Recording speeds and sustained performance

Delkin's fourth-generation (G4) POWER CFexpress Type B card reaches maximum write speeds up to 1700 MB/s. In addition, it offers minimum sustained sequential write speeds of up to 805 MB/s. These sustained speeds ensure continuous recording without dropped frames in data-heavy modes, and they support raw continuous-burst shooting without delay.

Furthermore, the card is approved for real-time broadcasting, which makes it suitable for live-production workflows that require steady, reliable write performance.

Streamlined workflow with fast offloads

The card uses a PCIe 3.0 interface to enable fast data transfers. As a result, you can offload footage and images at speeds reaching up to 1780 MB/s. This quick transfer capability helps you clear media faster and begin post-production sooner, making it practical for high-volume shoots and tight schedules.

Delkin reports extensive internal testing to verify performance and functionality in today's broadcast, cinema, and photography hosts. However, note that CFexpress Type B cards are not backwards compatible with CFexpress Type A, CompactFlash, or CFast 2.0 hosts. Always confirm your host device supports CFexpress Type B before use.
