Indeed, the flash write endurance is actually significant higher at higher temperatures (I presume because of greater charge mobility) with modern flash. But data retention, naturally, gets shorter at high temperatures and quite a bit longer at low temperatures, and it can vary by orders of magnitude between temperature extremes. Again, I think due to the charge mobility effect.
