Sandisk Unveils World's fastest 128GB SDXC Card

About eighteen months ago, SanDisk revealed the world's fastest SanDisk Extreme SD 32 GB SDHC Flash Memory Card SDSDX-032G 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.
