Abstract
A data storage apparatus that includes a storage device and a processor coupled to the storage device. The processor is configured to receive a read request for a first translation table entry associated with a logical block, identify a dump unit associated with the logical block using a hash function, determine a dump group associated with the dump unit, and identify a second translation table entry associated with the dump unit.
