Almost all laptops today come with built-in multimedia card reader which makes it easy to carry around memory cards in different formats. With the idea of new SDXC (Secure Digital eXtended Capacity) format standard materializing, it will replace the existing SDHC (Secure Digital High Capacity) format by early 2010. Dell, Lenovo and HP are working to roll out new laptop models with SDXC card reading support, reported DailyTech.
Earlier this year, at CES 2009, the SDXC standard was announced and now at the CES 2010 the 64GB SDXC memory cards would showed off. These new SDXC memory cards would support speeds as high as 300MB/s. The capacity of these cards could be available up to 2TB! Also, SDXC card readers would be backward compatible so that SDHC, SD andMMC cards are easily readable.
Intel's upcoming 32nm Westmere-die shrink based 'Arrandale' processors will pack 45nm Nehalem integrated graphics chip along with integrated memory controller. Also, the new chipsets will support the SDXC format cards through PCI-Express slot since USB 2.0 ports can't offer enough bandwidth. As of now, Intel has pushed its USB 3.0 supporting chipset plans to 2011.
At the upcoming CES 2010 show next month, we can expect to see loads of gadgets and laptops supporting SDXC memory cards. However, SDXC cards may not support full transfer speed and won't come in 2TB capacity initially. One should also note that these cards would cost more than the high capacity SDHC memory cards. By mid 2010, this SDXC format would go mainstream amongst laptops.
