In a lot of cases with people having trouble when running multiple hard drives in a machine - especially with simultaneous access situations, like a RAID check/rebuild - the problem has been a power issue. It seems that some hard drives can cause power draw spikes that some PSUs can't handle, especially if multiple drives are connected to the some cable from the power supply.
I have a 550W common rail PSU and after moving the drive away from the SATA 6 port to a SiL controller port I haven't seen any more problems.
I saw the same timeouts when I first did some lab with the same motherboard, then I only had 1-2 drives in the machine. I doubt my perticular problem is power related.
It's a consistent problem, either it's a hw issue with my motherboard or it's a driver issue.
