The main point is that with a regular backup regime, it doesn’t matter if SSD will lose your data if unpowered for a long time… because a) they won’t be unpowered for a long time (there’s rotation happening here, not archival), and b) you’ll have already hopefully moved off any specific piece of media before MTBF, and if you haven’t, hopefully all your devices don’t fail at exactly the same time.
So yeah: SSD isn’t for archival purposes. But archival isn’t really what we’re after here, as backup of ALL data is a possibility. It’s not like we have a monk or vellum shortage to worry about.
