I have seen a reply by intel in similar situation as said in
Unable to configure SSD cache on new Lenovo Y500
In this, it is said
"SSD cache or acceleration does not work under AHCI. If you like to enable this feature the computer requires RAID mode. If your computer model does not support RAID then, SSD cache is not supported."
In BIOS, only AHCI or IDE mode is available. Hence the doubt whether SSD cache is used or not?
