These, if flash memory, do have a definite wear out mechanism,
although they do try to avoid writing to the same spot, even if the
software does, to mitigate this.

Correct. SSDs are an exception. They contain "leveling" software that makes
sure the disk is written to evenly. The Crucial disk I use is spec'd at
about 40TB of total writes.

For most usage scenarios the theoretical lifetimes of modern SSDs are
longer than HDDs.
