Personally, I still have more faith in harddrives than SSDs for data.
Why? I'm not skeptical; this is a sincere question.
So I have a SSD for an OS & programs drive, with data on a harddrive.
My sense is that with a hard drive, there's a real chance of getting
advance warning (via S.M.A.R.T.) when it's near failure. But with SSDs,
I've not seen or heard of any monitoring; failure is sudden, no
warning. Are SSDs S.M.A.R.T. monitored?
Yes, SSDs are SMART monitored:
$ sudo smartctl -a /dev/nvme1n1

No Self-tests Logged
However my mirrored backup drives are 1TB SATAs because that's what I
had lying around and speed is not important. Borg does compression and
deduplication so the size is plenty. I have an incremental nightly
backup, then a weekly, a three-monthly and a yearly and it all fits
comfortably. Obviously this depends on your usage and frequency of
changes to the data.

ok, thank-you Patrick.
