Abstract: An operating method of a storage device that includes a nonvolatile memory device and a controller configured to control the nonvolatile memory device, the method including: detecting, by the controller, a fault of the nonvolatile memory device or the controller, notifying, by the controller, a host device of the fault, notifying, by the controller, the host device of one or more recovery schemes for recovering the fault, and recovering, by the controller, the fault in response to a recovery scheme selected by the host device.

Abstract: A storage device including: a nonvolatile memory device including a plurality of nonvolatile memory cells, a partial storage area and an overprovision storage area; and a controller configured to control the nonvolatile memory device, wherein when the controller detects a fault of the nonvolatile memory device, the controller negates the partial storage area, reassigns the overprovision storage area, which corresponds to a size of a user area, among the partial storage area, determines a device fail if the overprovision storage area is less than an overprovision threshold after the reassigning of the partial storage area, and determines a recovery success if the overprovision storage area is equal to or greater than the overprovision threshold after the reassigning of the partial storage area.

Abstract: A method of operating a storage device that controls input/output of multi-stream data according to a stream ID may include receiving, from a host, a stream control command controlling at least a first stream ID and a second stream ID, determining, in response to the received stream control command, a third stream ID including control commands for the first and second stream IDs, and transmitting the third stream ID to the host.
