SanDisk Corporation recently announced that it has begun shipping the 64 gigabyte (GB) SanDisk Ultra SDXC card, the company's highest capacity SD card ever. With its 64GB capacity, up to 15MB/sec read speed and Class 4 speed rating, the new card, the company explains, “is ideal for capturing and storing massive 1080p High-Definition video files and then transferring them quickly to a computer.”
SDXC cards are based on the new SD 3.0 specification, which makes it possible to manufacture cards with storage capacity up to 2 terabytes (TB). The SDXC card's exFAT file structure helps consumers record long-duration HD videos. The 64GB SanDisk Ultra SDXC card can store more than eight hours of such video with recording speed of 9 Mbps (HD standard).
“SDXC is the successor to the popular SDHC card format,” said Susan Park, director, retail product marketing, SanDisk. “The 64GB SanDisk Ultra SDXC card delivers the speed and capacity consumers need for extended HD video recording and improved rapid shooting of still images. The card is an ideal complement for recently-announced SDXC-compatible cameras and camcorders.”
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 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. SanDisk® ImageMate® memory card readers are compatible with SDXC cards if the connected PC uses an operating system that supports exFAT.
