Sony is increasing the speed of their SD card lineup with the new SF-G Series, which offers write speeds of up to 299MB/s, optimal for hi-speed continuous shooting and 4K video shooting.
Sony says that the new card's 299 MB/s write speed is enabled enabled by its "unique" firmware, which does not allow the card to decrease its data-writing speeds. The cards also feature a read speed of up to 300MB/s. Paired with a memory card reader, the cards can transfer large volumes and file sizes to a computer very quickly.
Available in 32GB, 64GB and 128GB capacities, the SF-G Series also feature water proof and anti-static capabilities. Additionally, Sony's free downloadable File Rescue software allows for the recovery of photos and videos, including RAW images and 4K XAVC-S video files, that may have been accidentally damaged or deleted.
The SF-G Series is planned to be available in Spring 2017.
Also in Spring 2017, a high speed SD memory card reader, MRW-S1 supporting UHS-II, will be available to for use with the SF-G series, enabling the fast transfer of data to a PC with a USB3.1 Gen1 Interface.
