Lexar Professional CFexpress 4.0 Type B Diamond Series 1TB

The Lexar Professional CFexpress 4.0 Type B Diamond Series 1TB leverages the PCIe 4.0 x2 interface to deliver sequential read speeds up to 3500 MB/s and sequential write speeds up to 3000 MB/s, positioning it among the fastest removable flash storage solutions available for professional imaging and cinematography. Built on an advanced 3D TLC NAND architecture with a high-endurance controller, the card sustains consistent throughput under prolonged burst capture sessions, eliminating the thermal throttling and write-speed drops that compromise critical takes during long-format productions. The Diamond Series designation reflects Lexar's top-tier binning process, ensuring only the highest-quality NAND cells are selected, resulting in improved reliability, lower error rates, and extended card longevity across thousands of record-erase cycles.

At 1TB, the card accommodates extended single-card recording of 8K RAW, ProRes RAW HQ, BRAW, and other high-bitrate codecs used in cinema-grade cameras from manufacturers including Canon, Nikon, and RED. The card's 1TB capacity reduces mid-production card swaps, maintaining workflow continuity on set and minimizing the risk of capture interruption during live events, documentary shoots, or multi-angle productions. Compliance with the CFexpress 4.0 specification ensures forward and backward compatibility with existing CFexpress Type B readers and camera bodies, while fully exploiting the doubled bandwidth of Gen 4 devices as they enter the professional market.

The Diamond Series is engineered with a reinforced aluminum shell that provides enhanced thermal dissipation compared to standard plastic-bodied cards, supporting sustained write performance during back-to-back takes. An integrated error correction engine and wear-leveling algorithm extend the usable lifespan of the NAND and protect data integrity under the voltage fluctuations and mechanical stresses common in field production environments. The card ships with Lexar's data recovery software license, adding an additional layer of protection for irreplaceable captured content.

Ideal for

• Cinema and episodic television production requiring sustained 8K RAW or ProRes RAW HQ recording at high bitrates exceeding 2 Gbps without frame drops
• High-speed sports and wildlife photography demanding rapid continuous burst capture at 20+ fps in cameras utilizing CFexpress Type B media
• Documentary and live-event videography where 1TB capacity enables extended single-card takes without interruption during unrepeatable moments
• Multi-camera broadcast productions offloading simultaneous CFexpress cards to NAS or RAID editing infrastructure via PCIe 4.0 card readers
• Post-production DIT workflows requiring rapid on-set data ingestion and verification at up to 3500 MB/s read speeds to minimize turnaround time
• Virtual production LED-volume environments capturing synchronized high-frame-rate reference footage from multiple camera units with consistent, predictable write performance
