What, exactly, in technical terms, does this statement mean? If I've taken a life away, can you explain the rebirthing process?
Just kidding, but trying to make a point. The industry accepted figure of a 10 year lifespan for SD cards includes regular formatting. Unless you can somehow quantify your statement "take a life away", I don't think it's worth worrying about.
