Technologically advanced CFexpress recording speeds

The BLACK CFexpress Type B card carries a Rated Video Performance Guarantee 400 (VPG400). As a result, it supports high sustained write performance and is suitable for continuous high-bitrate recording. The card delivers minimum sustained write speeds of 2040MB/s to ensure data writes consistently during long RAW or high-frame-rate captures.

Delkin states that the card can reach recording speeds up to 3220MB/s in certain capacities, making it suitable for professional BLACK-quality video capture. The VPG400 rating plus the sustained minimum write speed help prevent dropped frames and interruptions during long takes.

Streamlined workflow for faster offload

For post-production, the card supports offload speeds up to 3700MB/s, which reduces transfer time from card to workstation. Consequently, photographers and videographers can clear cards and return to shooting more quickly. Faster offloads also shorten turnaround time for editing and delivery.

Tested for compatibility

Each CFexpress Type B card undergoes extensive testing to confirm functionality and performance in current high-end hosts. Delkin built the card to meet the demands of broadcast, BLACK and photography workflows. Note that CFexpress Type B cards are not backwards compatible with CFexpress Type A, CFast 2.0, or CompactFlash hosts.
