Angelbird AV PRO SE CFexpress B v4 Memory Card - 2TB

CFexpress 4.0 is the latest generation of the CFexpress standard, doubling the theoretical bandwidth of CFexpress 2.0 (which uses PCIe Gen 3). This card utilizes CFexpress 4.0 (PCIe Gen 4) for significantly faster read and write speeds.

For maximum performance and to manage firmware updates, using an Angelbird CFexpress B card reader is highly recommended. Standard CFexpress Type B readers may work, but might not achieve the full speeds or support all features.

Yes, the card is backward compatible with CFexpress Type B devices, but it will operate at the speed limitations of the older standard (e.g., CFexpress 2.0 speeds).

It's a safety feature that detects sudden power interruptions. The card immediately saves any data being written to its internal buffer and performs a safe shutdown, preventing data corruption or loss.

The card is rated for operation in extreme temperatures, typically from -25°C to +70°C (-13°F to +158°F), making it suitable for a wide range of environmental conditions.

Firmware updates are performed using a compatible Angelbird CFexpress B card reader connected to your computer. Download the latest firmware from the Angelbird website and follow the provided instructions.

Yes, with sustained write speeds of 3150 MB/s, this card is well-suited for recording 8K RAW and even higher resolutions like 12K+ RAW without dropped frames, provided your camera supports these formats and speeds.

Ensure the card is properly inserted. Check if the camera/device firmware is up-to-date and supports CFexpress 4.0. Try formatting the card in the host device (this will erase all data). Test with a different compatible device if possible.

Verify you are using a CFexpress 4.0 compatible card reader and a USB 3.2 Gen 2x2 or Thunderbolt connection on your computer. Ensure the card's firmware is up-to-date. Large file transfers are naturally slower than small ones.

Confirm that your camera or recording device is capable of writing at the sustained speeds required by your chosen resolution and codec. Ensure the card's firmware is updated. Check for overheating or low battery warnings on the host device.

Immediately back up any accessible data. Format the card using the host device. If the issue persists, the card may be damaged and should be replaced. Contact Angelbird support.
