Hey guys, I'm about to order the components for building my first computer, but I had one question about HHD. What exactly is SATA 3.0gb/s versus just Serial ATA 150. I haven't found much infomation about how to tell if I can use all the extra components of SATA 3.0gb/s. My motherboard choice will be probably be eVGA's Nforce 4 SLI board, which lists SATA II support. Thanks for clearing this up for me.
