New SF-G series reads at 300MB/s and writes at 299MB/s for 4K video

TAGS:

What Sony is claiming to be the ‘world’s fastest SD card’ has been announced! The SF-G series of SDXC cards, which will be available in 32GB, 64GB and 128GB capacity variants, are said to offer around 300MB/s read speeds and write speeds of 299MB/s. This means 4K video shot with mirrorless or DSLRs cameras can be speedily stored to the cards and then subsequently transferred (written) almost as quickly to computers or hard disk drives.

Such speeds are well in excess of most current cameras with the only stipulation being that your camera must support UHS-II U3 card types. For example, the current Sony consumer cameras can only record 4K video data at a speed of 100Mb/s (that’s megabits not megabytes). In other words, the cards are clearly future-proofed for 4K+ capable cameras that are yet to be launched.

File rescue software
Sony’s SD cards offer water proofing and anti-static protection, which help to keep your video and stills safe. However, if any accidental deletion of video or images happens with Sony’s free downloadable memory card file rescue software you can quickly recover deleted videos or images, including 4K XAVC-S video files and RAW images.

MRW-S1 fast card reader
To accompany its SF-G series of cards Sony is introducing a new memory card reader – the MRW-S1 – which should improve workflow efficiency after shooting by quickly transferring large amounts of data from SF-G series SD cards to computers. The MRW-S1 compact card reader has a built-in SuperSpeed USB (USB3.1 Gen.1) standard A port for cable-free connection, so that video or stills files can be copied faster than copying through the SD slot on a PC.

Availability
Sony has said that the new SF-G series SD cards will be available in stores in March 2017 and that the MRW-S1 card reader will be available during April 2017. Any RRP or SRP prices for either the SD cards or the card reader are yet to be revealed.
