There are certain requirements to have the Acceleration tab enabled in Intel® Rapid Storage Technology so I want to confirm with you the following:
- The Chipset mode in the BIOS must be set as RAID.
- The minimum capacity of the SSD must be 18.5.
- The SSD must be connected to the Intel® SATA controllers. If possible on SATA port #1.
- Make sure the SSD does not contain partitions
It is also extremely important to say that the feature will not be enabled/visible if the SSD is the only Drive connected to the system as it is not possible to accelerate SSD drives.
