A card that large is senseless for me at present and, as someone else pointed out, likely only really useful for 4K video capture at the present time. That said, there's nothing inherently wrong with the capacity. It's just in excess of what's actually needed for still photography, that's all.
At one time, I was standardized on 2G cards. Then my next generation of cameras appeared and I standardized on 8G cards. Then 16G. Now 32G. In a decade's worth of shooting with a bunch of cameras and cards of all these different capacities (over 300,000 exposures with Canon, Pentax, Panasonic, Nikon, Olympus, Ricoh, Sony, and Leica digital cameras),I have not yet experienced a single card failure. Not one damaged exposure.
I always buy quality cards. I always format them in the camera I'm going to use them in. After a shooting session, I copy their contents to my computer and reformat them. That's it, no secrets, no mysteries. I treat them the same as I do all my camera equipment, with respect and without abuse, but I use them a lot. They just work.
Anyone who is losing files, has problems with cameras or cards, etc, is being sloppy in their craft. Or abusing their equipment in ways that aren't sensible. IMO, of course.
