>Only if you use the time saved to write more data than you would have with a slower drive

Well, NVMe SSDs do get quite hot due to much higher data transfer speeds, and higher temperatures lead to faster flash memory degradation, although I have no idea how important it is in practice (probably on the order of an SSD dying in 10 years instead of 20)

Consumer NVMe SSDs only get to those higher temperatures if you're writing a lot more data than a SATA SSD or hard drive could handle. And such higher temperatures might at a stretch have a meaningful impact on the data retention time for data currently stored in the SSD, but won't meaningfully shorten the program/erase cycle count.

Flash has (much) worse data retention at higher temperatures, but endurance actually increases with temperature. So the optimal way to handle flash memory is mildly hot when written to (to increase endurance), but stored cold (to increase retention).
