Professional CFexpress 4.0 Type A Card

The OWC Atlas Pro 960GB card targets professional filmmakers, photographers and videographers who need reliable high-speed media for Sony Alpha and FX cameras. It is fully compliant with the CFexpress 4.0 Type A specification while remaining backward compatible with 2.0 devices. Buyers who need more than 960GB of capacity or who use cameras without a CFexpress Type A slot cannot use this card.

Capacity and Sustained Write Headroom

The 960GB capacity provides space for extended 8K video sessions and long RAW burst sequences. A guaranteed 400MB/s minimum sustained write speed prevents frame drops during high-bitrate recording. Peak write reaches 1700MB/s and peak read 1850MB/s for fast offloads. The card runs out of headroom when workloads exceed the sustained 400MB/s floor or when total footage exceeds the 960GB limit.

CFexpress 4.0 Type A Interface Limits

The CFexpress 4.0 Type A interface doubles the throughput of the 2.0 generation while keeping the same physical form factor. Maximum theoretical bandwidth is defined by the 4.0 specification, so speeds above 1850MB/s read or 1700MB/s write are not possible on this standard. The included Type A to Type B adapter enables full 4.0 performance only when paired with a compatible USB4 reader; older readers fall back to 2.0 speeds.

Questions about this item

Will the Atlas Pro CFexpress 4.0 Type A card work in my older Sony camera that only supports CFexpress 2.0?

Yes, the card is fully compliant with CFexpress Type A 4.0 specification and meets Type A 2.0 specifications for backward compatibility with existing devices.

How can I verify the card is delivering its rated 400MB/s minimum sustained write speed after setup?

Use the included Innergize health and performance management tool to monitor the card's real-time performance and health status on your computer.

Does the package include a card reader, or do I need to buy one separately to reach 1850MB/s read speeds?

The box includes a Type A to Type B adapter; a compatible CFexpress 4.0 card reader such as the OWC Atlas USB4 reader must be purchased separately to obtain maximum speed.
