SanDisk's 512GB Extreme PRO SDXC UHS-I memory card

World's highest capacity SD card revealed

SanDisk has unveiled the world’s highest capacity commercially available SD card, with 512GB of memory.

The Extreme PRO SDXC UHS-I memory card represents a 1,000-fold capacity increase in just over a decade – SanDisk unveiled its first 512MB SD card in 2003 – and is designed to meet the demands of professionals shooting video in 4K Ultra-High-Definition video or high-speed burst mode photography.

The card boasts write speeds up to 90 MB/s and transfer speeds up to 95 MB/s and the firm claims it is temperature proof, waterproof, shock proof, and X-ray proof, prompting them to offer a lifetime limited warranty on the device, which is the size of a postage stamp and will go on sale for $800 (£490).

Dinesh Bahal, vice president of product marketing at SanDisk, said: “4K Ultra-HD is an example of a technology that is pushing us to develop new storage solutions capable of handling massive file sizes. The 512GB SanDisk Extreme PRO SDXC UHS-I card is a tremendous advancement that enables professionals to reliably store more content on a single card than ever before.”
