Now, weâ€™re almost there! Can you imagine an SD card packing 2 terabytes of storage? Thatâ€™s what the SD Association is trumpeting now at CES 2009.
They call it the SDXC, for Secure Digital Extended Capacity, and it leapfrogs memory card interface speeds while retaining the world-leading SD interface. The SDA said SDXC provides up to 2 terabytes storage capacity and accelerates SD interface read/write speeds to 104 megabytes per second this year, with a road map to 300 megabytes per second.
Specifications for the open standard will be released in the first quarter of 2009. SDHC, Embedded SD and SDIO specifications will also benefit from the new SD interface speeds.
