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.
