Intel Z68 Smart Response an VelociRaptor drive

Does anyone have any experience configuring a  VelociRaptor drive with a SSD for a cache using the Intel Z68 Smart Response feature of my motherboard? I am just curious if this is a waste of money with the speed of  VelociRaptor drive .

Thanks,

Jeff

Mate the velociraptor is the most reliable drive from WD. So not, you did not waste your money
