Data storage architectures employing Redundant Arrays of Independent Disks (RAIDs) were created to improve reliability over the typical non-redundant hard disk drive (HDD) used in most personal computers. As the number of HDDs in a storage system increases, the probability of failure and subsequent data loss increase as well. As background, this presentation briefly introduces the popular RAID architectures and then explores the causes of HDD failures. The effects of the failures are then grouped into two major areas, each of which has a different impact on RAID reliability. As HDD capacities continue to increase beyond the multi-terabyte capacity, the number and frequency of latent media defects will increase disproportionately when compared to the number and frequency of HDD operational failures. RAID system architects must understand these effects when designing mitigating processes, such as RAID scrubbing, and the HDD magnetics designers must try to improve designs to keep the number of, and rate of added media defects low.
