Data crystal chip

Summary

These data crystal chips are used for transferring "hard" data, meaning data that cannot be transferred over Slipspace, or through a transmission because of the data's sensitive nature. Examples of such data include AI data, navigation data, weapon technological charts, ect. It resembles a floppy disk.

Uses

The Data Crystal Chip can be utilized for many things. Here are a few of its uses.

• Carrying the data for an Artificial Intelligence Construct, like Cortana or Deja.
• Carrying star charts, maps, and other navigation data. These chips must be destroyed if contact is ever made with the Covenant, as per the Cole Protocol. This did not happen aboard the Circumference during The Battle of Reach and SPARTAN-117 and SPARTAN-058 were sent to destroy its Data Crystal Chip.
• Carrying sensitive data, such as intelligence. Dr. Catherine Halsey had compiled two of these with all known information on the Flood.
