A redundant array of inexpensive tape (RAIT) drives wherein a master tape unit controls a plurality of slave tape units by monitoring their servo and buffer status and sending sync commands, all via data appended to user data sent over a peripheral interface bus interconnecting the master tape unit, the slave tape units, and the host computer. The master tape unit allocates user data received from the host computer between the master tape unit and the slave tape units and controls the slave tape units so that the same length of tape media is processed by the master tape unit and each slave tape unit within the same predetermined period of time.
