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.

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.

[-] Olifant@lemmy.ml 44 points 6 months ago

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

[-] gregorum@lemm.ee 36 points 6 months ago

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

[-] Alexstarfire@lemmy.world 9 points 6 months ago

This can be rewritten many, many, many times.

[-] gregorum@lemm.ee 45 points 6 months ago* (last edited 6 months ago)

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@lemmy.world 12 points 6 months ago

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.

Why even invent the car when horse so much faster?

[-] gregorum@lemm.ee 2 points 6 months ago

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

[-] Restaldt@lemmy.world 4 points 6 months ago

Maybe you wouldn't

You'd make a bunch of jockeys mad

Print out 8KB on high quality paper.
Store in good environment...

[-] lowleveldata@programming.dev 7 points 6 months ago

How do I read that data back

[-] steal_your_face@lemmy.ml 61 points 6 months ago

With your eyes

[-] errer@lemmy.world 28 points 6 months ago

But 100 years we’ll all be mole people without eyes!

[-] lowleveldata@programming.dev 11 points 6 months ago

My brain doesn't have the decryption key. I'm no man in the middle.

[-] SexualPolytope@lemmy.sdf.org 6 points 6 months ago* (last edited 6 months ago)

Just get two men to stand on either side.

[-] notabot@lemm.ee 2 points 6 months ago

It's the same problem with a drive like this, or any long term archive, you either store the data unencrypted and rely on physical security, or make sure you store the encryption key and algorithm for the same length of time, in which case you still need the physical security to protect that instead. In both cases you need to make sure you preserve a means to read the data back and details of the format its in so you can actually use it later.

Paper is actually a pretty good way of storing a moderate amount of data long term. Stored correctly it's unlikely to physically degrade, the data is unlikely to suffer bitrot and it can be read back by anything that can make an image in the visible spectrum. That means you can read it, or take a photo and use OCR to convert it into whatever format is current when the data is needed.

[-] Swedneck@discuss.tchncs.de 7 points 6 months ago

just print something like a QR code in absurd resolution and read it in a document scanner, a single sheet of A4 should be able to fit quite a lot of data.

So your 8KB of data will last forever, but what about the firmware required to access it running on flash?

[-] Fester@lemm.ee 54 points 6 months ago

In 200 years, AI will hack it for you, but you’ll need a dozen antique dongles to get from USB-Z to A.

[-] pupbiru@aussie.zone 10 points 6 months ago

it does say it has a built-in serial console and raspberry pi

[-] skilltheamps@feddit.de 21 points 6 months ago

And the firmware inside that rp2040 is stored on plain old flash memory. So while the data may still be on the memory chip, the controller chip dies at just the same pace than every other usb drive - and then you can't access it.

[-] geneva_convenience@lemmy.ml 44 points 6 months ago

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

I'm going to get one for my favicon.

[-] pineapplelover@lemm.ee 4 points 6 months ago

What's the favicon?

[-] Distant_Foreground@lemm.ee 9 points 6 months ago

Then I said "I don't know, what's the favicon with you?"

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?

[-] N3M@reddthat.com 19 points 6 months ago

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.

[-] JokeDeity@lemm.ee 5 points 6 months ago

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

[-] N3M@reddthat.com 7 points 6 months ago

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@lemmy.browntown.dev 3 points 6 months ago

I'm sure storage environment matters though?

I use M-Discs too

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

https://futurism.com/memory-that-lasts-forever-new-quartz-coin-can-store-360tb-of-data-for-14-billion-years

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.

[-] Hardy@lemmy.ml 15 points 6 months ago

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

[-] cmnybo@discuss.tchncs.de 15 points 6 months ago

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

[-] aBundleOfFerrets@sh.itjust.works 13 points 6 months ago* (last edited 6 months ago)

The other flash chip storing program code for the rp2040 will decay before then making the longevity marketing dumb

[-] delirious_owl@discuss.online 3 points 6 months ago

Why you should buy two! /s

[-] 1984@lemmy.today 13 points 6 months ago

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

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

[-] You999@sh.itjust.works 5 points 6 months ago

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.

future firmware updates are expected to include encryption features

Just use GnuPG. SMH

[-] delirious_owl@discuss.online 2 points 6 months ago

I don't think that would fit.

[-] wesker@lemmy.sdf.org 6 points 6 months ago* (last edited 6 months ago)

The more you read is just gets wilder and wilder.

I'm admittedly interested now.

[-] delirious_owl@discuss.online 4 points 6 months ago

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

[-] pastermil@sh.itjust.works 4 points 6 months ago

FRAM module? Seriously?
