Designed around high-speed PCIe Gen 4 and NVMe technology, this CFexpress Type B memory card is engineered for compatible professional camera systems that require extremely high data throughput. It is particularly suited to high-resolution RAW photography, continuous burst shooting, professional video recording and large-scale media transfers.

Whether you are capturing fast-moving sports, wildlife, weddings, commercial productions or cinematic footage, the Lexar Professional DIAMOND is designed to provide the speed and capacity required for demanding creative workflows.

Up to 3700MB/s Read Speed

The standout feature of the Lexar Professional DIAMOND CFexpress 4.0 Type B is its read speed of up to 3700MB/s.

Professional cameras can generate enormous quantities of data, particularly when capturing high-resolution RAW images and high-bitrate video. Moving this data from a memory card to a computer or storage system can take considerable time when using slower media.

With compatible CFexpress 4.0 hardware, the Lexar Professional DIAMOND provides extremely high bandwidth for rapid media transfers. This can help photographers and filmmakers move large amounts of footage and photographs more efficiently.

For professionals working under tight production schedules, faster transfers can help reduce downtime between shooting, backup and editing.

CFexpress 4.0 Type B for Next-Generation Cameras

The Lexar Professional DIAMOND uses the CFexpress 4.0 Type B standard, providing the high bandwidth required by modern professional cameras.

CFexpress 4.0 utilizes PCIe Gen 4 technology and the NVMe protocol, enabling substantially higher data throughput than traditional SD memory cards.

This makes it well suited to compatible cameras capable of high-resolution still photography and advanced video recording. The increased bandwidth is designed to support demanding capture and transfer workloads.

To achieve the card's maximum performance, both the host camera and card reader must support the appropriate CFexpress 4.0 capabilities.

Up to 3400MB/s Write Speed

Fast write performance is essential when a camera is capturing large amounts of data at high speed.

The Lexar Professional DIAMOND CFexpress 4.0 Type B offers write speeds of up to 3400MB/s, providing substantial bandwidth for demanding professional capture workflows.

This is particularly valuable when shooting high-resolution RAW images, continuous bursts or compatible high-bitrate video formats.

For sports and wildlife photographers, fast write performance can help support rapid sequences. For filmmakers and videographers, high-speed storage can provide the bandwidth required by compatible professional recording modes.

Professional RAW Photography Performance

Modern high-resolution cameras generate increasingly large RAW files. While RAW provides photographers with extensive editing flexibility, these files require substantial storage capacity and fast write performance.

The Lexar Professional DIAMOND CFexpress 4.0 Type B is designed to handle demanding RAW photography workflows on compatible professional cameras.

With capacities from 128GB to 1TB, photographers can select the amount of storage that suits their shooting style and project requirements.

It is well suited to commercial photography, fashion, wedding photography, studio photography, landscape photography, sports photography, wildlife photography and editorial assignments.

High-Speed Continuous Burst Shooting

Sports, wildlife and action photographers often depend on continuous burst modes to capture fast-moving subjects.

Burst shooting can generate a large amount of image data in a short period, making storage write performance an important part of the overall camera system.

The Lexar Professional DIAMOND provides high-speed CFexpress 4.0 storage for compatible cameras, helping support demanding continuous-shooting workflows.

Whether photographing motorsports, wildlife, cricket, football, athletics or other fast-paced subjects, high-performance storage can help photographers maintain an efficient capture workflow.

Ideal for Professional Video Production

High-resolution video and cinema recording can generate enormous amounts of data. Advanced cameras may record high-bitrate formats, high frame rates and professional codecs that place substantial demands on storage.

The Lexar Professional DIAMOND CFexpress 4.0 Type B is designed for compatible professional video workflows where high-speed media is required.

Its combination of up to 3700MB/s read speed, up to 3400MB/s write speed and capacities up to 1TB makes it suitable for demanding applications such as filmmaking, commercial production, documentaries and professional content creation.

The exact video recording capability depends on the camera, recording format, resolution, frame rate and bitrate, so users should always verify their camera manufacturer's recommended media specifications.

Faster File Transfers for Professional Workflows

Once a shoot is complete, large quantities of media need to be transferred to editing systems, SSDs and backup storage.

The up to 3700MB/s read speed of the Lexar Professional DIAMOND can help accelerate this process when used with a compatible CFexpress 4.0 reader and high-speed host system.

Photographers working with large RAW libraries can move their image files more efficiently, while filmmakers can transfer substantial video projects to their editing workstation with less waiting.

This helps create a smoother workflow from capture to backup, editing, colour grading and final delivery.

Large Storage for Extended Production

Professional shoots can generate hundreds of gigabytes of photographs and video. Having sufficient onboard storage can reduce the need for frequent card changes during an assignment.

The 512GB and 1TB variants of the Lexar Professional DIAMOND provide substantial storage for extended professional workflows.

For filmmakers, commercial production teams and photographers working with large high-resolution files, higher-capacity CFexpress cards can provide more room for uninterrupted shooting.

128GB, 256GB, 512GB & 1TB – Choosing the Right Capacity

The 128GB version is suitable for shorter assignments, photographers who regularly rotate multiple cards and workflows where media is frequently backed up.

The 256GB variant provides additional storage for larger photography sessions and video projects.

The 512GB option offers substantial working space for professional shoots, while the 1TB version is designed for creators handling particularly large RAW libraries and extended high-resolution video recordings.

The right capacity depends on your camera's resolution, file size, recording format, bitrate, shooting duration and backup workflow.

Designed for Professional Mirrorless Cameras

Today's professional mirrorless cameras can combine high-resolution still photography with advanced video capabilities. These features can place significant demands on memory-card performance.

The Lexar Professional DIAMOND CFexpress 4.0 Type B is designed for compatible cameras supporting CFexpress Type B media.

Its high read and write performance provides the bandwidth required for demanding workflows, while its capacity options from 128GB to 1TB provide flexibility for different production requirements.

Before purchasing, users should confirm that their specific camera supports CFexpress Type B and the required CFexpress 4.0 performance.

Professional Storage for Filmmakers

Filmmakers can generate massive quantities of footage during a production. High-capacity, high-speed storage is therefore an important part of professional media management.

The 512GB and 1TB versions of the Lexar Professional DIAMOND provide substantial storage for longer recording sessions and large video projects.

This can be particularly useful for documentaries, commercial productions, cinema projects, interviews and other professional shoots where frequent media changes may interrupt production.

Built for Demanding Creative Workflows

Professional photography and filmmaking demand storage that can keep pace with high-resolution cameras and large media files.

The Lexar Professional DIAMOND CFexpress 4.0 Type B combines extremely high transfer speeds with multiple capacity options to provide a flexible storage solution for demanding workflows.

From capturing a critical sports moment in burst mode to recording high-resolution cinematic footage, the card is designed to support compatible professional camera systems.
