Part of our showcase extreme gaming desktop testing we installed Windows 7 x64 on the Marvell raid controller, then reinstalled Windows built into our Intel raid controller.
Stick with Intel Raid Controllers
As you can see if you are sticking to the on-board raid configuration to save a dollar, stick with the Intel raid controllers! We can DEFINITELY feel the difference in performance without a single doubt.
This test was done with 2 120GB OCZ MaxIOPS SSD drives in a RAID0 configuration.
