The SF-G series is supposed to be the world’s fastest SD card and is designed for high-performance DSLR or mirrorlesscameras, offering up to 299MB/sii write speeds, contributing to longer high-speed continuous burst mode shooting for high-resolution images with cameras supporting UHS-II.
Sony said the SF-G cards will allow more effective continuous burst mode shooting for high-resolution images so long as the camera in question supports UHS-II.
Write speeds will also be of considerable benefit to the wide range of high-end DSLR and mirrorless cameras that are capable of shooting 4K quality video. Faster write speeds also mean a shorter buffer clearing time, when shooting fast-moving action.
The series’ read speed is reaches up to 300MB/s, resulting in faster and smoother performance when transferring large files across to other devices for editing and sharing.
Available in 32GB, 64GB or 128GB from March 2017, all versions of the cards are compatible with Sony’s free file rescue software, for recovering lost content. No word on pricing yet.
Alongside the SF-G series, Sony has also introduced a new memory card reader, the MRW-S1, due for release in April. It features an in-built SuperSpeed USB port for cable-free PC connection, so that your files can be copied faster than by using the slower SD slot on a PC.
