About eighteen months ago, SanDisk revealed the world's fastest 32GB SDHC media card, pushing the format's data transfer speeds up to a rather lively 30 megabytes per second (MB/s). Since then, the SDXC standard has been let loose on the world, with the promise of theoretical capacities of anything up to 2TB and file transfer rates up to 104 MB/s for the UHS-I flavor and 312MB/s for UHS-II. While we're not quite there yet, SanDisk is again claiming the "world's fastest" crown with its new 128GB Extreme SDXC UHS-I card, which boasts read/write speeds of up to 45 MB/s.
Now that today's high end digital cameras are capable of churning out 30 megapixel images in quick succession, professionals and enthusiasts are driving media card manufacturers to produce storage that offers shot-to-shot performance to suit. SanDisk has responded to this call by creating an Ultra High Speed storage card claimed to be capable of transferring an hour's worth of full HD video in five minutes, or 500 high resolution photos in just one minute.

The new Extreme SDXC card also carries a Class 1 speed designation, which means that it supports real-time full 1080p video capture on UHS-I enabled host devices. It's temperature proof, water proof, shock proof, and x-ray proof, and benefits from advanced error correction engines for greater data integrity and card reliability. Even though there's an included write-protect switch to guard against accidental deletion of content, the new media card also comes shipped with a year's worth of data recovery goodness in the form of a RescuePRO Deluxe download.
The 128GB SanDisk Extreme SDXC UHS-I card is shipping now for US$399.99. There's an equally brisk 64GB version available, too, for $199.99.
