Who are we?
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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

I had SSDs go bad, and mechanical hard drives too. The major plus for me is that with HDDs, it is somewhat predictable, while with SSDs it has always been sudden (in my experience, at least).
However, there are more parameters to consider. The storage temperature, the relative humidity, to backup frequency, etc. In the end, if you want a 100% time proof solution without caring for the costs, engraving a crystal, storing it underground in a lead-lined container, is probably the surest way to go. Everything else is a compromise.
