New storage card also allows faster file transfer
SanDisk announced that it has begun shipping its new 64GB Ultra SDXC card. The flash media can store approximately eight hours of typical HD video, and can transfer data at up to 15MB per second. Devices compatible with the new SDXC format have only recently been introduced, and include Canon's new VIXIA camcorders and PowerShot cameras. The extra capacity doubles that of the largest SDHC memory card.
SDXC cards are based on the new SD 3.0 specification and use a new file structure known as exFAT. In theory, the new spec makes possible SDXC cards of up to 2TB. They are not backwards compatible with SDHC readers. The SanDisk 64GB SDXC card is available for purchase immediately at the company's website and should retail for $350.
