Kingston releases high-capacity high-speed SDXC memory card

Kingston Digital has introduced an ultra-fast and ultra-high-capacity memory card that incorporates the latest SDXC (Secure Digital eXtended Capacity) standard, capable of supporting up to two terabytes of storage.

The Kingston SDXC UHS-1 Class 10 card, the first from Kingston to support the new standard, provides 64GB of storage space, double the capacity of Secure Digital High Capacity (SDHC) cards. SDXC also supports a much faster data transfer rate than standard SD cards (presently offering a 60MB/second read and 35MB/second write rate, but with the potential under SDXC to deliver up to a 300MB/second rate in the future).

One of the leading benefits of the SDCX standard is its ability to allow continuous high-speed burst shooting in RAW format and hours of hi-def recording, notes Kingston. This is a boon to users of high-end high-resolution digital still cameras and high-definition camcorders.

The SDXC specification was developed by the SD Association, an industry trade group, and announced more than a year ago. Specifications were released over the course of that year and first products started entering the market in 2010. Earlier this year, Panasonic unveiled its first SDXC cards, available in 48G-byte and 64G-byte capacities.

The Kingston card fits into a standard SD slot, so is physically compatible with all cameras that support this standard. Since SDXC cards utilize the exFAT file system, however, they are not backwards compatible with SDHC or SD cards. A number of manufacturers, including Canon and Panasonic, are presently evolving their designs to include SDXC slots into their camera designs.

Other features of the Kingston SDXC storage card include: Support for CPRM (Content Protection for Recordable Media); a built-in write-protect switch that prevents accidental data loss; and support for Microsoft Windows 7, Windows Vista (SP1 or later), and Windows XP (SP2 or later).

The Kingston SDXC UHS-1 Class 10 will be available worldwide at the end of June and has a suggested retail price of $499.00.
