Hello, I have the Abit KA7-100 motherboard with the HPT370 ATA-100 controller. There is an undocumented RAID feature if you have the right BIOS. I was thinking about trying this out. I was wondering if any of you guys have this and have it working. I have 2 8.4Gb Maxtor hard drives (different model numbers) and they are both ATA33. Will I get a large performance increase with this setup? Also, those of you with it working, could you tell me the best way of setting this up? Thanks everyone.
