Did they die pretty early on? Do you use USB port on a hub/PC/etc for power? If answers to both of those questions are YES, over the years in reading forums/comments/etc a common thread between them has been that rPi kills microSD cards, and the commonality between most of those posts has been the use of (low/unstable) power strictly off of a USB port of another device (instead of a wall adapter) Edit: I now see that geerlingguy addresses this elsewhere in the thread too, so he can add at least some anecedotal experience that drawing too much power from a poorly-powered rPi is a recipe for failed SD cards (Sorry if this is completely irrelevant- it may just be that if you write to your cards a lot they're dying from that due to endurance, like you said)
