Years ago I worked on an avionics project where we were storing data in
an NVRAM.
We had to write code to manage the wear-out in the cells and if I
remember correctly the wear-out was in the hundreds of thousands to
millions of writes before problems would occur.
I could not see normal usage causing wear-out unless someone were to
have some kind of bug causing a high write rate.
