Adaptive construction method of storage block and storage device

The invention relates to a self-adaptive construction method of a storage block and storage equipment, and relates to the technical field of data storage. Whether the storage device is in the FDP application scene or not is determined through the storage device according to the enabling information of flexible data placement, recovery units with different capacities are constructed in the FDP application scene and the non-FDP application scene respectively for garbage recovery, and the capacity of the recovery unit in the FDP application scene is smaller than that of the recovery unit in the non-FDP application scene. The requirement for reducing the capacity of the recovery unit in an FDP application scene and the requirement for increasing the capacity of the recovery unit in a non-FDP application scene are met, the storage equipment can be compatible with the application scenes of the FDP technology and the non-FDP technology at the same time, the application scenes of the storage equipment are expanded, t
