Lexar Professional CFexpress 4.0 Type A GOLD Series 256GB

The Lexar Professional CFexpress 4.0 Type A GOLD Series 256GB represents a generational leap in compact removable storage, leveraging the PCIe 4.0 x2 interface defined by the CFexpress 4.0 standard to deliver sequential read speeds up to 2000 MB/s and sustained write speeds up to 1700 MB/s. Built on a Type A physical footprint—identical in size to a conventional SD card—this media card targets Sony Alpha and other compact professional mirrorless camera systems that demand high-throughput recording without the bulk of larger Type B cards. The NVMe 1.4 protocol stack ensures low-latency command queuing, making the card equally capable of handling burst RAW capture and long-form continuous video recording without buffer stalls.

The GOLD Series designation reflects Lexar's top-tier endurance and thermal management engineering. An advanced controller with dynamic thermal throttle management maintains performance consistency even during extended 8K RAW or Cinema DNG recording sessions under elevated ambient temperatures. The card incorporates SLC write caching with a substantial pseudo-SLC buffer, transitioning gracefully to full TLC write mode so sustained throughput never drops below rated minimums—a critical reliability characteristic for broadcast and cinema production environments where dropped frames carry significant operational consequences.

With a rated TBW (terabytes written) specification appropriate for multi-year professional deployment, the GOLD Series 256GB is positioned for field journalists, wildlife cinematographers, and corporate media production teams who cycle through intensive daily recording workloads. The card is backward compatible with CFexpress 2.0 Type A host devices, providing investment protection for mixed-generation camera fleets, while forward compatibility with CFexpress 4.0-certified readers enables full-speed offload at editing workstations, accelerating ingest pipelines in time-critical post-production environments.

Ideal for

• High-frame-rate 4K/8K RAW video recording on Sony FX and Alpha series mirrorless cameras in broadcast and documentary production
• Continuous burst RAW stills capture for sports, wildlife, and photojournalism assignments requiring deep buffers and rapid card clearance
• Field ingest staging where cards are used as primary acquisition media and transferred at full PCIe 4.0 speeds to NAS or RAID via certified card readers
• Multi-camera corporate event or live production rigs where consistent, uninterrupted write throughput eliminates mid-shoot buffer saturation
• Aerial and drone cinematography platforms using compact mirrorless bodies where Type A form factor minimizes payload weight without sacrificing recording performance
• Post-production proxy workflows where fast sustained reads from CFexpress 4.0 readers feed directly into edit timelines, reducing offload-to-edit cycle time
