Abstract: A host includes: an index tree storing an index including information for identifying a versioning key; and an index update buffer storing a write key included in data subject to a write request and the versioning key corresponding to the write key. When a preset update condition is satisfied, the host transfers the versioning key stored in the index update buffer to the index tree, and when the index update buffer requires recovery, the host designates a recovery section of memory of the storage device including data corresponding to the versioning key which has not been updated to the index tree, to be read by a plurality of threads, reads data included in the recovery section from the storage device through the plurality of threads, and inserts the read data into the index update buffer to recover the index update buffer.

Abstract: A storage device includes a controller and nonvolatile memories. The controller receives write commands having virtual stream identifiers (IDs), receives discard commands having the virtual stream IDs, and determines a lifetime of write data to which each of the virtual stream IDs is assigned. The nonvolatile memories are accessed by the controller depending on physical stream IDs. The controller maps the virtual stream IDs and the physical stream IDs based on the lifetime of the write data.
