I have the gigabyte X58A-UD3R. it has the native intel controller Sata for raid, or Marvell Sata 6G for raid or Jmicron Gsata with raid.. I installed them on the Marvell and my proformace is actually lower then it was on my old AMD 750sb chipset by about 50MB a second? Should i try the intell controler and put my CDrom and other HD on the sata6g?
