How does flash memory work? - Explain that Stuff
In addition, all semiconductor devices have long term reliability degradation. In the simplest terms, the transistors age and slow down. This is statistically compensated for with increased voltage, but sometimes the increase is insufficient for the aging. Sometimes the wires connecting transistors break down due to electro-migration.
These are all factors that go into the design and working life estimations of electronics

Thanks Mike - good info!
Still strange that the old SD card is problematic since it only got used about 100 times a year. But with that being said, the new SD card is working fine thus far with almost 100GB written/read without any problems.
Lesson learned.
