* Phase Change Memory is one avenue for research into future storage tech. It's a form of memory where some reversible process is applied to a material (for example heating) in order to change the phase (the type of solid) of a specific portion of the material between a crystalline state (where the atoms form a coherent structure) and an amorphous state (where the atoms still form a solid but are all jumbled up without a discernible structure). As the crystalline and amorphous phases have different conductivities, the resistance of the treated area can be treated as a binary 1 or 0. In theory such storage devices would retain data without power and last for a very long time, as well as have very fast read times (all you have to do is feed a current through an area of the material and measure its resistance to determine binary 1 or 0). One big drawback with phase change technology is that writing is extremely slow and consumers considerable power as you need to get the material to the correct temperature to effect the state change.

* TheBookOfTheNewSun: visiting a vast and decaying library, Severian is told that it contains a cube of crystal the size of the ball of one's thumb, which contains more books than the entire world. The blind librarian is no longer sure where it is, and it is questionable whether he would have a reader anyway.

* In ''Film/{{Superman}}'' and ''SupermanII'', Superman's Fortress of Solitude at the North Pole has a system that stores information on crystals. In SupermanReturns, it is mentioned that the crystal impressively holds 95% of Krypton's entire knowledge. [[RedHerring The remaining 5% is never mentioned again.]]

* ''{{Hyperdrive}}'' featured this trope being replaced by even more effective crystals (as a DVD to Blu-Ray analogue).

** [[http://www.southampton.ac.uk/news/2016/02/5d-data-storage-update.page The University of Southampton has developed 5D data storage]]; a coin-sized glass disk that can hold ''360 TB'' for 13.8 ''billion'' years and is far more resilient than other data storage methods. Easily the closest this trope has come to TruthInTelevision.

* In ''{{Smallville}}'', it was also a crystal that [[VisualEffectsOfAwesome grows into the Fortress of Solitude]]. The Fortress quickly becomes the resident DeusExMachina, for good or for worse. It has since displayed the ability to (sometimes with added crystals) clone kryptonians, remove or restore kryptonian powers and/or memories, imprison kryptonian-grade beings, open a portal to the Phantom Zone, create an eclipse, and holding information as stated above.
* ''SpaceCases'': The Android Thelma exhibited odd behavior throughout the show due to a memory crystal that Harlan accidentally damaged in the first episode. The main ship in the series, the ''Crysta'', also used similar technology.

* In ''TabletopGame/RocketAge'' the Erisians appear to have used crystals as computers. In the modern era their Venusian descendants are able to store psychic energy in shards and make other powerful artefacts, such as the speaker's staff and the Venusian wood axe.
