The CFexpress 2.0 Type A memory cards are a slightly smaller and slower version of the widely used CFexpress Type B memory card. While Type B CFexpress cards are up to 2,000 MB/sMB/s im Glossar erklärt (1,600 Mbps) fast, Type A cards reach a maximum of 1,000 MB/sMB/s im Glossar erklärt (800 Mbps) according to the specification. The even larger Type C CFexpress cards can even be 4,000 MB/sMB/s im Glossar erklärt (3,200 Mbps) fast, but there are none on the market yet.

The new Sony CFexpress type A memory cards are equipped with a heat dissipator. This is made of a special Sony alloy with excellent thermal conductivity properties and dissipates the heat generated by the card during the rapid transfer of huge amounts of data. Users can therefore also film internal videos with 4K 120p over longer periods of time.

In accordance with Sony&s Tough specifications, the new CFexpress Type A memory cards have high flexural and shock resistance. The data is optimally protected even when frequently replaced in harsh conditions. The standard values for bending strength set for CFexpress Type A cards are exceeded by a factor of ten, and the impact value by a factor of five. In addition, thanks to their special internal construction, they achieve IPX7 against water ingress and IP5X against dust ingress - IP57 for increased durability.

Sony&s Memory Card File Rescue software for data recovery enables users to recover accidentally deleted RAW images and 4K video. In addition, Sony&s Media Scan Utility diagnostic software will be updated to allow users of CFexpress Type A cards to run diagnostics and receive alerts when the number of read/write cycles approaches the card&s limit.

The new CFexpress memory cards from Sony will cost 229 Euro (8ß GB model CEA-G80T) and 439 Euro (160 GB model CEA-G160T) and will be available from September 2020.
