“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.”
You must log in or # to comment.
I’ve seen this particular revolutionary technology come by about once a year for the past two decades or so, so let’s say I’m not holding my breath and I will toss this one on the large pile of “bullshit tech articles”
If it is so easy to write to, seems it would be equally easy to erase
Bro has never used a permanent marker
A little bit of rubbing alcohol and it comes right off
Depends on the surface the marker was used on.
“easy if you have a diffraction-limited watt-scale laser” I guess
Intentional deletion is a lot different to entropy-caused bitrot
Open AI just bought out all the glass platter production. Not only will consumers not be able to store their data for 14gy, they won’t have anywhere to set down their drinks either
Sauce? Or sarcasm?
Really?
I been wooshed, sorry v.v
It’s like that these days. It’s hard to tell.
and just like every other storage medium, it will last for eons…and die about .5 femtoseconds before you have a critical need to pull data off.
It will not.
For real, what am I going to do when the sun swallows the earth in 4 billion years?
You may be entitled to compensation
Any number I could call?
prints article out
places it on an overflowing, ancient pile of documents of promising, science proved data storage methods that haven’t made it to public use yet
Nor ever will
I’m up to 45TB of actual used storage. I just want another tape analog. I want inexpensive, slow, long-term storage I can move off-site easily. This paying double to keep disks around and then moving them in boxes is just bad, and online storage is stupid expensive at those sizes.
Was running on Backblaze for years until they screwed around with my client enough that I can’t backup my NAS reliably. I’m not a company, I’m not going to pay the cost of my disks every year to store the content of my disks.
I’ve been considering for a few years standing up a 2u box in colocation.
Remember Memristors? They’re commercially available today, at 200 EUR per bit.
wow, sign me up for a couple of dozen terabytes of that!
I also remember people burning pitts on scotch tape, then rolling it up and reading it in 3d :)
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.
5D is the wrong term, the correct term is multiplex.
It is the correct term if you look at it from a Hilbert space point of view. You have 5 probe options (vector 5D) that give you 5 read options (vector 5D).
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.
You mean various levels of fucked up porn.
Yeah but they aren’t amazed by that, tons of porn in literally every civilization. But cat videos are novel
…but only one million years into it’s life span the human race is gone and aliens are unwittingly melting them down for raw material.
1 million years? You mean 200 top!
That’s the spirit! 👍
Denis Villeneuve nailed it years ago.
Similar concepts have been developed before, Microsoft and Southampton University were working on glass cubes with 3D laser etchings in the centre around 2015-16
(now divorced)
If you squint this is a weird shrine to a fictional marriage between Elvis and Britney Spears
I saw Shakira and that chef on YouTube who makes ornate sculptures out of chocolate and has a weird, fixed PanAm smile the whole time.
Okay yeah, now that you’ve said it I can see that too XD
Permanent storage. Like the Wayback massive and internet archive I hope will fully take advantage of these. As well as project Gutenberg. So much else. I’ve been waiting for something like this for a long time
Oh good it can fit the next Call of Duty game.
@remindme@mstdn.social 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.
Remember that CDs, CDRs, and so on were originally pitched as surviving 100 years. Turns out they last a highly variable amount of time but potentially as little as 2-3 years before they degrade, depending on the construction.
So I’ll just say, this is clearly a theoretical value.
Edit: Words.

CD-R and CD-RW discs use different methods of data encoding, and were never advertised as having similar longevity.
I mean…sorry, but this is wrong. Mitsui CDRs for example are still being sold on retail sites advertising 100+ (and sometimes 300+) year longevity. Similar to bitrot, internet rot makes it hard to find advertisements from the 90s, but I am comfortable that was true then too and not limited to “gold” high quality discs like Mitsui.
So it’s 2 to 3 percent of original estimate? That means it’ll last anywhere from 280 to 420 million years. Dead on arrival tech.
How can you be so sure they haven’t already done durability testing??
Because they weren’t invented in 1925? Any durability testing you do today is about assumptions where you accelerate the process for a year by heating it or exposing it to water or whatever will degrade it most to some factor above normal and then extrapolate. That extrapolation was wildly wrong with CDs and it could be with this medium too. Or it might last a lot longer. What they have not done is written to a bunch of them and stored them in a variety of ways for 100 years and concluded they last that long.
Oh, I see the confusion.
I was talking about the new media in the article, not CDs.
So… so are they. The new media has not yet been tested for 100 years because they were not invented 100 years ago
The ones with metal pigment are still waiting to fail, the ones that died used a cheap organic dye, coz profit. This is Silica (i.e. quartz, a long lived rock) with variances in polarization and intensity,( hence 5D when combined with a 3D Crystal))
OK generic marketing crap and will you have their special reader in a century, but it’s a solid way to project knowledge into the far future (gotta wonder if we need to re-examine some quartz crystals with this in mind ;}
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
