Professional CFexpress 4.0 Type A card

The OWC Atlas Pro is a 512GB CFexpress 4.0 Type A memory card built for professional filmmakers, photographers, and videographers. It is designed for Sony Alpha and FX cameras including the a1, a7SIII, a7IV, a7rV, a9III, FX3, FX6, FR7, and FX30. The card delivers up to 1850MB/s read and 1700MB/s write speeds for fast burst RAW sequences and high-bitrate video recording up to 8K. Buyers needing larger capacities or different form factors such as CFexpress Type B native cards are not served by this model.

Thermals noise and power draw

As a solid-state memory card with no moving parts, the Atlas Pro operates silently and generates minimal heat during typical camera use or file offloads. Power is drawn directly from the host device slot or card reader, requiring no external supply. The card is fully compliant with the CFexpress Type A 4.0 specification and meets Type A 2.0 specifications for broad compatibility. No active cooling or noise management is needed in normal operation.

Sustained load behaviour

The card guarantees a minimum sustained write speed of 400MB/s, ensuring consistent performance during extended high-bitrate recording sessions. It is VPG200 certified to work with all Sony camera modes without frame drops. An included Type A to Type B adapter allows maximum offload speed when paired with an OWC Atlas USB4 CFexpress 4.0 Card Reader. The Innergize tool provides health monitoring, performance management, and field firmware upgrades for long-term reliability.

商品問答

How do I install the CFexpress 4.0 Type A card and Type A to Type B adapter in my Sony Alpha camera?

Insert the 512GB card label-side up into the CFexpress Type A slot until it clicks; use the included Type A to Type B adapter only when reading with an OWC Atlas USB4 CFexpress 4.0 Card Reader for maximum 1850MB/s read and 1700MB/s write offload speed.

What maintenance will the 512GB CFexpress 4.0 Type A card need over time?

Run the included Innergize tool periodically to check health, apply firmware updates and refresh performance; the card is rated for 400MB/s minimum sustained write speed and VPG200 certification for consistent 8K recording.

What limit appears first during sustained 8K recording on the 512GB CFexpress 4.0 Type A card?

The 400MB/s minimum sustained write speed floor is reached before the 1700MB/s peak, so continuous high-bitrate capture stays stable as long as the camera’s data rate stays at or below 400MB/s.
