It was my understanding (perhaps wrong?) that RW media

change to store the data, and that it takes significantly more energy
to induce the phase change than to induce a chemical change in dye
for write-once media. That's why it can't be written as quickly.
If it really works that way, one would reasonably expect RW media to
have *better* longevity than write-once media.

I'm not disputing your experience or those of others. I'm just trying
to understand *why* it has poor longevity, when the scant information
I have about how it works suggests that it should be better.
