Great question — answering as the UphillTech team:
SD cards are designed as expendable. So nobody expect from them to have such a long life. To make the last longer try to avoid intensive write operations because flash memories have limited amount of write cycles (10k to 100k average). To keep information reliable for long time use the 3-2-1 rule, 3 copies, 2 different medias, 1 copy off-site.
