Sony new CFexpress Type A memory cards feature bending and impact resistance to protect precious data

Sony Electronics Inc. announced it’s first CFexpress Type A memory cards, in both 80GB and 160GB, (CEA-G80T and CEA-G160T) as the most recent addition to Sony’s TOUGH specification cards. Both the CEA-G80T (80GB) and CEA-G160T (160GB) use the latest flash memory control technology to achieve write speeds as high as 700MB/si and read speeds as high as 800MB/si. The CFexpress Type A cards are ideally suited for high-speed continuous shooting of more than 1,000 uncompressed RAW still images, as well as 4K 120p movie recording at high bit rates with the Slow and Quick Motion function when paired with new Alpha 7S III, the company says.

The new CFexpress Type A memory cards are equipped with a heat sink to transfer heat generated by the card to the exterior when transmitting large amounts of data at high speed, using Sony’s original alloy with excellent thermal conductivity. The new CFexpress Type A memory cards feature bending and impact resistance to protect precious data, even when frequently changing cards in the harshest environments. They are up to five times more resistant to drop impact and up to ten times more resistant to bending, compared to CFexpress Type A requirement standards.

Optimized for the new CFexpress Type A memory cards, the CFexpress Type A/SD card reader (MRW-G2) provides SuperSpeed USB 10Gbps (USB 3.2 Gen 2) transfer speed, via its USB Type-C connector. When combined with a CFexpress Type A card, it allows users to transfer data approximately 2.8 times faster than with conventional media[vii]. The MRW-G2 card reader can be used with CFexpress Type A and SDXC/SDHC (UHS-I and UHS-II) memory cards.

CFexpress Type A memory cards and card reader will be available in September 2020. See below for suggested retail pricing:
