Today, the equivalent is an Amazon Snowmobile, a 45 foot shipping container weighing 34 tons transported on a semi-truck. Transfers about 100 petabytes at a time. They claim it can be filled "in less than 10 days". Of course, multiple Snowmobiles can be used in parallel if you have exabytes to transfer.

Assuming it takes about 3 weeks to turn around, my arithmetic says each truck has a bandwidth of about 460 Gbps.

"Q: How do I connect my data center to Snowmobile?

Each Snowmobile comes with a removable high-speed connector rack on wheels with two kilometers of ruggedized networking cable."
