I agree with Jeff, look at the card first. Although I have had a number of quirky GoPro things, like not turning off and having to pull the battery, I haven't had any corruption issues. Not an option with GoPro, but I started recording to dual media a couple of years ago due to a general mistrust of media. The SDHC/SDXC/miniSd are all more fragile that CF cards, and as Jeff alluded to, I have more than my share of those . That being said, I don't know many people who put the demands on them that I do. I just got six new 32gb Lexar CF cards, and six 64gb SDXC's for the a sony video.
I bought two 480gb SanDisk SSD units for the Atomos products. Atomos understandably suggests SSD memory for most anything out if the studio environment.
