poor SATA performance on X79 chipsets compared to P67

[readymix]

I have an Asus Rampage IV Formula with a Sandisk Extreme 240GB and the latest Intel chipset and RSTe drivers and the SSD speed positively stinks. I previously had a Samsung 830 256GB and thought it was the drive that was the problem. These RSTe drivers are TERRIBLE (as of 6/7/12). My boot-up time (not counting time to post) is about 25 seconds (takes six to eight seconds on older systems using this same SSD) and my ATTO scores are way below what they should be. And yes, all the bios and software tweaks have been make to ensure max performance. I tried switching to the ASMEDIA SATA ports and they were even worse. Intel builds this high end X79 chipset only to leave its users with poor SSD performance because we can't use the "normal" non-RSTe drivers. If anyone figures out a solution short of future driver updates, please post!

i've got issues with the rste shit too! none critical. but, guess what? ssd performance is not one of them. crystal disk is in line with samsung's sata6 specs. wth.
