Intel® Smart Response Technology enables users to access their most frequently accessed applications and files faster than a system with a hard disk drive alone. Intel Smart Response Technology is an ingredient of the Intel® Rapid Storage Technology and it enables a system to combine the performance of a small solid state drive (SSD) and capacity of a hard disk drive (HDD) to deliver a single high performance and large capacity storage solution.
Intel Smart Response Technology utilizes the SSD as a cache memory between the hard disk drive and system memory. This provides the advantage of having a hard disk drive (or a RAID volume) for maximum storage capacity while delivering an SSD-like overall system performance experience.
In order to be able to activate the acceleration option for the Intel® Rapid Storage Technology the SSHD needs to be in RAID mode at the BIOS level and the SSD portion of the SSHD needs to be set to "Unallocated" Partition at the Windows level.
