Reasonably Fast Read / Write Speeds. Thanks to the 90MB/s read speed, large amounts of data can be downloaded to computer with minimal bottleneck. Its 40MB/s write speed is reasonably fast enough for general still photography (not continuous shooting) and basic video use.

Class 10 – UHS-1. When used with UHS-1 compliant cameras, the card offers max speeds.

Error Correction. Sandisk’s Advanced Error Correction Code engine helps to prevent errors that cause potential data corruption

Video Compatibility. While these cards technically offer accelerated minimum sustained write speeds that make them video-ready for consumer-grade use, we strongly recommend otherwise for professional use. 40MB/s is generally fine for HD video (still the likelihood of buffer bottleneck), but fancy marketing isn’t going to help you when you’re in the middle of a shoot and the memory cards can’t keep up.
