Well, the OP mentioned:
I have an SQLite database that will be used to store data every 3-10 seconds.
If we take a mean value of 6 seconds, that's 10 times per minute, or 600 times per hour, or 14,400 times per day, so that you reach 100,000 writes within a week or 1,000,000 writes in less than three months. That's not quite a decade.

I have duly noticed that you say "fully re-written" and I don't know what's the significance of "fully", but I suspect that a database file is completely rewritten each time it is updated (which of course doesn't mean that the card is fully rewritten, but the database file may have a size which is significant compared to the full card size).

Or am I missing something?
