RAID level-x0

Refers to RAID level-00, level-10, level-1E0, and level-50. These RAID levels use spanned arrays (array of arrays) to enable the use of up to 60 physical drives. RAID level-00 provides no data redundancy, but provides performance acceleration and allows 100% of the physical drive storage capacity to be used. RAID levels -10, -1E, and -50 provide full data protection, performance acceleration, and greater reliability, although only 67-94% of physical drive storage capacity can be used.
