Someone check my math, but 100gb in 2 hours, 50gb/hour, 853mb/hour, or
14mb/sec. I wonder if the LTO4 is able to slow down to match that
rate, while that knocks the LTO5 out of streaming?

What sort of network connection does this server have? If it's
1gb/sec, it should support faster than 14mb/sec; maybe increase your
multiplexing?
