Sony has introduced the new SF-G series of SD cards, which it claims are the "World"s fastest" with write speeds of up to 299 MB/s and a read speed of up to 300 MB/s.
The company states that the quick write speed allows a longer continuous shooting of high-resolution images with UHS-II supporting cameras and a shorter buffer clearing time to help users better capture the moment.
Viviano Cantu, Vice President, Product Marketing, Sony Americas Media, and Energy Group said:
“Available in 32GB, 64GB and 128GB capacities, the SF-G Series offers options that ensure high-performance, high speed and reliable shooting. 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.”
The card uses Sony"s algorithm to " prevent the decrease of data-writing speeds that contribute to the camera’s ability of successive high-speed shooting". They are also water-proof and anti-static.
The cards will be available in Spring 2017 along with a memory card reader, MRW-S1, to enable transfer of data to a PC supporting the USB3.1 Gen1 Interface. The pricing remains unknown. You can learn more about the SF-G series here.
