Just to be clear - I dont actually have any SSD drives yet. I am intending to get a 60GB SSD and use it on the ASMedia SATA3 Port to then setup Smart Response
I will solve this myself!
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"

Also for a real world experience - Photoshop x64 CS5 used to take about 30sec to get ready for use and now takes about 2 sec. Office applications load like I have Alt+Tab'ed to them.
For $139 AUD I have made a huge difference to the speed of my PC and I am happy I have made the jump - whats more I am hungry for when the price on SSD gets down to ~$0.80-$1/GB
