What _is_ "the entire rated service life of the drive"?  I would be
surprised if it were not far shorter than the time I want to keep my
data.

Fair point - but stuck drives typically can be made to start another
time or two, enough to get one last read of their data.  Do SSDs fail
similarly, or do they just cross a line and go from "working fine" to
"completely dead" when their firmware decides it's had enough?  I would
hope they'd instead flip from "working fine" to "read-only", but I have
little faith such hopes would be realized.

I was recently quoted a factor of approximately 2.3x for SSD as
compared to spinning rust ($300 vs $132, for the same nominal drive
size).  For what that's worth.

Probably not.  But the storage density is somewhat higher.
