Hi there
It's not only the HDD drives themselves but also the controller and how this reacts with the rest of the system - such as Bus speed, I/O caching, data "pre-fetch", etc etc.
You could put the fastest I/O controller in the universe on your system but if the bus I/O throughput on the mobo (chipset etc) can't supply / acquire data from the application quick enough then that's all you are going to get.
5.9 is probably more than adequate for 99% of your apps anyway.
SSD's are another animal completely especially with TRIM support -- you should be able to reach > 7 with these.
