I do have more memory and so swap does not seem to get used much at
all - but, I have not yet loaded the box up nearly as heavily as I
would normally do. In the list discussion, there was mention of an SSD
reallocating bad disk sections to unallocated space as a built-in
repair mechanism for the disc. I did leave a moderate amount of
unallocated space on the SSD, and if it really does work this way it
would be able to do a fair amount of repair before the disk is full
and thus extend the life perhaps for much longer. Not sure about this,
but it was easy to do with little impact on the disk size. Is there a
way to query the SSD to see if/how much repair has been done?

I think I'll keep it. I'm not a computer person so reliability and
minimum problem occurrences are high priorities for me. Given a
perhaps shorter SSD lifetime, I plan to make frequent backups of this
disc.

Regarding backups, I now have /home on a separate disk. The HD has a
LOT of data - is there a way to backup the SSD and the HD separately?
What I'd prefer is to make a clone image of the SSD without /home
[might fit on a CD/DVD] so I could get up and running quickly if it
fails.

Appreciate the help from everyone, as always...
