We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

What is the Shelf Life of SSD’s? (alien.top)

Let’s say civilization collapsed and I still want to run all of my archived games and programs that are on HDD and tapes at good speeds for the foreseeable future. If I get myself a supply of SSD’s and store them in ideal conditions with no data, no power, and stored them in a lead lined container (for pesky cosmic and terrestrial radiation) how long before the components inside the SSD’s would degrade and become unusable. If anyone has any literature that discusses in detail the mechanisms and physics of different SSD’s that would be appreciated also!

This is not a question about how long data I put on the SSD’s will last.

Counterargument, you actually ARE. For example, the firmware is also stored on flash (albeit it's NOR instead of NAND as far as I know).

I have absolutely no clue how long NOR flash lasts, although I have heard anecdotally that it is much more reliable (and more expensive) than NAND. Hence why SSDs use NAND for mass storage, and use NOR for shit like firmware.

Is there any reason they won’t work after that amount of time?

Without that firmware it's not gonna do a whole lot lol. So I don't have an answer to your question, but I feel like it should also be considered.

NAND

I always assumed NAND stood for something. But it is flash that is literally like a NAND gate?

Modern NOR flash has an expected lifespan of 10-40 years depending on the part. This is established using accelerated aging models. This assumes that no unaccounted-for design or manufacturing flaws arise in that time.

Oh that's interesting and might be an issue with the OP's 50 year time line
