DiskStress is a program designed to stress new hard drives.  Hard drives normally exhibit a bathtub curve for failure rates where there is a high failure rate or brand new hard drives, then they become reliable, then they become unreliable again later on.  We use this program to add a large workload to new hard drives to weed out any new hard drives which will fail early on.
