Western Digital, the owner of Sandisk, today unveiled its SanDisk 1TB terabyte (TB) SDXC card prototype at Photokina, the trade fair for photo and video professionals. "Sixteen years ago we introduced the first SanDisk 64MB SD™ card and today we are enabling capacities of 1TB. Over the years our goal has remained the same; continue to innovate and set the pace for the imaging industry. The SanDisk 1TB SD card prototype represents another significant achievement as growth of high-resolution content and capacity-intensive applications such as virtual reality, video surveillance and 360 video, are progressing at astounding rates," said Dinesh Bahal, vice president, product management, Content Solutions Business Unit, Western Digital.

Since the introduction of the 512GB SanDisk Extreme PRO SDXC UHS-I Memory Card at Photokina 2014, Western Digital has proven it can nearly double the capacity in the same SD card form factor using proprietary technology.
