While out and about in a photo shoot I had this card fail on me. Luckily I'm a backup freak and was just starting out for the day so I only lost a few pictures. Card completely died and had to be sent back to Sandisk for a replacement.The whole process took a little over a week and communication was excellent so 5 stars on sandisk support.I know about memory so I always have multiple cards available and if I'm out for an extended time, spread my work out over cards to minimize risk.What about the average person who throws all their data on this disk and looses precious memories. Sure  they are at fault for not backing up their data. Unless you are shooting HD videos though, chances are you're not going to fill this card up in a day.Unless you either need the storage for HD video or something or your data is not important I'd say it makes more sense to just get several  16GB cards equaling 64GB at roughly the same or less price depending on brand.Again Sandisk support was great and they even asked if I needed data retrieved. I can't recommend this card though.
