LTO-9 is probably not the best route for "Sneakernet" transfers. When Tanenbaum uttered that famous quote, tape was still relatively fast (at least sequentially), as well as it having unparalleled capacity. Nowadays, if you were to do large-but-fast data transfers, i'd chuck all the data on a large SAN and put that in the back of the van. Amazon AWS offer a similar product when moving data from one place to another. Of course, if you had enough LTO-9 drives to load/unload data all in parallel, the transfer time would probably be in the same ballpark as the SAN. But keeping the data synced would be a nightmare, and all those LTO-9 drives would be horrendously expensive. Yes, a van full of data hurtling down the highway will still have much more bandwidth than an internet connection, but nowadays what's in the back of the van is unlikely to be tape.

I need to move 1 PB ..... how long will it take filling and packing enough IBM LTO-9 tapes to send 1 PB ? How long does it takes to fill 1 tape with 18 TB ?
