Abstract: A storage system performing an overwrite, a host system controlling the storage system, and an operating method of the storage system, wherein the storage system includes a memory device; and a controller that receives new data and an overwrite request from the host system, wherein the overwrite request includes a first logical address for old data and a second logical address for the new data, and performs an overwrite operation by writing the new data corresponding to the second logical address to the memory device and invalidating the old data corresponding to the first logical address according to the overwrite request.

Abstract: A computing system includes a storage system configured to store data, and a host configured to compress a data block of a preset size loaded to a memory, generate a merged block of the preset size by merging a compressed block corresponding to the data block, an identifier of a node block referring the data block, and an offset indicating an index of the data block among at least one data block referred by the node block, and provide the merged block to the storage system.

Abstract: A storage device includes a controller configured to: receive, from a host, a plurality of key-value pairs, separate a key from each of the plurality of key-value pairs and a value therefrom, and generate a first key stream by merging a plurality of keys separated from the plurality of key-value pairs, and non-volatile memory configured to store the first key stream. The first key stream is stored, separately from the value separated from each of the plurality of key-value pairs, in the non-volatile memory.
