Hello JK Walker111,
If you want to accelerate one of the 2 RAID 1 you have in the system, once you access the Intel® Rapid Storage Technology you will be able to see the option.
The 2 RAIDs will appear on the software, so make sure you select the one you want to accelerate.
There should not be any partition on the SSD, in order to see the “accelerate” option on the software.
Regarding the BIOS updated, we recommend customers to have the latest BIOS version installed, however if your system is working fine, a BIOS update is not necessary.
