Abstract
Systems and method provide for the writing of a data block and corresponding metadata block to a storage location. Metadata and data block are encoded separately. The metadata and data block may be moved to a different location due to garbage collection, defragmentation, or some other prompt. The metadata is decoded, modified, re-encoded and written to the different location whereas the data block can be written to the new location without re-encoding.
