    Array types are defined by their RAID level, a number from 0 through 5 (a higher RAID level does not necessarily indicate a higher level of performance or fault tolerance). Rorke Data RAID controllers let you create the types of arrays that have proven to be the most useful for RAID applications: RAID 0, 1, 10 (also known as mirrored), 3, 4, 5, 50, and volume sets.
