I'm thinking why can't there be an hardware adapter which we would plug the motherboard SATA cable into, the other side would plug into 2 or more Hard drives. This would look to the main computer & O/S like a single fast drive.
That is what onboard RAID essentially is, apart from the messy cabling.
Hmm. The onboard RAID controllers I've examined (VIA and nForce) were just software implementations with a little BIOS code. Essentially, the controller itself was not RAID-aware, and the Windows driver just talked to individual drives.
Haven't checked out Intel's onboard RAID. I have a benchmark here that claims 0% CPU for a 240MB/s RAID-5 read, which suggests that later versions at least have hardware offload.
