The Data Cube is a small form-factor lightweight data storage device

S01E09-FredJohnson Broadcasts Donnager DataCube Evidence 00

The Data Cube is used for secure data storage and sharing. The TV show prop used in these scenes resembles a memory card more than a literal "cube" per se. Both the books and the TV show refer to them as "data cubes" regardless of their actual physical form factor. The data cube doesn' t require physical contact to transfer data as it apparently incorporates wireless communication capabilities.

  • Joe Miller finds scattered "data cubes" strewn all over the workshop of "Bizi Betiko", AKA "Sherpa", the data broker that Julie Mao used

Media Edit

  • Where has Joe Miller seen a robot rodent before?

  • In the TV show, Fred Johnson took the data from Lopez unbeknownst to the Canterbury/Donnager survivors but in the book, the data was a bargaining chip in brokering their independence to leave Tycho and investigate freely.
  • In the books, Miller did not use data cube from Julie Mao to uncover the Scopuli connection. He instead looked for patterns in shipping routes and flight plans.
