I think they just mean it won't naturally degrade over time, like other physical storage media might. Obviously if you really wanted it bad enough, you could physically destroy the data.
If the surface is a gold alloy, you don't really need to want it "bad enough" at all. Gold is a soft metal and unless you treat it with care, scratches will be common.
I think the idea of this thing is that it doesn't degrade over time the way something like paper or a more reactive metal will.
It can be scratched but that's easily prevented: put it in a plastic sleeve.

You can still make 3 or more copies of data, so only if the plates are damaged in exactly same spots, data wont be recoverable.
The demo video uses a low power torch, focuses on a single point on every other card, but moves around on the Totenpass, and they cut away while it's still cool enough the person recording can momentarily touch it.
Gold is a fantastic element in that it's extremely non-reactive, and therefore resistant to most other things. The problem with gold though is that it melts at relatively low temperatures and is pretty soft. Alloying with nickel gives it hardness and raises it's melting point, but it's still well within the range that you could just straight up melt this using a MAP gas blow torch like is used for plumbing or really any significant fire event.
Additionally, the other downside of gold is that is scratches very easily. Their FAQ makes it clear that this is still a problem for Totenpass. The only advantage I see to a Totenpass over and M-Disk is that a Totenpass doesn't require any specific hardware to read, but both after being created require archival quality storage and care to prevent damage to the media. You know what else doesn't require specific hardware to read and survives a long time with archival quality storage and care? Acid-free paper. And it's a LOT cheaper than Totenpass.
Is this a joke, or do they actually think there's a market for this?

Given that the testimonial is from “Chad”, I have to think that there is a bit of joke in here.
That said, maybe this was a weekend project they made, and they can monetize it relatively easily (not sure how, but I guess it is possible).

I see ads for emergency rations and even saw an ad for a while marketing a rugged USB memory stick that contains all of Wikipedia on it in case the Internet and society breaks down you can still look up how to do stuff.
If people are buying that stuff, they'll buy this I guess. Doesn't mean it's practical but they'll buy it.

Back in the mid-90s, consumer CD burning was pretty new. At the time blank CDs were about $1 each, but it wasn't uncommon for the disk to become unreadable in less than a year because of degradation.
There was however another option -- gold plated CDs. These were $10 each, but supposedly lasted at least 10 years without going bad.
My entire dorm floor shared the cost of one box, and we'd use it for our most precious files -- our MP3 collection.
I still wonder where that disk is and if it still works...

I don't know if it is intended or not, but the punchline makes it funnier. Indestructible disks are useless if/when they get lost.
I recently helped with a data recovery effort at our company, where he found(stashed in a warehouse) CDs with the source code to some of our earliest games. Dates on the CDs were around 1994-1998 era. And you know what? Those gold discs are all useless, completely unreadable. You know what still works? Those verbatim blue AZO discs, all of them read just fine 20+ years later. Of course treat it just as an anecdote, who knows what condition those discs were stored in over the last 20+ years, but yeah, all the gold ones we found were dead.
Mark has it, and no.
While we're here (archival storage), anyone already using M-DISC?
I feel like the best bet in the short term is to buy a new, ever-larger external hard drive every year and copy everything onto it, keeping the old one off-site.

I'd never heard of M-DISC before. [0] "Verbatim M DISC™ optical media is the new standard for digital archival storage. Unlike traditional optical media, which utilize dyes that can break down over time, data stored on an M DISC is engraved on a patented inorganic write layer – it will not fade or deteriorate. This unique engraving process renders these archival grade discs practically impervious to environmental exposure, including light, temperature and humidity."

I think they are readable in all drives, but only burnable by certain drives. Also, they are not manufactured in DVD anymore, just Blu-Ray. Still hoping for any anecdata from personal use; checking here: https://hn.algolia.com/?query=mdisc&sort=byDate&type=comment

Yeah M-DISC is probably the best way to store important data (i.e. for me mostly old photos). Hard drives still seem a bit scary to me, even if you have multiple copies. I.e. you accidentally drop it and all the data on it might be gone, or there is some technical problem with your PC and also gone... While on an optical disc once you burn it it's always there (unless maybe you use brute force to ruin it).
M-DISC user here. I cannot attest the longevity claims as mine are around 5 years old but we'll see. Unless you want to crowd fund an lto tape reader with friends and family, you don't have any other option.
I cannot believe nobody has mentioned 5D optical data storage. Much denser, designed to last 10 centuries.

Ask how well this worked out for Scientology, who set out to do this with L. Ron Hubbard's works. Their efforts were essentially for naught as they used a now deprecated type of LaserDisc. (https://www.thedailybeast.com/inside-scientologys-secret-bun... https://tonyortega.org/2013/08/31/the-history-of-scientology...)
This is why engraved stone tablets remain the standard storage medium for religious texts. Easy to read anywhere, especially if you use a burning bush for lighting.
They should come with a cave for storage, else wind will erode the inscriptions. Running water will destroy them too. Even the cave may collapse on it.
Oral tradition could be good too if only the authors would ever bother to add error correction. Unfortunately this revolutionary distributed tech is held back by lazy implementations.
A well formed religion might be thought of as an effective form of long term data storage. In that case Hubbard was on the right track even if his creation wasn't.
The entropy is pretty bad though, both in data and the interpretation of the data through medium translation.
Another example of long term data storage is oral folklore traditions. Some Australian Aboriginal myths, for example, are claimed to contain references to geological events that date back 40k years.

The geological events are actually backed up with real science. Australian Aborigines are the only human culture whose stories have withstood the test of time - tens of thousands of years, in fact.
The reason is, they used cryptographic techniques (in their kinship system) to validate the stories as they were told among differing tribes and identify alterations.

An example might be useful; it seems to me that religions inherently distort the message of their founders. For example, most of Buddhist teaching was developed long after the Buddha died. Christians have had multiple doctrinal conferences to determine what is the "true doctrine". Islam has been divided since shortly after the death of the Prophet.

I think a useful example is in the book "How the Irish Saved Civilization." The basic premise is that Christian monasteries isolated from the post-Roman disorder preserved knowledge and knowledge tradition that reemerged later. Stating this is not intended as unqualified praise for the book or to deny the role of Orthodox, Syriac and Islam in knowledge preservation or to say that the deconstruction of the Roman Empire was a bad thing.

Jewish scholarship has been refining its view of the Torah for literally thousands of years.
From what I can see here looks like they've also archived Hubbard's works using text and simple recording methods powered by solar and mechanical; https://www.scientology.tv/series/inside-scientology/archiva...
Are they for naught? All they need to do is have a handful of laserdisc players around; your average clever nerdy arduino-loving teenager could probably get one working in the space of a day or two, likely by cleaning optics and maybe doing some re-capping and lubricating this or that.
They are usually are controllable via RS-232 or IEEE-488 and output any of several video formats. All extremely common, well documented protocols. Due to them using analog(!) to store the video, they're remarkably tolerant of defects. As someone who grew up watching a lot of rental laserdiscs with family, it was impressive how much damage a beat up rental disc could have and still play fine.
Man, the memories from that. A laserdisc machine spinning up was the most sci-fi thing EVER to a young kid.

That will work great once the company fails and its IP is sold off to some faceless entity. Truly long-term storage would include a specification for building a device to read the data.

Additionally nowhere in the “whitepaper” does it explain how this smartphone-powered retrieval works. Presumably by attaching a lens to the camera, but then the claim of “with only a smartphone app” is false.

Gold? That soft, malleable metal? Forever?
Sure, gold is somewhat resistant to chemical corrotion from just being left alone in a normal environment.. But how does it stand up to scratching, beating, bending and a forest fire ?
Scrolling down a bit brings one to a paragraph beginning, "The Totenpass is built from solid gold and nickel," which makes it sound like it might be an alloy.
yes, but it's never going to be a particularly strong one, this smells like they're mainly pushing gold because people tend to think of it as the pinnacle, magic material. Sure, it has very nice properties, but I fail to see long-term data storage as one of them.
Not up on my metallurgy, but I seem to recall that platinum has many of the same electrical and chemical advantages of gold. I think a few of the rare earth metals may also be better.
Gold is actually cheaper than a lot of these metals.

Silver-based photographs have lasted over a hundred years (as have actual books) so I think we're probably ok for archival media. There was a process I knew of years ago that replaced the silver in photos with gold or other metals, so that ought to nail it.

I've failed to find a nickel gold alloy with such a small amount of gold ("0.4g" according to the website) that still looks gold/yellow - 'white gold' which is a gold-nickel-palladium alloy has a magnitude more gold in it than that and nonetheless looks silvery.
I suspect this is a coated surface, with the coating being easily vaporized by a 405nm pulsed laser.

With the prices they're charging, $50 for the small one and $75 for the large, it has to be a coating, and a thin one at that.
The copy on this seems anti-cloud, but Backblaze and other providers mitigate bitrot with redundancy and things like RAID. I'm happy enough putting things on the cloud, since it will last longer than my on-prem hard-drives, which need to be spun up every few weeks to keep them working. Not to mention keeping my various SSDs in good shape by using them frequently.
I expect my SSDs to last 10 years since I don't do heavy writes to them often. Anyway, I do my ritual of buying a new spinning rust HD every 5 years and copying everything from my old drives for posterity of important data. Spinning platter HDs are my 'magnetic tape' for data storage.

Be careful with the lifetime of data on SSDs (though not the drive itself unless it SW bricks itself), if you don't have it powered and/or you don't give it a chance to read and rewrite data. Especially at elevated temperatures and/or if the drive has been used a lot, maybe also with higher bits per cell.
We've had consumer drives lose data after only a few months if it isn't accessed, though that was at 60+℃, so data should last some amount of time in normal conditions.

This is why it is still best to only have your OS and apps on SSD but all your data files on HDD (and backup). When you need fast access for some file, move it temporarily to the SSD.
Can confirm. SD cards can fall in 5-7 years due to cell voltage drift, and unplugged SSDs can have bitrot that overwhelms onboard ECC in less than a year.
HDDs don't fare substantially better, though: bitrot can happen in under a decade due to magnetic entropy/polarization decay.
Of course, your mileage may vary, and you may be lucky and get stuff off your 30 year old SCSI drive...

Odd of them to think that an object made of gold won't be stolen at some point in the far future and melted down into whatever shape its new owner deems fit.
The cheapest and safest long term data storage is stone tablets. Terrible information density and a logistical nightmare to move around though.

It's only about $25 worth of gold in today's prices. It's not a huge target.
It’s not about efficiency, think how many years a hard drive will last? 3 years. How many years a gold plate will last? thousands of years. Least reactive metal not for a reason lol

> How many years a gold plate will last?
A gold plate lasts until whoever holds it decides to remelt it. Or it gets destroyed in a fire. If you want durability I would recommend sturdy slabs of fired terracotta, preferably stored at a stable lagrange point.

It isn't a gold plate. It advertises itself as solid gold. It is in fact solid nickel, with 200-400 mg of gold peppered in. It's also at most 6.4 x 12.8 cm plate, which is tiny. If it were solid gold at 19.3 g/cm^3, it would have a thickness of 2.6 µm which is thin compared to your approx. 50 µm human hair. It is not, and therefore it is not solid gold.
If there is an ion blast sufficient to wipe all electronic storage devices on earth, won't the associated radiation also be fatal to a large percentage of the population?
No. People are more resilient than electronic storage media.
even if not, if all the electronics suddenly stopped a sizeable chunk of the population will die immediately or in a bit… i wonder how many safety protocols for objects with huge blast radius are dependent on electronics running continuously
In 200 years nobody will care about anybody currently alive in the planet, so why somebody would spend money in a permanent storage media.
If you do something relevant for the humanity, like Newton, Gauss, or Ampere, you won't need to save any kind of information by yourself. Sharing it with other people will be sufficient.

111.42 MB of storage is too little to end dependency on the cloud as they claim. Plus this is their "large" format that costs 75$ each. Finding the cost to store my 50+ GB family photo archive is left as an exercise to the reader :D
Jokes aside, I think there are better solutions from a home user perspective, I think that on their website they are targeting the wrong user base.
I hope the app is open source, or at least the method for reading it. Apps on the App store are very much ephemeral.
Yes. Code or documentation on this is crucial to make it really last.
edit: Found this on their website under "Every Totenpass is unique":
> Or you may choose to store thousands of documents or photographs to be retrieved at a later date using our proprietary reading technology and smartphone app.
So open source or well documented is probably not the way to go.

This is obvious BS... How could your phone possibly have the ability to read data that in encoded in the microscopic structure of gold?
It's like trying to read a CD with your phone. No software in the world could help you there.

Why gold? Seems awfully soft for something meant to last forever.
That's why it's mostly nickel.
Their FAQ still warns about scratches & how you have to use a micro-fiber cloth. I would think there would be some sort of metal you can both engrave very precisely but also not have to worry about it scratching like my eyeglasses.
Or else put a layer of plastic on the surface more permanent than your standard floppy lcd screen throwaway.

You could make it out of tungsten, but it'd be heavy, brittle, and an absolute bastard to machine. It'd probably increase the breakeven cost by an order of magnitude.
For protecting the surface finish of the gold, you'd probably want something like the polycarbonate cases you sometimes see used for rare or precious coins.

Encode your data in pyramids! Presence of a pyramid = 1, absence = 0. Hope the data format still makes sense in 8000 years!
Interestingly but perhaps not surprisingly, Moore's Law extrapolated backwards in time would be vastly more expensive than this.
We might get 10^14 more bits out of something that costs 10^-7 as much today, but that's only 21 orders of magnitude out of a suggested 1200 or so.
The universe only has 10^50 tons of mass, so it's meaningless to even attempt to describe what would that cost would look like.
I'm personally saving up to buy a bit of storage when it only costs a thousand universes or so.

Moore's Law says nothing about "bits stored" or "cost" of storage, and it makes no sense to extrapolate it before the invention of integrated circuits.
It's actually quite interesting to extrapolate our current exponential trends before ICs as a thought experiment. Kurzweil semi famously uses it to push his arguments: https://www.kurzweilai.net/ask-ray-the-future-of-moores-law
I do know what Moore's Law literally says. I thought it was fairly obvious I was generalizing, but yes the text as written is incorrect.
If you're not into the thought experiment, that's totally fine.

About half a MB per A4 side, according to a practical system described here:
https://www.extremetech.com/extreme/134427-a-paper-based-bac...
The 3.43MB@600dpi value does not include any redundancy and margin that a practical system needs.
Now let's build a block storage system that uses A4 paper as blocks :) Given the ubiquity of paper sheets, there should good sheet manipulation and archival systems around right ?

yes - I think that fits the bill pretty well too.
It runs into the same problem as long-term computer media, which is that the knowledge to read it may be lost. There was a period of time when nobody could read ancient Egyptian hieroglyphs, for instance, even though the hieroglyphs themselves survived.
Still better odds of legibility than this weird engraved chunk of gold-plated nickel, though.
This is a joke right?

Looks like a physical version of this diamond app that you hold a virtual diamond or something (worth nothing) but it's rare, so it costed like 10k to get it. Besides, there are at least 3 other metals or man-made materials that come to my mind, several times harder and more durable than gold & nickel. Just wandering aloud.

We will have microscopes in 50 or 100 years but there almost certainly will not be any working phones or apps as we know them.

Anything made of gold is a terrible idea for very long term storage, because if gold remains valuable,future humans will be incentivized to melt it down & use it for something else. After the late Bronze Age collapse the Egyptian government appears to have melted many things. You want long-term "permanent" storage to be in a material that people won't want to repurpose.
Hell, if it's good enough for Chad...
I can’t tell if this is a joke or not
This is dumb but I think I would pay for one of these when I quit playing Animal Crossing. A picture of the save file bits that I could keep forever. This is how I wasted X hours of my life sort of thing.
This idea is of course impossible since Nintendo would not give up the save file.

When their whitepaper is written in Microsoft Word and has citations to news articles, be wary!
Storage of Intermediate Nuclear Waste requires 10,000 years of storage a product like this might be useful for printing all the signage and procedure manuals that you’d want to keep with the waste.
This is an interesting idea, and it's neat to see companies thinking about long-term data storage. The density in this case seems rather low, which might limit the usefulness for most applications.

Cheapest ? No. Most effective ? No. Most persistent ? No.
They compare with disks but don't compare it with other materials such as marble.

Marble is too soft. Granite is better. I've made arrangements for my most important personal data (full name, birth and death dates) to be engraved on a granite slab when I die. This slab will be physically arranged alongside others, one for each family member, showing the relationships among people. This will be set up in a special location set aside for that purpose, outdoors safe from fire and building collapse. I expect the data to still be readable hundreds of years from now.
I can imagine that, in the near future, there will be headstones in cemeteries, with nothing on them except a QR code, which will require an app to scan, and a key to decrypt the data.
I wonder what future civilisations - where smartphones and encryption algorithms have been long lost - will make of that?
And we thought the Egyptians left us a tough one to crack!

There are occasional headstones with recipes on them. I love to imagine those aliens trying to figure out Aunt Naomi’s Spritz Cookies.
Until the property gets developed a couple decades later and they "move it".
Bring a bouldozer, load everything on a dump track and dump it in a nearby forest.
are those things your most important personal data? if i cared this much i’d probably prefer to leave a sentence or two rather than my proper name…
Marble reacts with almost anything, gold and nickel is the last thing to react. Elementary school chemistry: Gold is the least reactive metal
> Elementary school chemistry: Gold is the least reactive metal
Yet another case of elementry school chemistry over-simplifying and getting things wrong. Silver and platinum compete with gold, even if you stay within the realm of elementary school definitions of metal.

Let me guess, you don't own any silverware?
I have both goldware and silverware. But that's pretty much irrelevant, as they're alloys. Platinum is the least reactive of the things people recognise as metals.
You're right that silverware will tarnish much more quickly because of the addition of copper (and possibly other metals) -- so a bad example from me. But whilst pure silver is much more resilient to tarnishing, it will still slowly tarnish because even normal indoor air is prone to contain trace amounts of gasses with sulfur like hydrogen sulfide, which will react with the silver. Whereas I don't think pure gold does.
My guess would also be that most people who had school chemistry would order the silver, gold and platinum correctly in terms of their relative reactivity (and value) because this replicates exactly the order of fanciness of credit cards, record sales etc.

This. And I always laugh when people say gold has no value. It’s literally the best metal known to mankind. The reason why it’s not used much is because of its price.
There’s a lesson here in what “value” means.
But - try to handle some fine gold one day. It is lustrous, but also incredibly easy to dent - drop it and it’ll scratch like a 2010s-era phone. It is easy to work, but won’t hold its shape. If we had oceans of the stuff, we still wouldn’t use it to make a car or a laptop or a pistol or a building, it would take the place of lead in things like counterweights and radiation shielding, maybe home insulation or cooking foil, places where its softness and density aren't too much of a drawback but the low reactivity is beneficial.

Yes, of course, it’s not for all cases. One interesting thing though with gold is that it can be melted and reworked basically forever. This means that if you own gold today, your great-great-great-grandchildren could still be using it in 1000 years. This is not true of most materials. Gold’s value is basically the present value of all future uses.
> It’s literally the best metal
For some particular values of "best".
As gold is rather malleable (soft), these plates would probably scratch easily.

Why not just store it on the blockchain? That is guaranteed to be permanent and immutable according to web3 proponents.
Why is this ad voted to the front page?
Assuming you can still read the thing 10,000 years in the future.
Does anyone think this makes for a cool way to print a photo?
I immediately read this as "deathpass".

This should be made into NFT!

Tungsten FTW!
Platinum. more expensive, and we all know expensive means it's good.
The problem: its value. People will steal this.

Worst of both worlds, because the 0.4g of probably low-purity gold coated on to the thing isn't actually worth much. You can't sell it for any meaningful scrap value, but it looks like you could.
At first I thought this was a joke poking fun a cryptobros, but looking further it appears to be serious.
I think these guys really do believe this piece of jewelry solves huge societal problems.

More likely these guys believe this jewellery is going to solve their financial problems.
Given the scratch-ability, the suggestion that these things are practical for robust archiving is laughable.
But if they're handled carefully I can imagine them being useful for smuggling data across borders by hand or by mail. Which makes them potentially useful for money laundering, one time pads, and such - at least until customs services catch on to what they are.
There are better and less showy ways to do all of the above, but presumably you can print a cover photo or message with some embedded steganography, and the data content won't be visible to casual inspection - an application of sorts, I guess.

> The Totenpass is built from solid gold and nickel, which inherently resist destruction, never tarnish and will therefore outlive all other ephemeral forms of data storage, from hard drives to Cloud servers.
The FAQ:
> What can I do about a scratched card and can I get a replacement? Unfortunately, there is no remedy for scratched surface. During read back, information could still be recovered if the scratches are slight.
I'm thinking I'm missing something...
