A disk drive having a disk, a head actuated over the disk, a volatile semiconductor memory (VSM), a command queue, and control circuitry operable to receive a plurality of write commands from a host, store the plurality of write commands in the command queue, store write data for the plurality of write commands in the VSM, and flush, from the VSM to the disk, a portion of the write data corresponding to a predetermined number of tracks.

Data flush from cache to disk based on track limit

A data storage device is disclosed comprising a non-volatile memory comprising a plurality of sectors. At least one alignment zone is defined in the non-volatile memory comprising a plurality of chunks including a plurality of data chunks and a plurality of pad chunks, wherein each chunk comprises a plurality of sectors. Each sector is operable to store X host blocks, the alignment zone comprises at least X&#x2212;1 pad chunks, and control circuitry is operable to shift the data chunks of the alignment zone by a number of chunks equal to or less than X&#x2212;1 plus a corresponding offset.

Data storage device shifting data chunks of alignment zone relative to sector boundaries

A data storage device is disclosed comprising a non-volatile memory comprising a plurality of sectors. A partition map is evaluated that identifies a partition accessed through a plurality of logical block addresses (LBAs), where each LBA maps to a fraction of a sector. A partition offset is determined for the partition relative to a boundary of one of the sectors. N write commands are received each having a write offset relative to a corresponding sector. When the write offset for X of the N write commands matches the partition offset, at least part of the partition is moved to align at least part of the partition to a boundary of one of the sectors.
