You are forgetting the time it takes to copy the data to and from these cards. Data may be transported, but it is not usable until you copy it. Copying 20 TiB is probaply going to take some time
Fastest SD card has ~300MB/s read speed and ~250MB/s write speed. Assuming you can write to those cards in parallel, that means you'll need an additional one hour to write the data to the SD cards and another one hour to read them back. So 4 hours in total which halves the data rates to 1.39 GB/s.
That's assuming the card can actually sustain ~250MB/s write speed during the full 1TB copy. It probably can if the card is freshly formatted but I haven't actually tested it myself.
We had a TV report about a photographer who actually transfered big files with via horse because the transfer over the internet was slower than a calm ride.

When Baldur's Gate 3 came out our group of friends wanted to start a game together. Since one of our friends, living about a kilometer away, has shitty internet it was faster for me to download the game myself, copy it to a USB stick, have it driven over by another friend, copy it onto the friends PC and verify file integrity than downloading it.
For render the first picture of a black hole a couple of uear ago, the data transfer was done through hdds transported by a plane, than a data transfer through Internet, because the former was so much faster.
I'm assuming English isn't your first language, but "IPoAC would've it's purpose" is grammatically awkward. "Would've" doesn't really work for possession. Instead you can use "would have," but people would typically say "IPoAC has it's purpose"
Thanks for the clarification. You're right, English isn't my first language.
I'm a bit confused by your sentence:
""Would've" me doesn't really work fur possession. Instead you can use "would have""
That's the same thing, isn't it?
My idea with using "would've" was that IPoAC would have it's purpose, if it was a thing. I'm missing the descriptive word in either language right now.
Ahh, the good old RFCs dated April, 1st. This one is number 1149 ( A Standard for the Transmission of IP Datagrams on Avian Carriers), and got later updated in RFC 2549 (IP over Avian Carriers with Quality of Service).
Reminds be of the conversations about transferring hard drives using the public transport system in my city. Good bandwidth, terrible latency. Then everyone got faster internet and stopped pirating
