I know of 2 card failures amongst 4 pro photographers. Both appear to be related a low height drop onto a hard surface. I've had a few cards age out, they start getting slow to read/write, corrupted, eventually can't read them. No recovery tools work at that point. I've had x2 hard drives fail. One main and one backup, gave up the magic smoke. All in 10 years of shooting. Used to run Raid 1 on my backups . Lots of boot sector errors.
