Claim:
1. A method comprising: writing a first data block to a first granule of multiple individual granules in a granule storage area of data storage, the first granule constrained for a series of write operations to receive data of a first range of logical block addresses (LBAs) including an LBA of the first data block; writing a second data block to a second granule of the multiple individual granules, the second granule constrained for the series of write operations to receive data of a second range of LBAs including an LBA of the second data block, wherein the multiple individual granules are recorded in a single shingled magnetic recording band and wherein at least two of the multiple individual granules are simultaneously constrained to store data of overlapping subsets of logical block addresses; sorting together data blocks of the first granule and the second granule to form a compacted granule; and writing the compacted granule to a destination storage area.
