Even without a RAID array, and with Intel Rapid Storage turned OFF on the ASUS Z97 motherboard, whenever I logged in as a standard user, I'd get an Intel Rapid Storage popup message telling me I had a storage error, and to open the Intel app for details. But a standard user can't open the app. So I logged on as Administrator and opened the app -- which told me everything was OK. I disabled the service, and THAT problem was solved. It looks nearly impossible to get help from Intel.
