I threw a Patriot pyro onto my raid with the hope that ISC will "Accelerate" the system. Unfortunately my experiences lead me to believe that Intel storage management only accelerates those with spinner hard drives and not SSD's. So I tossed my 60 gig onto it's own as a system cache only.
It's already plenty fast enough.
If you navigate the Intel software "Help" tab you will see a wealth of easily understood information on just about everything you could want to do. But keep in mind "Accelerating a already fast SSD built system is not available. I have spent a week myself trying.
My storage at the moment is mechanical only. Boot drive is 2xWD Blue 500GB SATA3 on the Intel SATA3 ports in RAID0 and I am thinking of adding the 60GB SSD to it by connecting the drive to the AsMedia SATA3 port available on the board.
Intel Smart Response Technology will work with exisiting RAID arrays on the Intel Storage Controller.
To make this all work I had to move my DVD/RW off the Intel SATA2 to the ASMedia controller and one of my SATA3 HDDs from my RAID0 Boot partition from the SATA3 Port to the now available SATA2 port and then connected the OCZ Vertex 3 60GB to the now available SATA3 Port. (FWIW 7200rpm drives in a RAID0 still come nowhere near 3Gbs so I haven't lost any performance from my RAID0)
Intel Storage Controller lost my RAID0 for half a second and I panicked but it righted itself. So if anyone was wondering, yes you can run a RAID0 on one SATA3 and one SATA2 port on the Z68 chipset.
From there I made sure all SW, Drivers, Firmwares (IRST, BIOS&SSD) were current and then establishing the Smart Response cache was as simple as the Intel "how to guide"
