Considering all the wonderful products and advancements that are currently slated for 2010, next year is beginning to sound like a strange, mystical land filled with wonders and mystery like Narnia, or New Jersey. The next milestone is one that has been on the standards roadmap for a year, but looks to soon appear on mainstream devices.

The new SDXC memory card standard which was announced near the beginning of the year is all ready to begin replacing current SDHC cards in 2010. The new SD cards will support speeds as high as 300MB/s and capacities as large as 2TB (as opposed to SDHC which can handle up to 45MB/s and 32G capacity). On top of the size and speed of the new cards, the standard is also backwards compatible, so SDXC readers will be able to use SDHC, SD, and MMC memory cards as well.

DailyTech reports that Lenovo, HP, and Dell are already preparing laptops with SDXC support, based on Intel’s upcoming Arrandale mobile CPUs. The only thing that has kept vendors from offering SDXC readers in current laptops is that most SDHC readers are connected internally through a USB 2.0 bus. USB 2.0 can’t handle the bandwidth of the new cards, so SDXC readers must be connected through the PCIe bus. The new hardware designs are taking that into consideration.

These first SDXC enabled laptops are expected to be shown at the 2010 Consumer Electronics Show in January, a year after the new standard was announced at the 2009 CES.
