SanDisk Extreme Pro CFexpress® Card Type B - 128GB

Product Description 

Professional-Grade Storage for High-Speed Cameras

• The SanDisk Extreme PRO CFexpress® Card Type B 128GB is a high-performance memory card designed for professional and enthusiast photographers, videographers and content creators working with demanding cameras.
• Built around the CFexpress Type B format, it provides substantially higher performance than conventional SD memory cards, making it suitable for cameras that require rapid data transfer and sustained recording performance.
• With sequential read speeds of up to 1700MB/s and sequential write speeds of up to 1200MB/s, the card is designed to handle demanding photographic bursts and high-resolution video recording.
• The 128GB capacity provides a practical balance between storage space, portability and cost, making it particularly useful as a dedicated card for professional camera systems.
• SanDisk also specifies support for RAW 4K video capture with sustainable, low-latency performance, although actual recording capabilities depend on the camera, codec, bitrate and other system factors.

128GB Storage Capacity

• The card provides 128GB of nominal storage capacity for photographs, video footage and other compatible camera files.
• 128GB offers considerably more working space than smaller professional memory cards, making it useful for extended shooting sessions.
• The capacity is particularly useful for:
  • Professional photography
  • Burst shooting
  • RAW photography
  • 4K video
  • Long-form video recording
  • Weddings and events
  • Sports photography
  • Travel and documentary work
  • Commercial productions
• SanDisk notes that advertised storage capacities are based on 1GB = 1,000,000,000 bytes, so the actual usable storage displayed by a camera or computer will be lower.

Extremely Fast Read Speeds

• The SanDisk Extreme PRO CFexpress Type B 128GB offers sequential read speeds of up to 1700MB/s.
• High read performance is particularly valuable when transferring large quantities of photographs and video footage from the card to a computer.
• Faster read speeds can significantly reduce the time spent copying large media files after a shoot.
• This is particularly useful when working with:
  • Large RAW photographs
  • High-resolution JPEG collections
  • 4K video
  • Large batches of footage
  • Professional production files
• Actual transfer performance depends on the card reader, computer, connection interface and other hardware involved.

Fast 1200MB/s Write Performance

• The 128GB version provides sequential write speeds of up to 1200MB/s.
• High write performance allows the card to receive large amounts of data rapidly from compatible cameras.
• This is especially important when a camera is generating large amounts of data during:
  • High-speed continuous shooting
  • RAW burst photography
  • High-bitrate video recording
  • 4K video capture
• Faster card performance can help reduce the likelihood of the memory card becoming the limiting factor during demanding recording operations.
• Actual write performance can vary depending on the host camera, recording format, usage conditions and other factors.

Designed for RAW 4K Video

• The Extreme PRO CFexpress Type B is designed to support RAW 4K video capture with sustainable, low-latency performance.
• CFexpress technology provides the high data throughput required by cameras capable of producing large video files and high-bitrate recording formats.
• This makes the card particularly appropriate for professional video cameras and mirrorless cameras that offer demanding recording modes.
• However, support for a particular 4K, RAW or high-bitrate mode ultimately depends on the camera manufacturer's specifications and firmware.
• SanDisk specifically notes that 4K video support can vary according to the host device, file attributes, usage conditions and other factors.

Ideal for High-Speed Photography

• The card's high write performance makes it well suited to cameras capable of rapid continuous shooting.
• Professional photographers can use it for demanding situations where large numbers of high-resolution photographs need to be written to the card quickly.
• Suitable applications include:
  • Sports photography
  • Wildlife photography
  • Action photography
  • Events
  • Wedding photography
  • Press photography
  • Fashion photography
  • Commercial photography
• With compatible camera hardware, high-performance CFexpress storage can help maintain the camera's ability to record bursts without the memory card becoming an unnecessary bottleneck.

CFexpress Type B Format

• The card uses the CFexpress Type B form factor.
• CFexpress Type B is a professional memory-card format designed around high-speed PCIe-based data transfer.
• It is physically larger than CFexpress Type A and is commonly found in professional and high-performance mirrorless cameras and cinema cameras.
• CFexpress Type B is used by a wide range of professional camera manufacturers and is particularly common in systems from brands such as Nikon, Canon, Panasonic, Sony and other manufacturers, depending on the individual camera model.
• Compatibility must always be checked against the specific camera because not every camera supports CFexpress Type B.

Backwards Compatibility with Select XQD Cameras

• One of the notable features of this CFexpress Type B card is its backwards compatibility with select XQD host devices.
• Certain XQD cameras can use CFexpress Type B cards after receiving a manufacturer-provided firmware update that enables CFexpress compatibility.
• This provides a potential upgrade path for photographers who already own compatible XQD equipment.
• Compatibility is not universal across XQD cameras and depends on whether the camera manufacturer provides the necessary firmware support.

Low-Latency Performance

• CFexpress technology provides high-speed data communication between the card and compatible camera.
• SanDisk describes the Extreme PRO CFexpress Type B as providing low-latency performance for high-speed recording.
• This is particularly beneficial when the camera is continuously generating large quantities of data.
• For professional photographers and filmmakers, maintaining rapid data flow can be important when working with demanding recording modes.

Built for Professional Workflows

• The Extreme PRO CFexpress Type B is designed for users who require dependable high-speed storage rather than basic everyday memory.
• Its combination of 128GB capacity, up to 1700MB/s read performance and up to 1200MB/s write performance makes it appropriate for demanding camera workflows.
• It is particularly well suited to photographers and filmmakers who routinely work with large files and high-resolution recording formats.
• The card can be used both in-camera and with compatible CFexpress card readers for transferring footage to a computer.

Fast Offloading After a Shoot

• High read speeds can be particularly valuable once a shoot is complete.
• Instead of waiting for large quantities of footage to transfer at conventional memory-card speeds, compatible CFexpress readers can take advantage of the card's high transfer capability.
• This can improve the efficiency of professional workflows where multiple cards may need to be backed up between shooting sessions.
• For photographers working with hundreds or thousands of RAW images, the time saved during offloading can become particularly valuable.

Compact Professional Format

• Despite its high performance, the card remains extremely compact.
• The card measures 38.58 × 29.72 × 3.89mm.
• It weighs just 12.25g.
• Its compact size allows it to fit easily into camera cases, memory-card wallets and professional production bags.
• The small form factor also makes it practical to carry several cards as part of a backup or multi-camera workflow.

RescuePRO Deluxe Data Recovery Software

• The card includes an offer for RescuePRO® Deluxe data recovery software.
• The software can assist with recovering files that have been accidentally deleted from compatible memory cards.
• Registration is required to access the software offer and the applicable terms and conditions apply.
• Data recovery software should be regarded as an additional precaution rather than a substitute for maintaining proper backups of important photographs and video footage.

Suitable for Modern Mirrorless and Cinema Cameras

• CFexpress Type B is used by a range of high-performance cameras designed for professional photography and video.
• The card is particularly suitable for cameras that offer:
  • High-speed continuous shooting
  • High-resolution RAW photography
  • RAW video
  • High-bitrate 4K recording
  • Professional video codecs
  • Large burst buffers
• Before purchasing, users should check their specific camera's memory-card requirements and supported recording modes.

Important Performance Consideration

• The advertised 1700MB/s read and 1200MB/s write speeds are maximum sequential performance figures, rather than guaranteed speeds in every camera or reader.
• Actual performance can be lower depending on:
  • Camera hardware
  • Card reader
  • Computer hardware
  • Connection interface
  • Recording format
  • File sizes
  • Usage conditions
  • Firmware
• A camera must also be capable of taking advantage of CFexpress performance for the card's higher speeds to provide a practical benefit.
