I… think good old paper, metal plates and carved stones are better technology than this. Unless there is a way to store video and audio for that much long term technology, mechanical methods are far superior for photos and text.

Hardy ,

You mean my 2GB Kingston that I bought in 2007, that I rarely use anymore won’t last me 200 years? Damn…

MonkderDritte ,

That’s nothing. Fused quartz can last you billions of years.

I’m pretty sure my PGP keyring is bigger than that

N3M ,

Kinda funny, I was just writing about archival media this morning. Verbatim makes DVDs & Blue Rays that last ~100 years, and M-DISC makes ones that’ll last ~1000 years. And the Verbatim Blu Rays run ~$0.036 per gig.

I use M-Discs too

JokeDeity ,

Where can I read about the testing that goes into these claims?

N3M ,

I’m far from an expert, but anything on standards JIS X6257 / ISO 18630 would probably be a good start. It’s an open standard for 100+ year discs.

Otherwise probably best to look into accelerated aging studies. For technology that’s less that 100 yrs old to claim 100 or 1000 is a bit uncertain but accelerated aging is probably the closest to a best guess. I recall skimming over a third party lab saying Verbatim gold foil archival DVDs were estimated to last 30-120 years depending on storage methods and luck, but never saved the link.

jivandabeast ,

I’m sure storage environment matters though?

N3M ,

Oh yeah, stick it in the sun or a damp box and either will probably be bad in weeks instead of decades or centuries. But supposedly they’ll meet those lifespans good at room temp

As the old saying goes: What could a person need more than 8KB for?

delirious_owl ,
@delirious_owl@discuss.online avatar

32KB*

Somewhat better than this useless USB thingy (from Temu?)

Summary by Andisearch

Researchers have developed a new quartz coin that can store 360TB of data for 14 billion years. This is a significant improvement from the previous quartz glass storage, which could only store data for 300 million years. The technique uses femtosecond laser pulses to write data in the 3D structure of quartz at the nanoscale. This makes it possible to store the whole of human history in a small coin-sized device. The storage system is also very durable, able to withstand high temperatures. This technology could potentially serve as a means of archiving important information for future generations or even extraterrestrial beings.

future firmware updates are expected to include encryption features

Just use GnuPG. SMH

delirious_owl ,
@delirious_owl@discuss.online avatar

I don’t think that would fit.

Grass ,

what about physical damage. or emp or something. I feel like that will be a problem well before 200 years.

You999 ,

Mold is actually the biggest concern with the most popular archival format LTO. EMPs aren’t that much of a concern. Bit flips and bit rot are your main concerns traditionally when using flash for archival storage. It’s recommended if you go the flash route to keep your array hot (ie powered on) and use a file system with data scrubbing capabilities such as ZFS.

delirious_owl ,
@delirious_owl@discuss.online avatar

Is the ZFS header bigger than 8kb?

gregorum ,

An actual book stores more data than that and for longer. At that point, why not just etch the data onto a metal plate or something? 8K is only a few pages of text at 12pt. It could easily fit onto two sides of a small-ish metal plate, etched in 8pt or so, and it would last, potentially, for millennia.

Alexstarfire ,

This can be rewritten many, many, many times.

gregorum ,

What’s the practical benefit of that? If the point is long-term storage, rewriting isn’t a priority (or possibly even a need). And this isn’t designed for capacity.

LostOperative ,

It’s so I can exchange fart jokes with my great great great great grandson via a magic USB port a la The Notebook, assuming that’s how it works, idk, never actually seen the movie.

delirious_owl ,
@delirious_owl@discuss.online avatar

I usually update my backups with new TOTP or other cryptographic keys every few months. Sometimes every few days (when I generate new keys).

Olifant ,

I think the idea is to improve upon this tech so the capacity would become larger.

gregorum ,

It’s FRAM, which has been around for ages. The problem is its prohibitive cost— hence the 8k.

BruceTwarzen ,

Why even invent the car when horse so much faster?

gregorum ,

You wouldn’t use a car to race in the Kentucky Derby

Restaldt ,

Maybe you wouldn’t

homesweethomeMrL ,

You’d make a bunch of jockeys mad

JackbyDev ,

Fine, I’ll drive from the roof like a jockey

Dippy ,

I absolutely would

delirious_owl ,
@delirious_owl@discuss.online avatar

idk, its much more resistant to floods.

gregorum ,

Than an etched metal plate?

delirious_owl ,
@delirious_owl@discuss.online avatar

Yes.

gregorum ,

USB drives don’t mix well with water

delirious_owl ,
@delirious_owl@discuss.online avatar

Why do you say that? I’ve put several through a washing machine and gone swimming with mine. Electronic usually are fine with water. Batteries are not.

Just let it dry out before passing a charge through it, and it works fine. Not so easy with paper.

gregorum ,

Not so easy with paper.

I had suggested a metal plate, not paper.

@1984@lemmy.today avatar

Kind of hard to return this after 195 years if it fails.

delirious_owl ,
@delirious_owl@discuss.online avatar

Hopefully its open source and you get all the schematics needed to repair it

1984 ,
@1984@lemmy.today avatar

Just one small issue with that… I probably don’t live for another 195 years. :)

delirious_owl ,
@delirious_owl@discuss.online avatar

Oh, well, I mean your spawn

fubarx ,

The year is 2245. The heirs finally locate a working, antique reader that can handle the ancient USB key, hoping to find great-great-grandpa’s crypto-wallet or the pin-code to a long-lost Maltese bank account.

Instead, they find a 4-bit, VGA-quality scan of Miss October.

qjkxbmwvz ,

I would be surprised if you couldn’t get 8KB for 200 years out of standard flash simply by extreme duplication — 8GB/8KB means a million copies on one (very small by today’s standards!) drive.

Or is the failure mechanism something other than bitrot?

pastermil ,

FRAM module? Seriously?

cmnybo ,

Will the chip actually last that long though? I would have expected a ceramic package with gold plated leads, not a plastic SOP-8.
