Short answer: University of Southampton researchers reported a nanostructured fused-quartz disc that can hold up to 360 TB and projected a 13.8-billion-year lifetime at 190°C. “14 billion years” is a rounded headline, and the lifetime is an estimate—not a result from a test lasting billions of years. The work is a 2016 research demonstration, not a verified consumer product.
What the “14-billion-year” quartz storage claim means
The University of Southampton’s Optoelectronics Research Centre (ORC) announced the technology on 18 February 2016. Its medium is fused quartz (glass) patterned with nanoscale structures by femtosecond, or ultrafast, laser pulses.

Southampton reported a capacity of 360 TB per disc. It also described the medium as having a practically unlimited lifetime at room temperature and gave a calculated lifetime of 13.8 billion years at 190°C. Popular coverage rounded that number to 14 billion years.

How 5D optical data storage works
“5D” does not mean five ordinary physical dimensions. The encoding combines three spatial coordinates with two optical properties of each nanostructure:
| Encoding component | What it represents |
|---|---|
| Three spatial coordinates | The structure’s position in three-dimensional space inside the quartz |
| Structure size | One additional encoded property |
| Structure orientation | A second additional encoded property |
The laser writes tiny, light-altering features in the glass. Those features change how light travels through the material and how its polarization behaves. An optical microscope and a polarizer can detect those changes and reconstruct the stored signal.

Southampton described three layers of nanostructured dots, with the layers separated by five micrometres. This layered arrangement is part of how a large amount of information fits inside a small, transparent disc.

Documents reported in 2016
By the February 2016 announcement, the researchers said they had recorded digital copies of the Universal Declaration of Human Rights, Newton’s Opticks, the Magna Carta and the King James Bible. The ORC also presented a 5D-encoded copy of the Universal Declaration of Human Rights to UNESCO at the closing ceremony of the International Year of Light in Mexico.
These demonstrations establish that named files and documents were written and read using the technique. They do not establish that any of those copies have survived for millions or billions of years.

Durability: what the evidence supports
| Reported point | How to interpret it |
|---|---|
| Practically unlimited lifetime at room temperature | Southampton’s description of expected stability under ordinary storage conditions; not a completed perpetual-storage test |
| 13.8 billion years at 190°C | A calculated lifetime estimate reported by Southampton; the source does not claim direct observation over that interval |
| Thermal stability up to 1,000°C | The figure in Southampton’s official announcement |
A secondary Futurism article used a lower temperature figure of 157°C. Because the university announcement is the primary source and reports 1,000°C, that official figure is the one to use when describing the 2016 claim. The differing numbers should not be merged into a single specification.

Why this is not a “quartz coin” product
“Quartz coin” is informal headline language from popular coverage, not a cited product name. The research describes a laboratory-made fused-quartz storage medium.
Southampton identified national archives, museums and libraries as possible users and said in 2016 that the team was looking for industry partners. The available announcement does not establish a current commercial product, retail price, consumer writer, consumer reader or partner program. Present-day availability therefore remains unverified.
Do not assume that a normal hard drive, optical-disc drive, generic laser or cloud account can write or read this format. The method requires the specialized femtosecond-laser writing process and optical readout used by the research team.
How it compares with ordinary archival media
The research supports a clear description of the quartz system, but it does not provide a like-for-like benchmark against hard drives, tape, conventional optical discs or cloud storage. A responsible comparison uses the relevant decision axes without inventing competitor numbers:
| Decision axis | 5D fused-quartz research medium | What a buyer would still need to establish for alternatives |
|---|---|---|
| Capacity | Up to 360 TB per disc, as reported by Southampton in 2016 | Capacity depends on the specific tape, disc, drive or cloud plan |
| Environmental durability | Estimated 13.8-billion-year lifetime at 190°C; thermal stability reported up to 1,000°C | Use the manufacturer’s conditions and test method for the particular medium |
| Write process | Femtosecond-laser nanostructuring | Different media use different recorders and workflows |
| Read process | Optical microscope and polarizer interpreting path and polarization changes | Reader compatibility is format-specific |
| Demonstrated maturity | Research demonstrations and recorded documents reported by 2016 | Assess deployed systems, error rates, support and migration requirements |
| Current availability | Not established by the cited announcement | Verify that a complete, supported system can actually be purchased |
What would be required for practical archival use
- A production writer: Research-grade femtosecond laser equipment would have to become reliable, maintainable and affordable for institutional workflows.
- A documented reader: Archives need hardware and software that can decode the optical signals decades or centuries later.
- Format documentation: The encoding scheme, file formats, error correction and metadata must be preserved alongside the bits.
- Migration and replication: Institutions would still make multiple copies and periodically verify them, even if the glass itself is exceptionally stable.
- Independent qualification: Long-term aging, thermal cycling, radiation, handling and read-error behavior would need standardized testing.
Bottom line on “memory that lasts forever”
The Southampton work demonstrates an ambitious archival-storage technique: femtosecond lasers place information in five encoded dimensions inside fused quartz, with a reported 360 TB capacity per disc. The striking 14-billion-year figure is a rounded version of a 13.8-billion-year lifetime estimate at 190°C, not a directly witnessed survival period. As of the evidence in the 2016 announcement, it is a promising research medium for institutional archives—not a commercially available “forever” drive.
