had me restore to factory settings, but obviously, since it was this way from day one, that was not going to solve the problem. Is there noone who has a solution?
Disabling the service is a work around to the symptons and not a cure for the problem.
The increased CPU usage is because there is a SATA setting mismatch between the BIOS and the Intel drivers. In my case the BIOS was set to IDE Emulation while the Intel drivers are trying to use AHCI. In previous versions of the Intel drivers this would cause a BSOD at boot and you would never make it to Windows.
So get into your BIOS and check how SATA is operating. Keep in mind if you change an option in the BIOS and it creates a BSOD while booting then go back into the BIOS and try a different option or change it back.
I never found an explanation on the Internet, which is why I joined to inform the community.
Along with keith.wardle, I found my BIOS setting could be changed from ATA to RAID.
At RAID, Windows did not find the disk and didn't start up. Back to ATA ...
uninstall ?? update ??
After trying the BIOS tweak to no avail, I then disabled the "Intel (R) Rapid Storage Technology" service. I thought this safe to do as my single disk is unlikely to be RAID configured ...
Since then my BOINC credits have gone up significantly and FireFox doesn't 'go-slow', ...
You don't have to be a specialist to manage your bios setting thanks to google and places like this. To relief you from performing killing the process every time try to run msconfig, proceed to STARTUP tab and prevent (uncheck) IaStoreIcon or any other similiar or obviously not needed software from booting. Your bios step by step manual to change IDE modes depends on your motherboard manufacturer.
Hi, i am not sure this will ressolve your issue specifically but i also had the same problem and found this forum looking for the answer.After having no problems at all my system began using 29% of its CPU, using the system explorer program i found that the iastordatamgrsvc.exe was using 25 processors and started 1 minute 20 after start up, until that time the CPU was 1%. I remembered using driver scanner which updated 6 older drivers but had not noticed the problem until two days later, i tried a system restore but it only had the last two restore points which were windows updates so i could not change anything back. After reading the post from Hazzardcounty i decided i would uninstall and reload the Intel (R) Rapid Storage Technology driver. i looked through device manager to see which drivers was installed( IDE ATA/ATAPI controllers the express chipset SATA AHCI controller) and noticed it was recently installed. I decided to see if this driver would roll back and it did to driver 10.6.0.1002 which was a 2011 driver, the system restarted and the problem has not happened since.
Hopefully this my help someone else.

The problem for some users is that the latest IRST driver (22.214.171.1243) is a requirement for Windows to pass TRIM commands to SSDs in RAID (only possible on Z77 and Z79 chipsets).
My machine is;
- Asus P8Z77, i5 2500K @ 4.2, Win 7 Pro 64 bit
- 2x Corsair Force 3 90GB in RAID 0 (system), 2x 500GB WD 'Green' (with their PITA 'intellipark' feature set at 5 minutes instead of the default 8 secs via 'WDIDLE') also in RAID 0.
After installing the driver (along with the latest chipset driver), like others I was finding IAStorDataMgrSvc.exe using 25% CPU, and Sandra benchmarks showed read speed on the SSD RAID had immediately decreased from c. 880 MB/s to c. 770 MB/s (straight after installing windows it was close to 1GB/s, but the drive now has 80GB of data on it). Also, access times increased from 0.04 ms to 0.06 - 0.08ms.
I now have IAStorDataMgrSvc.exe set to manual startup, but Windows reports TRIM enabled (via "fsutil behavior query DisableDeleteNotify" at the command prompt - 0 indicates enabled, 1 disabled), although I haven't run any tests to confirm that it is actually *working*.
Frankly, this isn't really satisfactory, and I would hope it can be fixed sooner rather than later.
ETA >> I gather IAStorDataMgrSvc is the configuration console or UI for the SATA driver, but it simply doesn't work. Left on 'automatic (delayed start)' it sits doing nothing but using resources, if I start it manually, Windows tells me that "IAStorUI has stopped working", but after clicking "close the program" the process is still there, behaving exactly as when it starts automatically.
ETA 2 >> After reading this thread on the Intel community forums;
("IAStorUI has stopped working");
it seems that if I had used the F6 option when installing Windows to install '3rd party' mass storage drivers, I would probably not be having this issue.
Unfortunately, re-installing Windows isn't an option for me, as my internet connection is now limited to 3G mobile, and downloading over a year of Windows updates, let alone the half dozen Steam games on my PC would cost a fortune (not to mention the days of work spent tuning and tweaking the system to get it to its current, fast and stable state).
