Re: [ts-7000] Flash wear level

[Larry <>]

It's been my experience that in general, flash takes longer to erase and write as it
wears. So at some point it is slower than spec, so it's considered worn out.
Of course, it will still work if the lack of speed can be tolerated. I don't know how long
it will continue to work as it gets slower.

As far as I know there is no way to get that information.
