HDDs aren't written physically onto the plate. They flip magnetic fields. Anything relying on magnetic fields to store data is going to have a lifespan measured in decades, at best.
lol a drive continuing to work for 10 years doesn't mean that you could write to that drive, and have it sit in a drawer for over 10 years without the data getting corrupted.
Not true the charge in the cells also leaks so it well eventually become corrupt. You can see it in running SSDs in sections that are not written to a lot. The data sits there unchanged and the SSD has to do error correction and it slows down the drive.
did YOU read? we were talking about HDD
I don't think I've had a conversation that felt so much like Reddit on Lemmy until just now. when stored at a non-absolute zero temperature, magnetic discs are subject to thermal relaxation, even if they're kept at a steady temperature. besides the fact that you're going to pretend like we weren't specifically talking about the HDD plates, I'm not continuing this conversation because holy shit you're just trying to be frustrating
Highly presumptive on many fronts, as well as conflating the ability to reliably write with the ability to read data over the same time span. So, tell me of the connector on this hard drive that you have that is older than me. And what do you use that drive for beyond as a curiosity?
And there's that presumption. Just like the idea that a Faraday cage will block a magnetic field such as the earth's. And unless your suggestion is that the poster just has to store his archive on the moon or farther, it will still be subject to influence from another magnetic field. And everything I've read puts bit rot at about 1% per year, which means, even with aggressive error correction about 50% of the archive will be lost within 70 years without an active refresh of the media. That's not what's generally meant by archiving. If it was, we would be talking about a process and a commitment by third parties to keep some random person's archive intact for a century, unless what you're really trying to suggest is that the real trick to building an archive that will last over a century is to live even longer?
