If this type of failure isn't considered a threat, then I have to wonder why NAS systems feature it, and people pay money for it.
I suspect it isn't common at least partly because continuously powered-up drives suffer mechanical failures long before bit rot can even happen. But for disks that are on-the-shelf, unpowered archives, bit rot is likely to be more of an issue.
A huge amount of effort has gone into strategies for long-term data archiving for petabytes of data, from heavy creators of at least science data. I understand it ain't cheap. It would be interesting to see some strategic thinking that would apply to a home user. Again it may just be a matter of archiving to multiple drives, and then, after checksum verification on one, do a wholesale write to the others every few years. If so, then a tool to do that would be handy.
