As someone who has continual issues with cards, here is what I do. I keep receipts, track the age of my cards and return them regularly on normal shopping trips. Also been known to buy identical cards 1 week and return the older ones 2 weeks later. I think the manufacturer builds then with an expiration date so you have to buy more. By doing this, no more lost photos------
Unbelievable.
Over the past decade, I've used Samsung Pro+ (no longer made) or SanDisk Extreme Pro cards. On travel, I take 10-15K photos every year. Never had a problem with either type of card. I do copy the day's photos to a laptop then external drive most every night, then reformat the card in camera. Never had a problem.
