CF Card failure - a bit different

I’ve seen more CF card errors now, with UDMA 6 and 7 cards then the last 8 years. I have about 140GB in many different sizes and brands and never had any card error in the last 8 years… What’s wrong? Can it be an issue with Magic Lantern? Or maybe we are storaging next to our cell phones and radiation affects this new cards. Or is it just an issue with new card readers and USB 3.0 thecnology. Any ideas?
