http://hardforum.com – Hi. I really need a good pci express raid controller card. My motherboard marvel and intel raid controller sucks. the speed is so low. I want to make it faster. So i decided to get a raid controller card to achieve faster speed. I want to make a raid0 with 2x Samsung 840 pro SSD drive for the main OS system and 2x 2TB Western digital hard drive for backup drive. I looked up LSI raid controller card. I contacted them, and they said they don't support my motherboard. I was wondering if you guys can help me out picking a good raid controller card that supports my motherboard.
