A method, apparatus, and a storage system are disclosed for implementing enhanced indirection update for indirected storage devices (solid state drive, a shingled perpendicular magnetic recording Shingled Disk Drive or an indirection perpendicular magnetic recording disk drive). A remapping command generated by a host (102) is used to store indirection data. The remapping command enables remapping of a set of Logical Block Addresses (LBAs) to a different set of LBAs. The remapping command includes a source LBA, length and a destination LBA. The method may alow for indirection reduction without device performance penalty. The source LBA, length and destination is preferably stored on the indirected device. |
