A storage device includes a nonvolatile memory device including a plurality of nonvolatile memories; a controller configured to allocate write blocks of the nonvolatile memory device to a plurality of streams provided from an outside; and a buffer memory configured to store a result of allocation of the write blocks to the plurality of streams, wherein the controller is further configured to reallocate the write blocks of the nonvolatile memory device to the plurality of streams based on the result of allocation stored in the buffer memory.

Storage device, storage system, and operating method thereof capable of dynamically allocating write blocks to a stream

A memory storage device is capable of improving reliability of a memory system. The memory storage device comprises a memory controller, and a non-volatile memory connected to the memory controller. A method includes receiving, by the memory controller, a command from a host device, the command requesting lost LBA (logical block address) information resulting from a system shutdown of the memory storage device, in response to the command, providing, by the memory controller, the lost LBA information, and receiving, by the memory controller, recovered data corresponding to the lost LBA information, wherein the lost LBA information includes at least one of the number of LBAs lost by system shutdown, an LBA list lost by system shutdown, and deletion of a previous LBA list lost by system shutdown.
