The right thing is not storing data on a single 2.5 consumer SSD because the endurance on those devices are trash and the fail at super high rates.
They aren’t designed for a linux server, they’re designed for a disposable Windows laptop that will be chucked in the bin after a year or two. I’ve learned this lesson the hard way over, and over, and over again with these little cheap SSDs.
Most consumer 1TB SSDs with 600TBW should last at least within 10% or so of 600 days at 1 DWPD. If your ZQQTIAN or KingDonxi Amazon specials, populated with Micron QA rejects or SpecTek super economy grade or random e-waste upcycling chips failed in a month, that's on you.

What do you mean by "endurance"?
The only definition I found was the number of writes during the warranty time, and you're talking about a use case involving a very low volume of writes (i.e., save a file, keep it up for eternity).
This means that warranty time (more specifically, any failure mode at all beyond excess writes) is the most likely failure mode. Not writes, just the SSD being old.
Samsung advertises between 3 years and 10 years of warranty. The typical warranty of HDDs is between 3 and 5 years. Doesn't this suggest that buying you a decent SSD buys you at worst the same reliability?
How do I know an SSD is reliable or not? How do I know it's a consumer SSD or a real SSD? I'm particularly interested in drives which contain firmware that doesn't lie to the operating system about whether crucial operations have completed or whether errors were found. Is there a way to know?
I want to buy equipment that will last at least 10 years. It won't be heavily written but it will be heavily read. To me it feels like SSDs should last a long time for write-once read-many use cases.
Meh. The right tool for the job. That's engineering.
I hint at that by not caring about how the copy is made. Just that it is made... and that it's checked. Perhaps against some friends/additional copies if the situation allows for it.
Maybe all you have is an SD card or floppy drive, y'know? Each project or situation is different, I find dealing with the matters at hand more practical than dwelling over what I'd prefer.
Laptops would all be better off with four drives in RAID10 but we just don't do that.
