SSDs are just limited write cycles whereas HDDs literally spin themselves to death. In a simple consumer NAS usage, like if this was just photo backup, that basically means SSDs will last forever. Meanwhile those HDDs start hitting borrowed time at 5-8 years, regardless of write cycles.

I have had two Sandisk 2.5 inch SSDS just suddenly fail. No warning that I could discern, and no way to recover afterwards. Both were while running Debian variants as a / partition, luckily I keep /home on a separate partition.

Any idea what that failure mode could have been? It worries me tremendously to keep data on an SSD now.

I had a Samsung 960 Pro nvme fail without warning, that was even more concerning

Then shortly after I had a BTRFS fail without failing Hardware on another drive

Just backup your stuff with 3-2-1 strategy and you're OK.

I'd recommend a combination of syncthing, restic and ZFS (with zfs-auto-snapshot, sanoid or zrepl) and maybe bluray (as readonly medium)

I'm considering Amazon Glacier for offline backup. Any opinions, alternatives, or other advice welcome.

Isn't Amazon Glacier cloud based?

Yes, I mean for off site backup. It's too late to edit that comment.
