How to store digital files for posterity? (hundreds of years)

How to store digital files for posterity? (hundreds of years)

I have some family videos and audios and I want to physically save them for posterity so that it lasts for periods like 200 years and more. This allows great-grandchildren and great-great-grandchildren to have access.

From the research I did, I found that the longest-lasting way to physically store digital content is through CD-R gold discs, but it may only last 100 years. From what I researched, the average lifespan of HDs and SSDs is no more than 10 years.

I came to the conclusion that the only way to ensure that the files really pass from generation to generation is to record them on CDs and distribute them to the family, asking them to make copies from time to time.

It’s crazy to think that if there were suddenly a mass extinction of the human species, intelligent beings arriving on Earth in 1000 years would probably not be able to access our digital content. While cave paintings would probably remain in the same place.

What is your opinion?

    Do you really think you are going to find a working CD drive in 100+ years? Try finding a working 8" floppy drive and a computer that can interface with one. They are only 50 years old and it’s quite a task to read an 8" floppy now.

    Data has to be transferred to new media as it becomes available if you want to keep it and be able to read it decades later.

      As long as it has a USB-A port, I think it will be good. We can’t seem to kill that one. ;)

        Kinda doubt that tbh think at most 15-20 years then we’ll look at USB A like how we see serial today. We’re still in the infancy stages of companies phasing it out even though it started like 8 years ago.

          you can physically wire A into C, it’s the same protocol. This won’t be broken like other adapters because neither device even knows about it

      yeah but the CD keeps being backwards compatible with DVD players, then Blu-ray, then UHD Blu-ray… these new 125tb discs are the same form factor again. i think we’ll have CD players way longer than tape decks

        I think CD is more or less at the end of its livecycle, most PCs sold today don’t even have a cd drive anymore.

            Sure, but getting the data from the disks through a game console sounds pretty not fun.

              The point is that even if CD or DVD drives aren’t produced nearly as much, there is still a market for newer drives that still support CDs and DVDs.
