For whatever reason the relationship between SSD data retention and storage temperature while said SSD is powered off seems to be some kind of esoteric knowledge when it's really simple: every 5C cooler your SSD is store at you double the data retention. So you roughly get:
4 years at 20C
8 years at 15C
16 years at 10C
32 years at 5C
Fridges SHOULD maintain temps below 5C. You're welcome anons.
