Both HDtune Pro and HDTach RW showed improvements were to be had using there expansion card. However, the results were not that significant, boosting the speed of the ICH10R controller by a little over 10MB/s in all the tests run evening out at around 9% improvment by using the Asus 6G controller. What IS significant is the burst rate which increases by a fair margin in both read and write tests with improvements that double in HDTach RW and increase by over 50% in HDtune pro. Burst speed gives an indication of the controllers speed and as the above results show, the Asus PCIe GEN2 SATA6G controller performs admirably in this department. In todays market, storage space is still held high on the list and perhaps the biggest reason why SSD's are still not as popular as mechanical hard disks so this leap in burst speed will no doubt be greeted with open arms by those looking for a large storage solution AND speed.
