Don't expect it to survive a lifetime
I don't know what causes it (improper wear leveling? Cheap flash? Your guess is as good as mine), but those cards just don't last very long. More or less 1..2 years under a moderate usage in a mobile phone, with juggling files around, reciting video onto it, but not abusing it (as in opening a swap partition on it etc). Since the failure likely originates from the amount of write cycles, i'd expect it to die 5 times faster in a dashcam, or other aggressive use device. The reason i am posting this review now is because a 64gb card of this exact kind has just failed on me in my personal SGS7 a few days ago, on a road trip. As usual in this case, devices report the card as corrupted, and no amount of chkdsk/fsck?reformatting helps. Still giving it 3 stars, though, and the reason - as many fails as i've seen on those cards, on different devices, under different scenarios, i was always able to read back all the important data off the failed card.
