Got this new board set up and running.  I want my WD hard drive to be able to access at 6 GB/S like it's advertised, but I'm confused.  I thought RAID was for multiple drives.  I only have one.  So how can I set this up?  I installed the ASPI driver and enabled it in the BIOS.  I have the drive plugged into 
the GSATA ports.  Do I have to reinstall the OS?  This is the bottleneck on my system.  The HD is holding the performance index to 5.9 and everything else is 7.5 or better.
