Sony is finally launching CFexpress 4 compatible CFexpress Type A cards for its Cinema Line and Alpha mirrorless interchangeable lens cameras, along with the MRW-G3 CFexpress Type A card reader.

The new[ CEA-G Series](https://www.sony.co.uk/electronics/xqd-memory-cards/cea-g-series) CFexpress 4-compatible CFexpress Type A cards achieve read speeds exceeding 1800 MB/s, more than twice as fast as earlier models, max write specs of 1700 MB/s, and provide a storage capacity of up to 1920 GB.

Sony is a bit late to the CFexpress 4 party, but better late than never (though, as it points out, as of July 2025 there are still no Sony cameras compatible with the CFexpress 4 standard. When using native CFexpress 4 cards, rather than these compatible ones, operation will be at CFexpress 2 standard).

The new cards are available in 960 GB (CEA-G960T) and 1920 GB (CEA-G1920T), and follow the VPG400 standard required for professional video recording. They also feature the TOUGH specification with approximately 5 times the drop resistance and 10 times the bend strength compared to standard CFexpress Type A cards , with boosted dust and water resistance (IP57), temperature resistance, X-ray resistance, anti-static, and UV resistance, making them usable in harsh environments.

Alongside the new cards is a new card reader. The [MRW-G3](https://electronics.sony.com/more/memory-cards-ssd/p/mrwg3) offers high-speed data transfer with CFexpress 4 and USB 40Gbps support, and features heat dissipation design to handle temperature increases during large file transfers, achieving high reliability and durability. 

## Pricing and availability

The 960 GB card will retail for approximately $584 and while the 1920 GB card is priced at $949. The MRW-G3 memory card reader will cost $149. All three new products are expected to be available by August.
