Abstract: A storage device includes a non-volatile memory including a plurality of memory blocks. The storage device performs an alignment operation in response to receipt of an align command. The alignment operation converts a received logical address of a logical segment into a physical address and allocates the physical address to a physical block address corresponding to a free block. The storage device is further configured to performs a garbage collection in units of the physical block address that indicates one memory block.

Abstract: A method of operating a storage device to perform a garbage collection operation on a nonvolatile memory device having a plurality of memory blocks, the storage device configured to operate based on a multi-stream scheme such that a plurality of data is written into the plurality of memory blocks based on which of a plurality of streams is associated with the plurality of data. The method may include selecting at least two memory blocks among the plurality of memory blocks as victim memory blocks such that the victim memory blocks are configured to store data associated with a same stream of the plurality of streams; and performing the garbage collection operation on the victim memory blocks.
