Argh, I did misspeak when I said there was USB 3.0 support. SB850 is 
still 2.0 and I forgot that the mobo makers are using 3rd party USB 3 
controllers. SATA 6.0 really only benefits SATA 6.0 SSD drives. Although 
there are though new hybrid drives coming down the pipe but I am 
skeptical about them. Thanks for the correction.
