Zusammenfassung:According to an example embodiment, a storage device includes: a plurality of non-volatile memories, each non-volatile memory including a plurality of memory blocks; and a controller configured to control the plurality of non-volatile memories, in which the controller is configured to buffer a data block received with a write command from a host, to determine a size of contiguous data based on a starting logical address and a block size of the data block, and to control the plurality of non-volatile memories. And a determination unit configured to determine a slice number indicating a number of non-volatile memories for allocating and storing data blocks in sub-page units based on a size of the contiguous data, and a controller configured to provide the data blocks in sub-page units to one or more non-volatile memories selected from the plurality of non-volatile memories based on the determined number of stripes, and the one or more selected non-volatile memories configured to perform a program operation on t
