摘要： A data storage device is disclosed comprising at least one head configured to access a magnetic tape. A plurality of access commands are stored in a command queue, and a wear value is generated for each access command in the command queue, wherein the wear value represents a level of wear on the head or magnetic tape associated with executing the access command. An execution order for the access commands is generated based on the wear values, and at least one of the access commands is executed based on the execution order.

摘要： Systems and methods are disclosed for managing distributed data storage. A data storage device is configured to operate in at least two modes of operation, including a first mode, in which the data storage device may sync a file directory with a corresponding file directory of a separate data storage device when the data storage devices are connected over a broadcast connection in a first local area network (LAN). In a second mode of operation, the data storage device may connect to a host device over a dedicated point-to-point connection over a second LAN when the data storage device is not connected to the first LAN.
