Yeah.. but that's assuming it's not being run by an old PowerMac 7200 on a
10Mb shared
ethernet connection... and it's DDS-1, not 3!

The AIT/DLT system is expensive, but in theory more reliable, and higher
capacity, and
as you can see from above, quite a bit faster (even though the AIT one
should be ~528GB/day).

The theoretical speed of the tape is nothing compared to the actual speed of
the network and
the drives supplying the data, and if there's someone using the machine, it
slows down even more!
