Angelbird AV PRO CFexpress B SE MK2 (256GB – 4TB)

Designed for professional photographers, filmmakers and content creators, the Angelbird AV PRO SE CFexpress B v4 MK2 is a high-performance memory card built around the latest CFexpress 4.0 Type B technology. Combining ultra-fast read speeds with consistent write performance, it is designed for demanding photo and video workflows, including high-resolution RAW recording and high-bitrate video production.

With capacities ranging from 256GB to 4TB, the AV PRO SE range offers flexible storage options for different production requirements. Higher-capacity models also deliver significantly faster sustained write speeds, making them particularly suitable for workflows involving high data rates and extended recording sessions.

CFexpress 4.0 Technology for High-Speed Performance

Built on the CFexpress 4.0 Type B standard with a PCIe 4.0 x2 interface, the AV PRO SE delivers maximum read speeds of up to 3,700MB/s. This high-speed performance enables rapid access to stored media and faster offloading of large files when paired with a compatible card reader and host system.

Ideal for professional cameras and demanding production environments, the card is designed to support high-resolution photography, continuous shooting and advanced video formats, including compatible 4K, 6K, 8K and 12K+ RAW workflows.

Consistent Sustained Write Speeds

For video production, sustained write performance is just as important as peak speed. Angelbird’s Stable Stream™ technology is designed to maintain consistent read and write performance across the card’s capacity, helping support reliable recording during demanding workloads.

Sustained write speeds vary by capacity, reaching up to 3,150MB/s on the 2TB and 4TB models. This makes the higher-capacity options particularly attractive for high-bitrate video recording and other data-intensive applications.

Choose the Right Capacity

The Angelbird AV PRO SE CFexpress B v4 MK2 is available in five capacities, with performance tailored to each model.

• 256GB: A compact storage option for photography and less demanding recording requirements, with sustained write speeds of up to 500MB/s.
• 512GB: Offers a balance of capacity and performance, with sustained write speeds of up to 1,050MB/s.
• 1TB: A versatile option for larger projects and demanding video workflows, delivering sustained write speeds of up to 2,100MB/s.
• 2TB: Designed for demanding production workloads, with sustained write speeds of up to 3,150MB/s.
• 4TB: Combines substantial storage capacity with the same high sustained write performance as the 2TB model, ideal for extended shoots and large media projects.
