Sony has unveiled new CFexpress memory cards that promise write speeds of up to 1.48GB/s and read speeds of up to 1.7GB/s. On shelves in the summer, the next-generation memory card, aimed at pros and for industrial use, will initially be available in a 128GB capacity, with 256GB and 512GB capacities coming later.

The new memory card is around three times faster than Sony’s fastest CFast memory card, which has a read speed of 530MB/s. To achieve this ultra-fast speed, the Type B cards make use of the CompactFlash Association’s latest PCIe® Gen3 interface. Alongside the new cards, Sony will also be launching a faster card reader (MRW-G1), which will also work with existing CFexpress and XQD memory cards.

See more information in the press release below and on the Sony website.
 



PRESS RELEASE

Sony develops CFexpress Type B memory card boasting ultra-fast read and write speeds of up to 1700MB/s1 and 1480MB/s1

  • Incomparably fast speed, designed for professional and industrial use, supports future evolution of digital devices
  • High reliability in extreme conditions thanks to TOUGH performance and smart software
  • New Sony CFexpress card reader, MRW-G1, takes full advantage of Sony CFexpress Type B’s high-speed performance
  • The Sony CFexpress Type B memory card and the CFexpress Card Reader will be in the market in early summer 2019

Sony today announced the development of the CFexpress Type B memory card (CEB-G128), a new ultra-fast next generation memory card2 that is ideal for professional and industrial use. With its super-fast speed of up to 1700MB/s (read) along with highly reliable toughness, this memory card supports the future evolution of digital devices.

Enhancing Sony’s high performance, value-added memory card line-up, the CFexpress Type B is designed based on a new specification which adopts the latest interface, PCIe®3 Gen3, standardised by the CompactFlash Association.

The Sony CFexpress Type B memory card offers a 128GB capacity, with higher capacity models of 256 GB and 512 GB planned for the future.

Incomparably fast

The Sony CFexpress Type B memory card is around 3 times faster than Sony’s fastest CFast memory card (with 530MB/s read speed). With a write speed of up to 1480MB/s, this card meets future requirement needs for secure industry data-recording or requirements from professionals to capture hi-resolution images or high-bitrate video.

With an ultra-fast read speed of up to 1700MB/s, even large-sized data files can be transferred quickly, when compared to existing memory cards. For example, when making copies or backing up large-sized data from multiple memory cards, transfer time will be dramatically reduced. This greatly improves work efficiency.

The new CFexpress Card Reader, MRW-G1, is optimised for Sony CFexpress Type B memory card and takes full advantage of the card’s fast read speed. This reader is also compatible with Sony XQD card G series and M series.

TOUGH performance

The Sony CFexpress Type B memory card has superior strength, surpassing the CFexpress standard by a factor of three, being able to withstand 70N of force in bend, and five times greater withstanding falls from up to 5m high.

The card is also temperature proof, X-ray proof, anti-static and has a UV guard so it can perfectly support usage in tricky or tough environments.

Peace of mind

Media Scan Utility and Memory Card File Rescue are available as a free download to Sony CFexpress card users.

Media Scan Utility is PC software that automatically scans your Sony CFexpress memory card every time you connect it to a PC via your MRW-G1 card reader4. The software keeps you informed of the condition of your card and lets you know if you’re nearing or have reached the flash memory limit.

Memory Card File Rescue eradicates every photographer’s worst nightmare – deleting photos accidentally and losing your precious work. The software recovers accidentally deleted files including RAW or high-resolution images and videos, so your work is safe from whatever obstacles are thrown your way.

The Sony CFexpress Type B memory card and the CFexpress MRW-G1 Card Reader will be on the market in early summer 2019.
