I'm not the original author:
Trebuchets are the most technologically advanced siege engines of all time, and are capable of hurling a 90kg stone over 300m using a counterweight.
With this in mind, we can perform the following calculations:
A 22TB WD Red Pro drive weighs 670g, with a maximum hurl weight of 90kg, trebuchet can hurl 134 drives at once, totalling 2,948 TB of data.
The average speed of a trebuchet projectile is 54m/s and the average size of an American 'block' is 100m. Lets presume 3 blocks to get our full trebuchets use (fuck you catapults).
It'll take 5.5 seconds for the projectile to go from launch to dramatic landing, meaning a throughput of 536TB a second.
Therefore, trebuchets are the best transfer method.
