Kingston's SDCA10 Class 10 UHS-I (Ultra High-Speed Bus, Speed Class 1) microSDHC card delivers 90 Mbps read and 45 Mbps write speeds; it reads up to 9x faster and writes up to 4.5x faster than standard Class 10 microSDHC/SDXC cards. UHS-I U1 technology lets users shoot Full HD video, 3D video and real time broadcasts without interruption and capture images continuously on their phones. Higher sustained write speeds ensure video integrity by reducing stutter and faster transfers free up user's time, especially when using Kingston USB 3.0 card readers.
