Lexar CFexpress 4.0 Pro Diamond R3700/W3400 (VPG400) 1TB – PCIe 4.0 speeds for cinema-quality 8K RAW

Capture cinema-quality 8K RAW video and speed up your post-production with the Lexar CFexpress 4.0 Pro Diamond R3700/W3400 (VPG400) 1TB card. This CFexpress 4.0 card uses PCIe 4.0 performance to deliver very high read and write speeds, built-in endurance features, and rugged protection for demanding shoots.

High-performance speeds for capture and editing

The card delivers up to 3,400 MB/s write speeds and up to 3,700 MB/s read speeds. It also provides a minimum sustained write speed of 3,200 MB/s. These measured performance levels support seamless capture of high-bitrate cinema workflows, including 8K RAW, and help accelerate file transfer and post-production tasks.

Workflow acceleration

Unprecedented read speeds dramatically reduce transfer times. For even faster media handling, pair this card with the Lexar Professional Workflow CFexpress 4.0 Type B Card Reader. When used together, those products can speed your workflow to roughly twice the speed of CFexpress 2.0, enabling quicker ingest, preview, and edit turnaround.

Endurance, reliability, and efficiency

The CFexpress 4.0 Pro Diamond uses advanced pSLC technology to increase endurance and data reliability. This approach helps deliver a longer lifespan—specified up to 30,000 TBW—while reducing power consumption and improving long-term data retention when compared to conventional architectures.

VPG400 rating for professional video capture

With a VPG400 rating, the card meets requirements for sustained video performance needed in cinema-quality workflows. Combined with temperature control technology and its fast sustained write performance, the card is designed to support continuous, high-bitrate recording such as 8K RAW video capture.

Built rugged for field use

The card incorporates multiple layers of protection. It is designed to resist:

Temperature extremes
Vibration
Wear-out (rated 12,000x wear-out resistant)
Dust (IP5X dust-proof)
Drops (rated 5 m drop-proof)
Shock
Bending
Compression (described as 7x more compression-resistant than SD cards)

These protections help the card survive the conditions commonly encountered during professional shoots and location work.

Recovery software and warranty

Lexar includes the Lexar Recovery Tool to help recover accidentally deleted or formatted photos and video files. The card also comes with a limited lifetime warranty, providing additional peace of mind for professional users.
