Professional CFexpress 4.0 Type-B card

The Lexar Diamond Series 512GB CFexpress 4.0 Type-B card targets photographers and videographers who need PCIe 4.0 performance for high-resolution capture. It suits workflows demanding fast offload speeds and reliable sustained write throughput.

512GB capacity with 3200MB/s sustained write

The 512GB card delivers up to 3700MB/s read and 3400MB/s maximum write speeds. A VPG400 rating guarantees 3200MB/s minimum sustained write, enabling smooth 8K RAW video recording. Capacity runs out during extended multi-camera shoots or long-form 8K projects without offloading.

PCIe 4.0 reader required for full speed

The card reaches advertised speeds only with a PCIe 4.0 compatible CFexpress 4.0 Type-B reader such as the Lexar Professional Workflow model. It offers IP5X dust resistance, 5-metre drop proofing and 70N compression resistance. Buyers needing more than 512GB or a different form factor should consider other options.

Questions about this item

Will the Lexar Diamond Series 512GB CFexpress 4.0 Type-B card work in a camera that only supports CFexpress 2.0?

The card uses the CFexpress 4.0 interface and is designed for devices that support that standard; a camera limited to CFexpress 2.0 may not recognise it or may fall back to slower speeds.

How can I confirm the card is sustaining the 3200MB/s minimum write speed during an 8K RAW shoot?

The card carries a VPG400 rating, which guarantees a minimum sustained write of 400MB/s; for the full 3200MB/s you need a CFexpress 4.0 host and can verify throughput with benchmark software after recording.

Does the box include a card reader or only the 512GB memory card?

Only the CFexpress 4.0 Type-B memory card is included; a compatible reader such as the Lexar Professional Workflow CFexpress 4.0 Type B Card Reader must be purchased separately.
