Flash memory card leader Sandisk has launched its highest capacity SD card – the 64 GB Ultra SDXC--to tap the demand for consumer storage and transfer of full 1080p High Definition video files.
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 -- up to eight hours of video with a 64 GB card. Because the SD 3.0 specification is so new, only a handful of devices currently support SDXC cards. However, the pace of new camera model introduction supporting the SDXC format is accelerating. Canon announced at CES 2010, that all of its new VIXIA camcorder models and PowerShot cameras are compatible with SDXC cards. Widespread adoption of SDXC is expected across a range of consumer electronic products including HDTVs, Blu-ray recorders/players, camcorders, cameras, mobile phones, navigation systems and computers. 

Currently available only  online at www.sandisk.com  for $349.99, the Ultra SDXC 64 will soon be sold by Indian retailers.  But do checkif your digicam or handycam  can take  the new SDXC -type cards.

For professional photographers, SanDisk recently launched a 64 GB  Extreme Pro memory card where the transfer speed is  6 times faster -- 90 MBPS to the Ultra's 15 MBPS... but one has to pay a stiff price for such zippy speeds ( see our earlier story: http://indiatechonline.com/sandisk-extreme-pro-compact-flash-31.php  )
