As a counterpoint, I'm RMAing a Seagate HDD that I used for biweekly backups at the moment. It completed half of the backup as usual, there was a failure in the logs where it dropped out and now it constantly errors and clicks on startup and cannot be reformatted. Spontaneous failure with no data available, although I did neglect to try the freezer trick since it was a backup drive. SD cards are probably one of the less reliable mediums but I think I'd take two copies of important data on two SD cards over one on a hard drive if I was really worried about losing the data. Wouldn't be my first choice though!
