Delkin CFexpress Type B card Delkin 4.0 R3700/W3220 VPG400 2TB is a high-capacity removable flash storage card designed for demanding professional photography and video workflows. With up to 2 TB capacity and interface performance tuned for CFexpress Type B 4.0, the card delivers high sustained throughput for large RAW image bursts, long high-bitrate video recording, and rapid file transfers to workstations and external drives.

Advantages

Usage recommendations

For reliable performance, format the card in the camera before first use and periodically thereafter. Keep firmware on your camera and card reader up to date to ensure compatibility with high-speed transfers. Store the card in a protective case when not in use and avoid exposing it to extreme temperatures, moisture or physical shock. For critical shoots, consider maintaining multiple cards and backing up media immediately after capture.
