Sony Develop CFexpress Type B 128GB Memory Card

Sony has announced development of a new ultra-fast next-generation memory card, ideal for professional and industrial use. 

The CFexpress Type B 128GB memory card boasts super-fast read and write speeds of 1700MB/s and 1480MB/s. Sony has also said that 256 and 512GB models are 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.

The CFexpress Type B memory card will be on the market in early summer 2019. No pricing has been announced yet.
