Abstract: A storage system and method for interleaving a plurality of logical sectors in the storage system is disclosed. The method includes: dividing each logical sector into a predetermined number of slices; sequentially indexing the logical sectors, wherein each logical sector is identified by a logical sector index; sequentially indexing the predetermined number of slices in each logical sector, wherein each slice of the predetermined number of slices is identified by a slice index within each logical sector; and interleaving the logical sectors according to a slice interleaving process. The interleaving step further includes: a) identifying a first indexed slice of a first indexed logical sector as an initial slice; and b) identifying a subsequent slice by advancing the slice index to a subsequent index in the slice index sequence and advancing the logical sector index to a subsequent index in the logical sector index sequence.
