    Abstract: A method of operating a storage device includes receiving, at the storage device, a meta information transfer command based on a data read request. The meta information transfer command is received from a host device. The method further includes receiving, at the storage device, a data read command corresponding to the data read request and the meta information transfer command. The data read command is received from the host device. The method further includes receiving, at the storage device, a plurality of meta data corresponding to the data read request and the meta information transfer command. The plurality of meta data is received from the host device. The method further includes performing a data read operation, at the storage device, based on the data read command and the plurality of meta data.

    Abstract: A storage system includes a host device and a storage device. The host device generates a write command, a logical address of write data corresponding to the write command, and a selective purge tag indicating that the write data are targeted for selective purge. The storage device receives the write command, the logical address, and the selective purge tag, stores write data, and logically erases the stored write data upon receiving an erase command from the host device. In addition, the storage device physically erases the stored write data upon receiving a selective purge request from the host device.

    Abstract: A storage device that includes a nonvolatile memory device is described. The storage device includes areas and a controller. The controller receives a write command and data from an external host device. The controller then preferentially writes the data in an area associated with a turbo write based on a turbo write policy, or in an area not associated with a turbo write based on a normal write policy. The controller also receives a move command from the external host device and moves data stored in the area to a different area based on the move command.

    Abstract: Provided is a storage device which communicates with a host device and configured to set a secure mode of a plurality of commands different in kind. An operating method of the storage device includes receiving a secure request indicating a protection of a first command and a protection of a second command of the plurality of commands, from the host device; setting a secure mode of the first and second commands, based on the secure request; receiving a first request indicating a request to execute the first command, from the host device; outputting a first response indicating failure of the first command to the host device, based on the first request; receiving a second request indicating a request to execute the second command, from the host device; and outputting a second response indicating failure of the second command to the host device, based on the second request.

    Abstract: A storage device includes a nonvolatile memory device including a first region and a second region, and a controller that receives a first operation command including move attribute information and a first logical block address from an external host device and moves first data corresponding from the first region to the second region in response to the received first operation command, and when the first operation command does not include the move attribute information, the controller performs a first operation corresponding to the first operation command.
