Yes! You have the ability to control more than one LTO tape deck. You cannot write different archives at the same time however. You can create duplicate copies of the same content on two different drives. Remember, a true archive adheres to the 2+2=1 rule: 2 tapes in 2 different locations = 1 true archive.
Note: PreRoll Post Windows can handle separate read and writes simultaneously to different LTO drives, and also queues read/writes to a single drive as needed. myLTO can also copy different content to different LTO drives at the same time.
