Inquiry about SMART data and testing cards for possible failure

Hi,

I have a number of Extreme Pro cards, and was wondering if they store SMART data and if such data can be read?  Failing that, is there any way to determine whether a card is nearing or at end-of-life?  Does SanDisk have a test program for that?

If neither of those is possible, are there guidelines about how many times an Extreme Pro card can be used and reformatted in a camera before failure?
