MAPPING SYSTEM SELECTION FOR DATA STORAGE DEVICE

摘要

A plurality of mapping systems are maintained for mapping logical addresses for data stored in a Data Storage Device (DSD) to physical addresses for locations in at least one memory of the DSD that store the data. Data is received from a host for storage in the at least one memory, and the received data is stored in a location in the at least one memory. A mapping system is selected from the plurality of mapping systems for mapping the received data based on information provided by the host for the received data or based on information determined by the controller for the received data.
