Lexar Professional GOLD CFexpress 4.0 Type A 640GB – VPG-400 with up to 1800 MB/s read and up to 1650 MB/s write

Capture high-resolution footage and speed up post-production with the Lexar Professional GOLD CFexpress 4.0 Type A memory card. This 640GB card supports CFexpress 4.0 (PCIe 4.0 bus) and delivers very high sustained write performance to handle demanding workflows, including 8K raw video recording. It also includes rugged protection and recovery tools to help safeguard your files in the field.

Performance for 8K raw cinema-quality capture

The card supports read speeds up to 1800 MB/s and offers very high write performance to record continuous, high-bitrate content. The product description lists a sustained write speed of 1400 MB/s to enable stable recording of commercial-quality video and stutter-free burst photography. Note: some marketing lines in the original description reference write speeds up to 1850 MB/s while other sections and the product title list a max write speed of 1650 MB/s; the sustained and minimum write speeds stated in the specification remain consistent.

Guaranteed minimum write performance (VPG-400)

This card carries a VPG-400 rating, which guarantees that write speeds will not drop below 400 MB/s. That minimum sustained throughput helps prevent dropped frames and supports reliable recording of high-bitrate codecs in compatible cameras.

Rugged design for professional use

Lexar backs the card’s durability with an 8-point protection approach. The card is rated IP68 for dust and water protection and is tested to withstand temperature extremes, vibration, wear-out cycles, drops, shocks, compression, and bending. The description also references specific rugged metrics, including resistance to wear-out cycles, drop protection, shock and bend resistance, and pressure protection.

Workflow acceleration

When paired with a compatible CFexpress 4.0 Type A card reader (the Lexar Professional Workflow CFexpress 4.0 Type A Card Reader is sold separately), this card can dramatically reduce transfer times compared with CFexpress 2.0 cards. That faster transfer capability allows you to move media into post-production more quickly and maintain momentum on professional shoots.

Included software and warranty

Lexar provides a Recovery Tool to help retrieve accidentally deleted or formatted photos and videos. The card also ships with a limited lifetime warranty for added peace of mind during professional use.

Question: What does VPG-400 mean for my shoots?
Answer: VPG-400 guarantees a minimum sustained write speed of 400 MB/s. That minimum throughput helps prevent dropped frames when recording high-bitrate video and ensures more consistent performance in professional recording scenarios.

Question: How rugged is the card for field use?
Answer: The card features an 8-point protection profile, including IP68 dust and water resistance, and is designed to resist temperature extremes, vibration, wear-out cycles, drops, shocks, compression, and bending. These protections help the card withstand demanding shooting environments.

Question: Do I need a special reader to get maximum transfer speeds?
Answer: To achieve the fastest possible transfer rates you should use a CFexpress 4.0 Type A compatible reader. Lexar’s Professional Workflow CFexpress 4.0 Type A Card Reader (sold separately) is recommended in the product description to accelerate post-production and enable transfer rates up to twice as fast as CFexpress 2.0 cards.

Question: What recovery and warranty support is included?
