Tape presents its own share of problems. If not strored in some very particular conditions, like temp, humidity, and others that I can’t recall, they can stick to tbe adjacent layers, become brittle, curved, etc…
Comment on Unpowered SSD endurance investigation finds severe data loss and performance issues
SnotFlickerman@lemmy.blahaj.zone 4 days agoI think tape storage has the best longevity in offline data storage, but it’s been a while since I checked.

Strictly speaking, I think paper beats magnetic tape on longevity.
Unfortunately, it loses on data density.

If we are going by that metric clay tablets beat paper.

I was excluding media that are impractical for most people to use.
T156@lemmy.world 4 days ago
Paper would fall under that these days, wouldn’t it? You can’t just fit a word onto a punch card like the old days, and you’d need billions of the things go even start matching up to modern storage.

Depends on the threat model and how long do you need the data.
Worked on a place long ago, that anything they needed to save offline from more than a few decades where stored in microfilm, the expectancy there where they would last 80 to 100 years.
Anything else was pretty much tape.
You also take in account the technology avaiability. The more complex is to use, harder will it be to reproduce in the future. Even with tapes, you might want to copy the data to another tape/recorder every decade or two, to keep it on par with the technology.

I etch my data only metal slabs. The longevity is great, but the bits per pound is rough.

Just make sure you dont use sub-standard copper. Future generations thank you

At least you didn’t have to worry about Ruin manipulating it.

instructions unclear. I now have railroad spikes in my eyes for some reason.

M-Disc
Mustakrakish@lemmy.world 4 days ago
Technically does, but has a very high rate of failure on recovery, you need to recover the entire drive not just a section, and it can take days or weeks to read it back, vs mere hours.

As we all slowly step back from CD-RW, no quick movements… or was that all just a bad dream?

M-DISC’s design is intended to provide archival media longevity.[3][4] M-Disc claims that properly stored M-DISC DVD recordings will last up to 1000 years.[5] The M-DISC DVD looks like a standard disc, except it is almost transparent with later DVD and BD-R M-Disks having standard and inkjet printable labels.
That being said, that’s 100GB a disc. You can stuff a lot more on a typical hard drive, and I appreciate that people want to easily and inexpensively store very large amounts of data.

Yeah I believe tape is still king there. LTO is working on some 500+ TB tape for the future IIRC.
solrize@lemmy.world 4 days ago
The upfront cost of tape is excessive though. It wasn’t always like that. And LTO-9 missed its capacity target: it’s 18TB (1.5x LTO-8) instead of 24TB as planned. Who knows what will happen later in the roadmap.
