Abstract

Data management for a storage device which includes a disk for storing data and a non-volatile memory (NVM) for storing a translation table. The data on the disk is associated with a plurality of logical block addresses (LBAs) and the translation table stored in the NVM maps each of the plurality of LBAs to a respective physical block address (PBA) identifying a physical location on the disk storing the data associated with the LBA. Data associated with at least one LBA is written on the disk and the at least one LBA is added to the translation table with a PBA identifying a physical location on the disk storing the written data.
