CFexpress Memory Card Lexar Professional Gold 4 TB — LCXEXPR004T-RNENG

The Lexar Professional Gold CFexpress memory card with 4 TB capacity provides high-capacity removable storage for professional photo and video workflows. Designed in the CFexpress format, this card supports extended recording sessions, large still-image bursts, and rapid on-location backups. Its capacity is suited to capture long-duration 4K and 8K video, store large RAW photo libraries, and maintain multiple projects on a single media.

Advantages

The card combines very large storage space with the CFexpress form factor to enable sustained data capture and efficient media management. High sustained write performance reduces the risk of dropped frames during continuous recording and high-speed burst photography. Fast read speeds accelerate file transfer to editing workstations, shortening turnaround time for professional workflows. The robust design of the card supports repeated insertion and removal in compatible cameras and card readers.

How to use

Insert the CFexpress card into a compatible camera or CFexpress card reader following the device manufacturer’s instructions. Format the card in-camera or in a trusted reader before first use to ensure optimal file system compatibility. During recording or capture, monitor available capacity and file sizes; for long recording sessions, consider swapping cards or recording to multiple media to maintain workflow continuity. After capture, use a CFexpress-compatible card reader to transfer files to an editing workstation and verify file integrity before clearing or reusing the card.

Usage recommendations

For reliable performance, format the card in the device intended for capture, keep firmware for cameras and card readers up to date, and use high-quality CFexpress readers for transfers. Store the card in a protective case when not in use and avoid abrupt removal during data transfer. For critical shoots, carry multiple cards to distribute risk and enable immediate backups.
