The card is waterproof, drop-proof and temperature-proof for outdoor shoots. Buyers who require higher sequential write throughput for professional cinema codecs or who need capacities beyond 512GB should consider other options.

The UHS-I U3 and V30 markings guarantee a minimum 30MB/s sustained write speed for 4K recording, while the A2 rating delivers higher random IOPS for apps and games. Maximum read performance of 170MB/s is achieved with a DDR200-compatible reader.
