Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the required level of.Although not yet using that terminology, the technologies of the five levels of RAID named in the June 1988 paper were used in various products prior to the paper's publication,Industry manufacturers later redefined the RAID acronym to stand for "Redundant Array of,Many RAID levels employ an error protection scheme called ",Originally, there were five standard levels of RAID, but many variations have evolved, including several,The final array is known as the top array.
