Thank you for contacting the Intel community.
In this case, for you to have this option available in the Intel® Rapid Storage Technology you will need to have the BIOS configured as RAID mode, if you don’t have the bios set to RAID mode, then to have this option available you will need to reinstall the operating system with the BIOS set as RAID mode.
If you system is set to RAID mode already, all you need to do is to launch the IRST and then click the acceleration button and follow the steps. You can take a look at the Intel® Smart Response Technology User Guide
Please bear in mind that you will need a SSD 2.5 to accelerate it.
