SanDisk Corporation has introduced the SanDisk Extreme III 30MB/s Edition line of SDHC memory cards.

The company believe this speed sets a new record within SD flash memory cards. The cards will be available in 4, 8 and 16GB capacities and are designed especially to deliver a peak performance when used with the new Nikon D90.

The D90 is the industry's first DSLR camera to support the new memory cards, which feature a 50% speed boost from the previous 20MB/s cards. This means the SanDisk Extreme III 30MB/s Edition SDHC can record 39 images in continuous shooting mode at 4.5 frames per second with a file size of 6MB per image.

As well as the capturing, it's the offloading of high-resolution images to the computer that is important too. The new card does what it says on the tin, and can transfer images to a computer at up to 30MB/s, meaning you haven't got to wait an age to see them moved over.

Susan Park, director of consumer product marketing for SanDisk’s performance cards said: "The high capacities and performance of the SanDisk Extreme III 30MB/s Edition SDHC cards give users the freedom to shoot lots of high-resolution photos and video clips.

"The combination of our new SanDisk Extreme III 30 MB/s Edition SDHC card technology and the Nikon D90 camera maximizes performance.”

The SanDisk Extreme III SDHC 30MB/s Edition range of cards are expected to be available worldwide in September. US prices are currently standing at $64.99 (around £32) for the 4GB card, $109.99 (£55) for the 8GB and $179.99 (£90) for the 16GB. We'll get the official UK prices to you when we get them.
