Kingston Digital (http://www.kingston.com) is shipping a 64GB SDXC UHS-1 Class 10 memory card. SDXC (Secure Digital eXtended Capacity) is the next standard from the Secure Digital Association (SDA) for SD cards with storage ranging from more than 32GB up to 2TB.
In addition to larger capacities allow for exponentially faster data transfer rates while maintaining the SD form factor. The Kingston SDXC card is compliant with the SDA Memory Card Standard Version 3.01, UHS-1. UHS-1 stands for Ultra-High Speed Bus 1 which is the new architecture of SDXC cards designed to reach speeds up to a maximum transfer rate of 104MB/second and 300MB/second in the future.
SDXC cards utilize the exFAT file system and are not backwards compatible with SDHC or SD cards. Kingston’s offering has read speeds up to 60MB/second and write speeds of up to 35MB/second. The Kingston SDXC UHS-1 Class 10 will be available worldwide at the end of June and has a suggested retail price of US$499.
