Professional cinema card

The Lexar LCXEXP4512G-RNENG is a 512GB CFexpress 4.0 Type B memory card built for professional cinema and high-speed photography workflows. It delivers the sustained throughput that continuous 8K and high-frame-rate recording demands.

3000MB/s sustained write

The single specification that decides suitability is the 3000MB/s sustained write speed, which prevents dropped frames during long takes. Maximum read reaches 3600MB/s and maximum write 3300MB/s, but the sustained figure is the guarantee for uninterrupted capture.

Workflow integration

Pair the card with a CFexpress 4.0 Type B reader such as the Lexar Professional Workflow CFexpress 4 to offload footage at full PCIe 4.0 speed. The card frees the camera buffer for continuous shooting and removes the bottleneck between capture and ingest.
