Sony’s new CFexpress card can hit a blistering 1700MB/s

With the CP+ exhibition in Yokohama now in full swing, Sony has announced the development of a new CFexpress Type B card (CEB-G128) with an ultra-fast read speed of up to 1700MB/s and a write speed of up to 1480MB/s. This is three times faster than Sony’s fastest current CFast memory card (530MB/s) and five times faster than the fastest 300MB/s UHS-II SD cards available right now.

Photographers and videographers have been looking beyond the current SD/SDHC/SDXC standards for faster data capture, especially with the inevitable development of ever higher resolution stills cameras, the demand for higher bit rates, bit-depth and and frame rates in 4K video and the imminent debut of 8K video capture.
