I used the intel toolbox to do a cleaning and my write speeds shot up a bit. I still have a feeling that the motherboard is doing something to hold me back because the numbers I got above were with a 3.5ghz overclock. Stock speed I get reads of less that 200 in the seq test.
Intel Rapid Storage Technology. Technically it should only be needed if you're running RAID mode (but with the SSD not a part of the raid). So, for those of use who run RAID 0 HDDs and an SSD for booting, RST is a must.
I've always used the default AHCI driver for my SSds and Bench marks have been close to Specs and reviews. However my latest SSD (Gskill Pheonix pro was low on Sequencial and 512 K reads (Right on for 4 K random). It appears the Intel AHCI driver (Included in the Intel Matrix storage driver (Ver 9) is need for optimum performance.

Also, the AHCI driver should be the latest Intel Matrix Storage Technology driver or Rapid Storage Technology for optimum performance.
