Where did you get the Rapid Storage Technology software from? You're best bet is to download it directly from Intel. I have the same Motherboard as you and have a very similar configuration. I am Raid0 of 2x500GB 7200RPM drives. I installed the system with my SSD unplugged from the Motherboard and installed Windows 7 normally. Once I got the system up and running, I installed all of the motherboard drivers. Once confirming that the system is fully installed (no unknown devices in the Device Manager) I shut down the computer and plugged in the SSD. After it rebooted, I launched RST and clicked on the Accelerate tab. I clicked on a button that would enable the acceleration and selected my Raid0 Array. It then asked me to select the SSD and how much of the space to use. I have a 128GB SSD which will allow me to use up to 64GB. I am able to partition the rest of the space as a separate drive/partition.
Edit
With a new solid state drive and srt, make sure that you also have a partition created on the SSD prior to enabling the SRT
The solution in this case (or at least, a solution) was to use only the drivers that came on the motherboard DVD.
I was attempting to use the latest Intel drivers for the chipset and RST, but the drivers that came on the DVD worked like a charm the first time.

My solution was to do the following, since I didn't care about the having the drive or its data anymore:
I was then able to access the disk normally.
Not sure that it's the best way, but it worked for me.
