A method of operating a data storage device includes fetching a first plurality of commands from at least one submission queue generated in a host memory, determining whether a ratio of a second plurality of commands from among the fetched first plurality of commands exceeds a reference ratio, and adjusting a number of a plurality of pointers being fetched at substantially a same time based on determining whether the ratio exceeds the reference ratio. The second plurality of commands has a same property, the plurality of pointers indicates a physical address of the host memory corresponding to the first plurality of commands, and the data storage device includes a storage controller configured to perform an interfacing operation with a host including the host memory.

Data storage device and method of processing data thereof

A memory controller comprises a host interface block comprising a compression ratio calculator configured to determine whether a compression ratio of input data exceeds a predetermined compression ratio, and a compression block configured to compress the input data as a consequence of the host compression ratio calculator determining that the compression ratio exceeds the predetermined compression ratio.
