Compatible With

• Cameras and devices with CFexpress Type B card slots

Next-Generation CFexpress 4.0 Performance

With maximum read speeds up to 3700 MB/s and maximum write speeds up to 3200 MB/s, this card is designed for elite-level capture and transfer tasks. These speeds are especially valuable when recording high-bitrate video, shooting long bursts of RAW stills, or moving large projects to a workstation. Fast media reduces camera buffer delays and dramatically improves ingest times, making it a practical upgrade for demanding professionals.

Optimized for Professional Video

The card is well suited to modern production environments where large codecs and high frame rates are increasingly common. Whether you are capturing detailed 4K, advanced 6K, or even 8K workflows, the Extreme PRO CFexpress 4.0 Type B card offers the speed headroom needed for data-heavy recording formats. This makes it a strong choice for documentary work, interviews, events, commercial production, and hybrid creator setups that move between stills and video.

Excellent for High-Speed Still Photography

Sports, wildlife, action, photojournalism, and commercial shooters often rely on continuous high-speed burst capture to secure decisive moments. A fast CFexpress Type B card helps sustain longer bursts, clears the camera buffer more quickly, and supports smoother shooting under pressure. For photographers working with high-resolution sensors and large RAW files, the benefit is immediately noticeable in both capture responsiveness and card-to-computer transfer times.

Durable Design for Demanding Use

Professional memory cards need more than raw speed—they also need dependable construction. SanDisk's Extreme PRO line is designed with serious field use in mind, giving creators confidence when working on location, traveling between shoots, or operating in fast-paced production environments. This dependable build makes the card a practical tool for wedding photographers, filmmakers, content creators, and commercial teams who cannot afford unreliable media.

Workflow Benefits in Real-World Use

In daily production, storage speed affects more than spec sheets. Faster media can reduce downtime between takes, improve responsiveness during burst shooting, and shorten file transfers at the end of the day. If your camera supports the bandwidth of CFexpress Type B media, a card like this helps streamline capture-to-edit workflows. Editors and DITs also benefit from faster ingest when offloading footage and backing up media in the field or studio.

How It Compares

Compared with older CompactFlash, SD, or XQD media, CFexpress Type B cards offer dramatically improved throughput for modern cameras with intensive data requirements. Compared with lower-tier CFexpress cards, the Extreme PRO 4.0 series is aimed at users who prioritize premium transfer speed and top-tier capture performance. The 128GB capacity is especially useful for shooters who prefer rotating multiple cards for organization, redundancy planning, or project separation rather than relying on a single larger-capacity card.

Recommended Accessories

To get the most from this card, pair it with a high-speed CFexpress Type B card reader that supports modern USB or equivalent high-bandwidth interfaces. Additional recommended accessories include a rugged media case for transport, a multi-card wallet for location work, backup storage drives for immediate offload, and a labeling system for organized production workflow. A fast reader is especially important if you want to take full advantage of the card's transfer capabilities.

Usage Tips

For best results, format the card in-camera before important shoots, confirm your camera firmware supports CFexpress Type B media, and use a reader capable of high-speed transfer for offloading. If recording mission-critical content, rotate cards methodically and back up files as soon as possible. Keeping card contacts clean and storing media in a protective case can also help maintain consistent long-term performance.
