If one flash memory fails or gets destroyed, you still have one or two left to retrieve from.
Even if a SD card is limited to 100,000 write cycles per cell, that is still good for at least 50,000 back up cycles (erase and write with new data) per cell. Assuming one back up cycle per day, that is 50,000 days.

I guess this is the new back up path I will be implementing soon.
