Kingston is now shipping their new 64GB SDXC UHS-1 Class 10 memory card. SDXC stands for extended capacity and Class 10 means it can read at up to 60MB/sec and write at 35MB/sec.
In addition to larger capacities, SDXC cards allow for exponentially faster data transfer rates while maintaining the popular 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/sec., and 300MB/sec. in the future.
SDXC cards utilize the exFAT file system and are not backwards compatible with SDHC or SD cards.
The Kingston SDXC UHS-1 Class 10 will be available in stores late this month, to retail at about $500.
