I read in the What's the life expectancy of an SD card? post SD cards are rated to hold data at something like 10 years sitting idle. I recall reading (not sure where) about re-energizing cards by occasionally inserting into a reader. Everything I read rates in read/write cycles and not physical decay. I'm wonder if buying a new sd card for every photo shoot would be beneficial if I could store the cards in a lock box? I was hoping for something much longer. Does anyone else agree with 10 years or maybe something more?
