I've one box here that's using all six onboard ports on an Nvidia MCP55 controller. Two ports are a RAID 1 for the OS and the other 4 have 4 x 500GB drives as a RAID 5. It flies along at the speed I would expect - the array started out as a 3 drive RAID5 and after I'd grown it to 4, I tested it with the filesystem 60% full and got 160MB/s writes and 178MB/s reads.
