In April 2014 I have done a lot of benchmark tests with 2 different systems both running in AHCI and RAID0 mode, doing a comparison of the most interesting Driver/OROM combinations.
You can find the test results and my conclusions within the start post and post #79 of >this< thread.
Additionally I have tried to answer the initial question for the "best" Intel RST/RST(e) driver within the start post of >this< thread.
