It clearly states that the sata3 brown ports are available for Raid.
The problem is that those are the Intel 6Gb/s controllers. That's where you want to install your SSD as they provide the highest throughput of any of the onboard SATA options.
If the OP is dead set on running RAID0 HDDs on SATAIII then he'll need to look for a board that has secondary SATAIII RAID controllers like the:Asrock Extreme7 $259.99
It has not only the Intel controllers, but also 2x Marvel 9182 controllers which would work for his HDDs.
It also has 3x 9172 controllers that would work.
