sd card lifespan
Actually the lifespan would be determined by how many times you write/format the memory card.
Industry insiders often refer to this as the number of “Program/Erase Cycles” or “P&E Cycles.” Almost all modern memory cards can withstand at least 100,000 Program/Erase Cycles, and some cards can withstand as many as 10 times more cycles than standard cards.
According to data on the following page, memory cards can hold at least 100,000 times of erasing/writing cycles on https://improvephotography.com/749/memory-cards-sd-cf-replaced-old-reliability/
