The American multinational announced the highest-ever capacity SD card at the International Broadcasting Convention in Amsterdam last Thursday, 11 September.
The announcement marks the first ever availablility of a 512GB SD card; the previous maximum size was 256GB.
The card is dubbed the 'SanDisk Extreme Pro SDXC UHS-I' and will be available at retail for US$799.99 at release.
Sandisk introduced its first 512MB SD Card a little over a decade ago.
The card isn't exactly aimed at the average Joe consumer; Sandisk said in a statement the new card is "deigned to meet the demands of advancing technology both in photo and video – with the advent of 4K video in many cameras and the increasing resolution and file sizes of images.
The SanDisk Extreme Pro SDXC UHS-I is able to read at 95MB/s and write data at 90MB/s. The device is also temperature, water, shock, and x-ray proof, and boasts a limited lifetime warranty along with bundled RescuePRO Deluxe image recovery software.
"The new 512GB SanDisk Extreme PRO UHS-I card offers incredible speed and capacity," Grant Petty, CEO of video post-production house Blackmagic Design, said in a statement. "Our Pocket Cinema Camera customers shoot in every type of circumstance and location, and get amazing wide dynamic range RAW images capturing the brightest highlights and darkest shadows at the same time. The additional capacity of the SanDisk Extreme PRO UHS-I card will extend the creative freedom for our customers shooting in RAW and open up the ability to use wide dynamic range RAW files with even more productions."
