@swope @Aaron_DeVries I once saw a datasheet for an Intel SSD, which basically said it likes being run hot and stored cold, and that combination gave the longest data retention lifetime. Hot/hot, not so much.

If I remember correctly, that's because higher temperatures make it easier for electrons to escape from the floating gates. Which is bad for data retention, but as long as the drive is powered on the firmware can handle that by re-writing the data occasionally. But it also means deliberate erasures are easier and cause less physical damage, so the SSD degrades slower if it's run hot. And after enough use, that matters more than the effect of temperature on the durability of any individual write.
