A bridge device includes: a first interface configured to receive a first set of commands from an application running on a host computer; one or more command processors, each of the one or more command processors being configured to translate the first set of commands and generate a second set of commands based on the first set of commands; a second interface configured to provide the second set of commands to a data storage device; and a computing processor configured to issue an internal command to fetch data from the data storage device and write data to the data storage device in a background mode in an agnostic manner to the host computer while running the application.
