Outline five levels of RAID the give different reliabilities, costs, and performances. Block-interleaved with a single check disk (level 4) or with check blocks interspersed (level 5) seem to give best performance for supercomputer I/O or database I/O or both. Note: the TR by the same name (UCB/CSD 87/391) is essentially identical.} }
