Sony introduces "world's fastest" SD card with write speeds of upto 299 MB/s

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 "decrease data-writing speeds that contribute to the camera’s ability of successive high-speed shooting". They are also water-proof and anti-static.

Additionally, the company is providing a free downloadable File Rescue software which allows easy recovery of media, including accidentally deleted or damaged files.

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.

Normally every OEM will advertise as 300MB/s R/W speeds. It sounds fishy.

Advertised speeds are always way more than the actual speeds. Its like me saying, I can get 100 marks in the exam but never got that.

Such fast MicroSD would be nice for tablets and hybrid netbooks

And super-cool for users of Raspberry Pi ( and other such devices ) , if the claims are realistic

No word on pricing though ....

Ah... I was thinking why do we need such high speed for a SD card... (noob me)
You enlightened me, it will benefit for Pi. And probably Intel NUC too

Also for high-bitrate 2160p (or greater) video recording in small form factor cameras.

Actually in some high-end hardware, the advertised speeds can be smaller than the actual real-world values...

Certain high-end Intel PCIE SSDs has this. If I recall correctly, they advertised something like "2200mb/s read / 700mb/s write" but actually got speeds of around ~2700mb/s read and like ~1000mb/s write.
Perhaps they meant "minimum" write speeds for the original 2200mb/s and 700mb/s rating, but I'm not sure.
