The 64GB card can store more than eight hours of high-definition video with recording speed of 9 Mbps (HD standard) or more than 18,000 12 megapixel images.
SDXC cards are based on the new SD 3.0 specification, announced at CES 2009, which makes it possible to manufacture SD cards with storage capacity up to 2 terabytes. The new 64GB SDXC card will have a 15MB/sec read speed and Class 4 speed rating.
Because the SD 3.0 specification was recently released, only a handful of devices may be immediately available that support SDXC cards. However, the pace of new camera model introduction supporting the SDXC format is accelerating.
Canon, for example, announced at CES that all of its new VIXIA camcorder models and PowerShot cameras are compatible with SDXC cards. Widespread adoption of SDXC is expected to occur across a range of consumer electronic products including HDTVs, Blu-ray recorders/players, camcorders, cameras, mobile phones, navigation systems and computers in the coming year.
The new card will retail for $350 U.S., significantly less than the $600 64GB SDXC cards announced by Panasonic last month which are also expected to begin shipping this month.
