Excellent way to illustrate the difference between bandwidth and latency.

I like it, you may be on to something. So we basically just need to convince the gamers to become good old fashioned bums that ride around on freight trains all day...

Gamers have to actually get in a RR car and physically fight. Much more realistic and very low latency.

        Well, assuming that the rail was moving at a similar speed to
        the trucks - say 60MPH, And the rail cars were ~60 feet in
        length, and had the same volume as the 53 foot truck.
        60MPH = 316,800 FPH / 60 Feet = 5280 Railcars per hour, 88
        railcars per minute, 1.46666 rail cars per second.
        Once the first one arrived, you'd have a continous feed of
        26857.6Pbit/S
        Get to work on the automatic tape transcription device.  You
        only need to write ~557,136 tapes per second, and don't forget
        loading them on the train...

            No, what would it be if you had continuous railcar
            transport??? We could eliminate all the fiber with railroads!

            Chicago to LA is 30 hours by truck.
            Typical 53 foot trailer is 3816 cubic feet.
            A LTO-7 tape can hold 6TB
            The volume of a LTO-7 tape is just under 0.01 cubic foot
            (0.00839973....) We'll use 0.01 cubic foot.
            A 53 foot trailer packed completely full can hold 381600
            Tapes X 6TB = 2,289,600TB, or 2289 PB.
            2,289,600TB/30hours = 76320TB/hr.
            or
            1272TB/min
            or
            21.2TB/sec.
            or
            169.6Tbit/second.

                I can't remember which but there was a nanog
                presentation a few years ago about max bandwidth and
                the top of the chart was still listed as a 747 cargo
                full of optical media..   Now as far as getting that
                data on and off the media....

                    For the seed you need to understand this quote:

                    "/Never underestimate the bandwidth of a station
                    wagon full of tapes
                    hurtling down the highway/." —Tanenbaum, Andrew S.

                    0-13-166836-6.

                    I'd highly recommend you think about how to move
                    that seed via Fedex or
                    UPS.    You're already going to be storing the
                    data somewhere, if
                    possible, take whatever it is your storing it on
                    (or backing it up on)
                    to the origin location and copy it to it....
                    *then* ship it to and
                    install it in your datacenter. It is likely that
                    the cost of doing
                    this will actually be less than the cost of buying
                    a circuit which will
                    do this in a reasonable amount of time, especially
                    if you are buying a
                    piece of hardware to store this data (likely).

                    For the updates,  4pb per year is just over 1Mb/s
                    if I did the math
                    correctly....   This is in the realm of normal
                    internet, assuming the
                    data grows gradually throughout a year.

                    I'll let others point you toward a 10Gig wave if
                    you'd rather not use
                    the "move media" approach.

                    datacenter? We are in the southeast and they are

                        data amount would be a seed of 5pb and growth
                    of 4pb per year. The
                        networking on our side would be 100gbit LAN.
