Just for reference, here is a graph of IO operations, showing the additional load. The green line is /dev/md0 but that is a RAID mirror of /dev/sda and /dev/sdb so they are taking the load. NOTE: the load on /dev/sdc is constant and would typically be the drive taking the most load. This graph seems very plausible to me.
