DNA used to store data

It’s done that since the dawn of life. We just haven’t figured out the data format or the dependencies.

Doesn’t help that it is full of legacy code, riddled with old virus installers and has a limited number of executions.

Needs a bit of code maintenance, sadly the original author forgot to document things

riddled with old virus installers

A number of vulnerabilities exist, but as with any system, new exploits turn u all the time

and has a limited number of executions

Product MTTF is 70 years, with careful use it will often last longer

Lets hope ARM don’t get their hands on it, it will go from four instructions to thousands!

DNA decay – SiO2 do not – unless dropped on something hard:

October 29, 2021, scitechdaily.com: 5D Optical Storage: High-Speed Laser Writing Could Pack 500 Terabytes Into CD-Sized Glass Disc
Quote: “…
Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000 times denser than Blue-Ray optical disc storage technology.

Until you break it, that is

I’m glad I’m not paying for their central heating, as 190C sounds a tad over the top for a living room.

Glass? I’m not sure a super cooled liquid is really a “fixed” storage.

You do get a lot of ‘once-was-glass’ in igneous rocks.

Hummm, while it’s a really interesting idea, it makes me thing about all the issues related to the storage media ;)

I am pretty sure that a beautiful day of sunshine may corrupt such data, oh and radiations too, quite a few chemicals, ha and possibly time as well…

but still interesting reading. Thanks for sharing!
