> Never underestimate the bandwidth of a station wagon full of backup tapes!

The exact quote [0] by Andrew Tanenbaum is: "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.".

Obligatory xkcd [1].

I met Andy Tanenbaum in 2008 at Vrije Universiteit in Amsterdam. I was the Technology Evangelist for AWS in Europe, giving a seminar there on cloud computing.

I loved him. Funny, smart. I didn't even know he was American until I met him in person (having studied computer science, you're not exactly sure of someone's nationality solely based on his last name).

Nothing wrong with that. Some my best friends are American


Some 2010 vintage calculations, when 16GB microSD cards were considered "big", estimates 275PB would fit in a 1985 Volvo 240:

A 2020 update for that would probably use 256 or 512GB cards resulting in around 4.4 or 8.8EB (And probably twice that again if the cargo capacity of a typical 2020 SUV equivalent of a 1985 Volvo is assumed...)


Pedantically, the overall bandwidth in that scenario is exactly the same as the recording bandwidth of one backup tape. Since bandwidth doesn't scale.

The data transfer rate, however, scales linearly with cardinality...
