Today, flash drives. Tomorrow, precious gems!
Rather than use magnetic, optical, flash drive or solid-state drive
based information storage mediums, in the future there will be ways to read and write data onto transparent crystaline solids. This jump in technology usually makes each Data Crystal a veritable Bag of Holding
for information, uploading and downloading entire planetary databases in seconds. The crystals may be shaped like quartz, techno Crystal Balls
or as diamond or gem cut jewelry.
Data Crystals often double as video recorders and Hologram
emitters, allowing owners to record, store and project their home movies. Because Power Glows
, these Data Crystal hologram projectors can often even do without an external power source.
Truth in Television
with the fact that deep inside all of the plastic cladding, all solid-state electronic devices are based on crystalline semiconductors; also, in that a three-dimensional storage matrix should in theory offer orders of magnitude greater information density for a given volume than any possible refinement of the essentially two-dimensional storage methods in use today.

Anime and Manga
- The Gosroth's log in Crest of the Stars takes the form of a data crystal, which is passed on to Lafiel and Jinto when they're ordered to flee an impending battle.
- A major MacGuffin in Battle Angel Alita: Last Order is an ancient computer program encoded on a crystal.
- In post Infinite Crisis Superman stories, Superman's Fortress of Solitude uses sunstone crystals to work his computer. This was taken from the Superman films (see below).
- In Empath: The Luckiest Smurf, all memory of Smurf history that was transferred into Empath's mind from his great-grandson in the future has been transferred into a magical memory crystal, which in-universe will be given to Peyo so that he can create The Smurfs.
- Star Wars has holocron crystals.
- One of the characters in the Wild Cards series is Jube the Walrus. As an agent of the interstellar trading consortium known as the Network, he has advance technological devices such as recording crystals that can store information.
- In the "Darwath Trilogy" by Barbara Hambly, the earlier human civilization that built the Keep of Dare used magitech data crystals to store information.
- Sholan Alliance: Sholan computers make extensive use of removable data crystals. When the lead characters are preparing to return from their trip to the past, One of the ancient locals points out the location where they've hidden an important data crystal that is later recovered in the present.
- In Smallville, it was also a crystal that grows into the Fortress of Solitude. The Fortress quickly becomes the resident Deus ex Machina, 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.
- Space Cases: 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.
- One episode of Eureka introduced Data Diamonds. Capable of storing utterly massive amounts of information on the molecular level. They needed proper hardware though as lesser computers combusted from the extreme processing.
- Alphas, one episode featured a necklace made from some strange crystals, and they figure out that it stores information on specially arranged molecule structures.
- In the first season of Fringe, there were the glass disks and they were data storage devices, Massive Dynamic was able to read information from them.
- Farscape, too, had data crystals in several episodes, most notably the navigation crystal in "DNA Mad Scientist."
- Hyperdrive featured this trope being replaced by even more effective crystals (as a DVD to Blu-Ray analogue).
- Tracker had this, they were maps stored on crystals. The first one got left behind at an alien-theme restaurant after a fight, but Cole found the second one hidden in a stored museum piece. They were maps of the Lake Michigan area to show the way to the Doomsday Device hidden under the Watchfire bar.
- Shows up occasionally in Star Trek, primarily in later TNG, DS9, and Voyager.
- In the Stargate 'verse most space-faring species use crystals extensively in their computers. In one case a storage crystal from an old Goa'uld research base is dismissed as a simple decoration by archaeologists, until the invaders hanging overhead start looking for it.
- Data Crystals are a popular intergalactic standard in Babylon 5.
- Shadowrun. Information can stored on optical crystals ("chips"). This includes cyberdeck components.
- Starblazer Adventures, based on the 1980's British Comic Book. The Random Key Items/Target of Objective random table lists Data Crystals as a possible target for an Item Mission.
- In Eclipse Phase cortical stacks are almost solid diamond, though mostly for its durability.
- Final Fantasy X has Spheres, which hold holographic recordings.
- The sequel expands upon this with the invention of the Garment Grid, which allows the party to use the skills and abilities of the person whose memories are captured on the sphere - translating into a Job or Class. This (of all things) actually becomes a major plot point when Yuna's usage of the Songstress Sphere actually awakens Lenne's dormant memories.
- The Halo series has these and uses them for storing artificial intelligences. Less complex data is simply transmitted.
- In StarCraft, the Protoss are an almost literal Crystal Spires and Togas society and use crystals as power sources and to store their thoughts and knowledge on. The Warp Prism transport in the sequel is actually described as a crystal computer, able to scan lifeforms and machines, convert them to energy and store the data in its databanks, then reconfigure them from energy back into matter.
- Ar tonelico has Hymn Crystals, which allows for songs (which are used as "magic" in the game) to be stored and later downloaded into Reyvateils.
- Star Wars: Droidworks features crystals that display messages when a laser is shined on them. A few show video clips from the movies.
- The Mega Man Battle Network series has these... Kinda. Unknown data takes the form of an 8-sided crystal, in three colors, green, blue, and purple. It's unknown whether or not this is actually crystalline though.
- Buck Godot: Zap Gun for Hire has "info points", though it's considered quaint.
- 8-Bit Theater has Dataspheres, which look like cubes. According to Red Mage, one has enough information to overflow the entire universe and possibly drive anyone who looks into it mad.
- In Orion's Arm, the "ultimate chip", doesn't look like a single crystal and was originally intended for use as a processor for very advanced distributed computing, can also store massive amounts of data, and is made of diamondoid, which is a crystal.
- BIONICLE: Memory Crystals.
- Shadow Raiders has the alliance control their Battle Moons (and all of their fleet) with crystal keys with the security codes.
- The reason for this trope is because crystals have been suggested as a storage medium for holographic memory.
- While all semiconductors function through quantum effects in their crystal structure, some technologies like Silicon on Sapphirenote more accurately reflect this trope.
- William Gibson reportedly thought that computer chips actually looked like this. Back in The Eighties!
- The actual semiconductor crystal part of any electronic device (the integrated circuitry) tends to be rather small, as being small is better for both performance and cost-effectiveness, and so they're not generally associated as being based on shiny crystals despite the fact that... they are.
