I appreciate you laying it out like that. I've seen these NVME NAS things mentioned and had been thinking that the reliability of SSDs was so much worse than HDDs.

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.

[sandreas]

Isn't Amazon Glacier cloud based?

[dotancohen]

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