The next-generation SDXC (eXtended Capacity) memory card specification has been announced at CES and promises to further seal the demise of videotape as the preferred storage medium for consumer and professional video acquisition as media card capacities rise and prices drop.
The new SDXC specification provides up to 2TB (2 terabytes) storage capacity and accelerates SD interface read/write speeds to 104MB/s (megabytes per second) this year, with a road map to ultimately deliver 300MB/s.
The SDXC specification, developed by the SD Association leapfrogs memory card interface speeds while retaining the world-leading SD interface.
SDXC is also the first memory card specification to provide 2TB storage without hindering the high-speed performance necessary for high-end photography and HD video recording.
The SDXC specification uses Microsoft’s exFAT file system to support its large capacity and interoperability in a broad range of PCs, consumer electronics and mobile phones. The exFAT system was designed for increased compatibility with flash media, from portability of data to interoperability with multiple platforms and devices on removable media.
