| Zusammenfassung: | A data storage device includes a solid state data storage medium, a set of related data blocks and a controller. The set of related data blocks are non-contiguously stored on the data storage medium and have an original write sequence. The controller, responsive to a defragmentation request, maps the physical block addresses of the set of related data blocks to contiguous logical block addresses in the original write sequence while maintaining the non-contiguous physical block addresses of the set of related data blocks on the data storage medium. |
