Excerpt: The SanDisk Extreme Pro UHS-II is the fastest SD card on the market (as of October 2014). This thing eats RAW files so fast you won't have time to even stop shooting. Buffering can create slow downs between shots but it's hard to fill a buffer when it gets cleared as fast as it does with this card. Highly recommended for those speed freaks and willing to pay a pretty penny.
Excerpt: We were on a birding trip in the middle of south america with no resources to turn to if there was an equipment failure and our gear needed to be trusted to work perfectly. This card worked great under harsh environmental conditions- very hot, very dusty, cars without shocks! All images were captured without a problem and the card was as fast as advertised. Worked perfectly for once in a lifetime pictures.
