Sony Launches World’s Fastest SD Cards With Scorching 300MB/s Reads And Writes

Come springtime, Sony will release what it claims are the fastest SD cards on the market. It's new SF-G series will come in 32GB, 64GB, and 128GB flavors, with blazing fast write speeds of up to 299 megabytes per second along with slightly faster read speeds of up to 300 megabytes per second. What's more, Sony says the cards are equipped with a special algorithm that prevents a decrease in data write performance.

Having faster write speeds allows for longer continuous shooting of high resolution images and 4K video recording using cameras that support UHS-II. Speedy write performance also contributes to a shorter buffer clearing time so nothing gets missed during those rapid fire photo shoots.

"Available in 32GB, 64GB and 128GB capacities, the SF-G Series offers options that ensure high-performance, high speed and reliable shooting," said Viviano Cantu, Vice President, Product Marketing, Sony Americas Media and Energy Group. "As the continuous shooting of higher-resolution images and adoption of 4K video with DSLR and mirrorless cameras increases, the inherent need for larger, faster and more dependable cards becomes apparent. A longtime leader at the forefront of professional media, Sony has met these growing demands with the debut of the SF-G Series, which offers industry leading performance."

Sony also did users a solid by implementing fast read performance. That doesn't do anything for continuous shooting, but it does help with large volume and file transfers from the memory card to a PC. Being able to transfer files quickly is always appreciated when dealing with hundreds and sometimes thousands of photos.

To that end, Sony is also readying a new high-speed memory card for a spring launch. It's upcoming MRW-S1 supports UHS-II and will play nice with Sony's SF-G series SD cards. Then it will be a matter of choosing speed or capacity.

Sony did not say how much its SF-G series SD cards will cost.
