Abstract: An apparatus includes a host device and a data storage device. The host device is configured to store a first translation map for converting a logical sector to a logical erase unit. The data storage device includes a plurality of flash memory devices and a memory controller operationally coupled with the flash memory devices, each of the flash memory devices being arranged into a plurality of erase units, each of the erase units having a plurality of pages for storing data. The memory controller is configured to receive a second translation map from the host device, the second translation map for converting a logical erase unit to a physical erase unit within the flash memory devices, and store the second translation map in a memory module on the data storage device.
