Abstract: There is provided a method of operating a storage system that includes a host and a storage device. According to the method, device-filled-ratio of a storage space of a plurality of nonvolatile memory devices in the storage device is queried by the host to the storage device, calculated device-filled-ratio is transmitted, by a storage controller that controls the plurality of nonvolatile memory devices, to the host in response to the querying, an unmap command and target logical block addresses are transmitted, by the host, to the storage device based on the calculated device-filled-ratio, and physical block addresses corresponding to the target logical block addresses are deallocated, by the storage device, in response to the unmap command.

Abstract: A processor configured to control a storage device includes at least one host write buffer generated based on device information of the storage device, and a control module configured to control the at least one host write buffer. The control module is further configured to store, in the at least one host write buffer, a plurality of write commands and merge the plurality of write commands to generate a merged write command.

Abstract: An operation method is for a storage device that includes a storing unit storing a plurality of error logs and a physical layer and exchanges an electrical signal with a host via the physical layer. The operation method includes receiving a debugging command from the host, setting a first value at a first attribute included in the physical layer in response to the debugging command, setting a second value different from the first value at the first attribute in response to a control of the host, setting one among the plurality of error logs at a second attribute based on the first attribute at which the second value is set, and transmitting the error log set at the second attribute to the host in response to a control of the host.

Abstract: A computing system includes a storage system configured to store data, and a host configured to compress a data block of a preset size loaded to a memory, generate a merged block of the preset size by merging a compressed block corresponding to the data block, an identifier of a node block referring the data block, and an offset indicating an index of the data block among at least one data block referred by the node block, and provide the merged block to the storage system.
