Sony has announced the new CFexpress Type B specification and latest CompactFlash memory card, which should be faster than anything on the market. The read and write speed of the new card is 1,700 MB / s or 1,480 MB / s. This is the fastest card from Sony, topping at 630 MB / s.
The new CEB-G128 memory card will be available in 128GB and 256GB memory versions, with an even larger 512GB version "for the future" planned. this is sold separately, is called MRW-G1 and optimized specifically for the type B card. It is designed to be durable by withstanding up to 70 N of bending force and allegedly withstanding drops from heights of up to five meters. The card reader also ships with Sony's Media Scan utility and Memory Card File Rescue, two free desktop apps that allow users to manage their new super-fast memory cards.
While microSD and SD cards are much more common on smartphones and cameras, CompactFlash cards are still used in high-end cameras. In a studio scenario where filming takes a long time and recorded files get bigger with the arrival of 4K content, a higher read / write speed is a big advantage over older, slower cards, even if those cards are smaller and fewer are cumbersome.
