Features: The SDXC (SD eXtended Capacity) memory card is designed to handle large volumes of data at high speeds and provide users with portable storage and speed for their camcorders or digital cameras. SDXC cards are able to handle significantly greater amounts of information due to two advances in technology. The exFAT file system enables the SDXC card to handle large volumes of data while the UHS-1 interface transfers movies, videos and picture with ideal speeds of up to 104MB/sec* *SDXC UHS-1 (Ultra High Speed Bus 1) memory cards can achieve the highest speeds only when paired with a UHS-1 device. For devices without the UHS-1 interface the guaranteed minimum data transfer rate for Class 10 will be 10MB/Sec.
