A storage space allocation method and storage device relates to the storage area, which is used to allocate storage space according to the size of data stored in each storage device. The method includes: receiving data storage device write request, the data write request includes writing data to be N (S101); according to the particle size distribution and the size of the data to be written to the storage space for the preset, from the N in different allocation granularity for the data write requests to select a distribution the storage space allocation granularity (S102); and to the choice of the allocation granularity for the data write request allocation of storage space (S103), the distribution of particle size distribution as a unit of the storage space, and each has a storage space allocation granularity distribution.
