“the medium is silica crystal, similar to optical cable, it’s highly durable. It’s also capacious: The technology can store up to 360 TB of data on a 5-inch glass platter.”

How hf can you have 5D space within 3D space? This sounds like marketing bullshit.
The 5D Memory Crystal stores data by using tiny voxels – 3D pixels – in fused silica glass, etched by femtosecond laser pulses. These voxels possess “birefringence,” meaning that their light refraction characteristics vary depending upon the polarization and direction of incoming light.
That difference in light orientation and strength can be read in conjunction with the voxel’s location (x, y, z coordinates), allowing data to be encoded in five dimensional space.
Oh, I get it now. It’s a five-dimensional mathematical space which is given by the three physical space dimensions plus the difference in light orientation and the difference the light strength.
It’s not strength, but rotation. Shoot a photon at the cube at a certain spot, you get data out of it. Hit the same spot in the cube with light that is polarized perpendicular to the first, and you get different data out of it.
Er… that’s what it sounds like, anyway…
Finally some worthy storage for memes!
Eat your heart out Ea-nāṣir.
Those aliens from the future will be so amazed when they find a disc with 360 TB of cat videos.
Not if I have anything to do with it
Oh good it can fit the next Call of Duty game.
Good luck finding a reading device for it in 100y, let alone 14 billion years. I doubt there will be a human civilization a few thousand years from now. :)
Remember how humanity had problems understanding the meaning of ancient egypt hyroglyphs from just a few thousand years back until The Rosetta stone was found and some really clever and dedicated guy put an awful lot of work into the translation? Good luck with JPG images or pdf documents or even ASCII text.
It’s OK to make fun of non-existing/ not yet market ready devices, no?
As long as as humans haven’t succumed to brainrot and still have capacity for math and logic, we can figure it out. It’s encoded, not encrypted.
The classic problem of long-term nuclear waste warning messages is about conveying information over cultural barriers. This is a concrete data type, not interpretation of vague contexual meanings from pictograms. Math and logic don’t change while cultures do. Images are far more retrievable than the meaning of an image.
Images would likely be the easiest possible thing to translate compared to more arbitrary codes since in that situation the output should be more easily decodable?
Also, there’s plenty of easy solutions to that.
I thought it would be hard to reverse engineer the compression algorithms used in JPEG images. Or even understand what the data structure is supposed to be to begin with.
I agree. If easy accessibility for future archeologists was the goal one could maybe use 1 or more 2D matrices of scalar values to represent monochromatic images. Or just etch the pixels of the image itself in the medium - like we do with microfiche.
Why would you need to reverse engineer the compression algorithm? The output can be viewed without that. I don’t need to know how you got to my party to have a good time with you :)
IIRC the thing is, you first present the key to the structure in some simple form, and then the rest of the data can be more complex.
Like the question how one would tell a future generation to not go to a dangerous place? Like a nuclear waste dump. Slightly different topic, I know.
Communicating with someone whose language and mindset doesn’t exist yet could be tricky. But math could be possible.:)
We still have Ford-Ts that are alive and kicking so pretty sure in a 100 years some museum will still have a working reading device for this. If this ever comes to market. Also the claim is just to ensure businesses that their backups on this medium will still be 100% readable in a couple of decades, even when the medium hasn’t been stored properly. Unlike tape that has a good chance to rot after 5 years. If it lasts a billion years it surely will survive some damp forgotten basement room for a few decades.
Fair. I agree with your arguments.
But I tried to clarify that I’m making fun of a not yet market-ready product (many are just fantasies to collect investor money and there won’t be a product ever.) and its exaggerated claims by pointing out that the sun will have died by then and no one cares about your excel sheets anymore. And more practical limitations like missing software and devices to read and understand the contents in a much shorter time frame. I exaggerated back if you will. ;)
But is it safe from the cats? 😼
glass shattering sounds
Not even cats are safe from cats.
Is anything, really?
“We are a technology licensing company”
This is good news from the point of view of being able to create devices that can read these crystals; as a comment on the linked site says:
The realistic lifetime of storage is the life of the last manufactured or surviving retrieval device.
Tbh my own personal use case is getting buried with all of my data and become some kind of data-“Tollund man” in the year 4000, when they dig up my data cube and study it endlessly.
I expect them to build a reading device to do this; it’s the least I would expect if they want to study the holiday I was on in Bergen, or completely misunderstand the two hotdog pictures I happen to have as some kind of fellatio training device.
“Myes, we do believe family structures were loosely organised around the remote picture beaming devices that used to be called “te levision”
I’m thinking of it the same way, and not having the readers be trade secrets but published specs is good for future digital archeologists.
For example, Dyson uses trade secrets instead of parents, so it would be harder to recreate their tech in the future.
It’s amazing to see all the effort we all put in perfecting technology to long-term store our porn. 360TB? I’d like to order 2 please.
Excellent, I will catalog my journals of my metamorphosis into a giant worm on these.
Giant worm that shits mind enhancing drug, to be more specific
“a 5-inch glass platter.” Found the weak point…
So, you’re telling me magnetic taps is not our real end solution? I’m not buying your new fancy ideas.
See, now this is the tech I would understand pouring billions into. Give every nation on earth a durable copy of the last 100 years of medicine, physics, biology. That’s what a reasonable ruling class ought to do.
At least give them to the nations which aren’t currently trying to ignore and undo the last 100 years of medicine, physics, and biology. (Sorry, United States.)
those are the places that most need it though
Eh, we earned it.
Once you have the tech fully worked out, the budget to make them is going to be cheaper. Easier for all nations to get their own
Waiting for the consumer reader and writer of those things, call me then
Totally. This is the data equivalent of a “new battery tech will revolutionise your phone” post.
Crystalline / Holographic storage has been hyped since the 80s… still not production ready.
@[email protected] 14,000,000,000 years
I will remember to check my lemmy inbox right after the earth gets eaten whole by the sun
And then again 13,000,000,000 years later.
This grinds my gears any time that a product is touted as lasting X time. Did you put it through a typical use case or scenario for that X time? No? Then you cannot definitively say that it will last that long.
Based on their bullshit statement, I can last 7 years pounding someone’s ass relentlessly without pause for any reason. Trust me bro.
The degradation of materials is pretty well understood. If it’s truly cut from a well known material with zero factors that could effect that degradation, it’s mostly safe to make en educated wish.
educated wish
I’ll have to remember this
“zero factors that could effect that degradation”
So in other words, only a completely unrealistic estimate can be made? After all, our sun is not going to be the same in 5 billion years, so unless the material comes along with a solution to maintain the material’s temperature (as per the manufacturer’s website the longevity is temperature-dependent) then 14 billion years sounds rather unlikely.
I don’t think the point is that you can sue them if it only lasts 13 billion years, but the under current conditions it’s projected lifetime is 14 billion years. Which is a very big number, meaning it’s pretty much guaranteed it won’t break in 100, 1000 or 10000 years.
You don’t take into account external factors like that. This is like saying “oh your watch battery will last an entire year? What about if I launch it into the sun‽‽”
You can put it on a spacecraft, and fling it at a bunch of star systems. Also preserving knowledge is still one of our hardest topic to solve. After the resources wars, what will computing even look like? Will we even make it another 3k years? How will we warn the next inhabitants of our pitfalls? Surely anything containing rubber gaskets will be ruined, all capacitors will have leaked. Any iron will have rusted.
Oddly specific fetlife bio
Unsure if joke or not, ha. I don’t even remember what I set in my bio for FL, its been a couple years since I set that account up…
You can stimulate wear on different types of materials and get a general idea of how long it would last. This isn’t plastic in a dvd.
I mean, people do predict things based on evidence. Galileo didn’t actually go to outer space and verify that the earth was going around the sun.
Didn’t they think in those days that your eyes sent beams out to touch whatever they were looking at?
I wonder if he thought his eyes were sending beams out into space.
Any volunteers for testing the claim?
I could go for a good ass pounding.
If you can get me safely to .999 C, slow me down, and get me back to Earth at .999 C, sure. The entire trip for me would only be about two years, provided a consistent 1 G of acceleration. Just please make it so that reversing acceleration doesn’t completely screw me, so my spaceship doesn’t have to do a complicated flip a bit after the halfway point on each trip. I’m certain that wouldn’t be good for my stomach.
Beyond that, the sun has about 5 billion years before we might not be able to starlift it back to a “younger” state, so The Earth and Venus may not exist at all if we don’t get our asses in gear for sustainable intragalactic life in the next century or so.
I am failing to connect the two time scales you mention.
The storage device can’t outlast the Sun.
there is some chance that earth may be ejected from the orbit into the space when the time comes, in which case this device could theoretically survive, but its users definitely won’t.
