American firm SanDisk has released the largest capacity SD card ever produced, cramming 512GB of storage space into the postage stamp-sized format popularly used in cameras.

Its launch comes almost exactly a decade after the company unveiled its 512MB SD card, with 1,000 times less capacity than the latest version.

The SanDisk Extreme PRO SDXC UHS-I memory card is designed for use by camera operators shooting 4K Ultra High Definition (3840x2160p) video, where a single minute of footage takes up 5GB of storage space.

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 new card can write at speeds up to 90MB/s. Transfer speeds of 95MB/s are possible.

It is also built for and tested in harsh conditions, with SanDisk claiming it is "temperature proof, water proof, shock proof, and X-ray proof".

The cards are available worldwide in capacities of 512GB, 256GB and 128GB. The 512GB Extreme PRO SDXC UHS-I card will be available for $799.99 (493).

The Secure Digital (SD) format was introdfuced in 1999 to replace MultiMediaCards and have been produced by more than 400 companies since then.

SanDisk was one of the three companies that were key to the development of the format, alongside Matsush.ita and Toshiba.
