   @coolboymew the funniest part is that occasionally someone does strap whatever the current equivalent of a terabyte SD card is to a homing pigeon and beats an ISP in throughput. I’ve seen news of one of those cases relatively recently. (This year or the past couple of years.)

     And I've heard that people still transfer some files like backups in similar ways, because while internet is pretty good for latency and small packets, a massive jumbo packet like a truck just beats it entirely.

     @Amikke @coolboymew And it makes a lot of sense, it's not data which needs to be streamed and it's big, so physical transfers are what makes sense.
     
     Specially as a case full of HDDs also means that you're cheating a bit like if you'd have several internet links instead of one.

     @lanodan @coolboymew apparently the Event Horizon Telescope (global array of radio-telescopes) uses people flying on planes with suitcases full of HDDs as the main form of data transfer.

     Each telescope records at a rate of 64 Gbps, and each observation period can last more than 10 hours. This means each site generates around half a petabyte of data per run. With each site recording simultaneously, Blackburn said the high recording speed and sheer volume of data captured made it impractical to upload to a cloud.

     @lanodan @coolboymew there’s a picture of that somewhere but I can’t find it :-/
