Large arrays of disks have been proposed as a way to meet the need for increasing IO bandwidth. This paper examines disk array performance in a random IO environment. It also presents the results of performance testing using the Prime IOBENCH™ benchmark on a combination of disk striping, RAID 1, and RAID 5 disk arrays. It concludes, that for a given number of disk drives, that both RAID 1 and RAID 5 have acceptable performance in a read environment, while RAID 5 degrades significantly in an update intensive environment.
