Hi RealTelstar. Thanks for the reply and info. Appreciate it. But it wasn't quite what i was asking. My bad, perhaps I was too long winded.
I was interested in knowing why apparently in that particular bit-tech review, benchmarking sata performance. There was a disparity between the intel sata3 controller on the asrock board and the intel sata3 controller on the asus board. --->Bench mark link here<--- According to that benchmark a vertex 3 plugged into the intel sata 3 controller on the asus performed much higher than the same vertex 3 plugged into the intel sata 3 controller on the asrock extreme4 gen3 board (and the rest of the compeditors by the looks of it.) This (like you've explained) shouldn't happen, and was exactly what i was thinking.

However thanks to davefran and his quickbench of his Agility SSD and useful screenshot, I think I can draw think out some theories as to why...
a) the boards were benched at different times, and something in ssd changed (perhaps firmware). eg. old firmware when benching asrock, new firmware when benching the asus.
b) the test for some reason or another were skewed to highlight the asus board (unlikely though and in no way am i saying this is what happend. it's just a possibility)
c) human error when benching... (wrong setting, wrong ports, wrong cables etc.)

What ever the reason, davefran's benchmark screenshot has put me at ease more or less.... He's shown his Asrock Extreme4 Gen3 sata3 ports perform as expected. Thanks all.

If anyone has any other theories and speculation it would be interesting to hear.
