Abstract:
Methods, apparatus and systems for data storage devices that include non-volatile memory (NVM) are described. One such apparatus includes a non-volatile memory, a data storage device controller configured to receive a command from a host device, and wherein the data storage device controller comprises a file system analyzer comprising a determination circuit configured to determine based on the command from the host device whether a logical block address (LBA) referenced in the command is part of a known file extent, and a selection circuit configured to select a flash translation layer (FTL) workflow for the file extent in response to the determination that the LBA referenced in the command is part of the known file extent.
