Next-Generation CFexpress 4.0 Performance

Built on the latest CFexpress 4.0 specification, the ProGrade Digital CFexpress 4.0 Type B Gold Memory Card delivers a significant leap in storage performance compared to previous-generation media. Utilizing the high-bandwidth PCIe Gen4 x2 interface and NVMe 1.4c protocol, it is engineered to meet the growing demands of modern mirrorless cameras and cinema systems. This next-generation architecture enables photographers and filmmakers to capture larger files, record higher-resolution video, and transfer content more efficiently, making it a future-ready storage solution for professional workflows.

Blazing-Fast Read Speeds for Faster File Transfers

With maximum sequential read speeds of up to 3,400 MB/s, this memory card dramatically reduces the time required to transfer large RAW image collections and high-resolution video footage to your computer. Faster offloading means editors, photographers, and content creators can begin post-production sooner, shortening turnaround times and improving overall productivity. Whether you're handling thousands of photos after an event or terabytes of cinema footage, the card helps eliminate unnecessary workflow delays.

Exceptional Write Speeds for Demanding Professional Recording

Designed for professional content creation, the card delivers burst write speeds of up to 3,000 MB/s along with high sustained write performance depending on capacity. These speeds enable uninterrupted recording during demanding applications such as continuous RAW image bursts, high-frame-rate photography, and ultra-high-bitrate video recording. The consistent write performance helps minimize buffering and allows your camera to keep shooting when every moment matters.

Optimized Sustained Write Performance for Long Recording Sessions

Unlike cards that emphasize only peak performance, the ProGrade Digital CFexpress 4.0 Type B Gold Memory Card is engineered to maintain reliable sustained write speeds throughout extended recording sessions. Depending on the selected capacity, sustained write performance reaches up to 1,500 MB/s, making it well suited for long-form productions where maintaining consistent recording speed is critical. This stability is especially valuable during interviews, documentaries, live events, and cinematic productions where interruptions simply aren't an option.

Designed for Professional 4K, 6K, and 8K Video Production

Modern video production demands storage capable of handling extremely large data streams, and this card is built specifically for that challenge. It supports demanding workflows involving 4K, 6K, and 8K video recording, including professional codecs such as RAW and ProRes. The high sustained throughput allows videographers and filmmakers to record high-quality footage with confidence while reducing the risk of dropped frames or recording interruptions during critical productions.

Perfect for High-Speed RAW Photography

Professional photographers require storage that can keep pace with today's high-resolution image sensors and rapid continuous shooting modes. Whether capturing wildlife, sports, motorsports, weddings, or fast-moving action, the ProGrade Digital CFexpress 4.0 Type B Gold Memory Card provides the speed necessary to clear camera buffers quickly and sustain extended RAW burst shooting. This allows photographers to focus on timing and composition rather than waiting for storage performance to catch up.

Advanced PCIe Gen4 x2 and NVMe 1.4c Architecture

At the heart of the card is a cutting-edge combination of PCI Express Gen4 x2 technology and the NVMe 1.4c storage protocol. Together, these technologies deliver substantially higher bandwidth, lower latency, and more efficient communication between the camera and memory card. This advanced architecture enables faster data access, improved responsiveness, and better overall storage efficiency compared to older memory card technologies.

Backward Compatibility Protects Your Investment

While designed for the latest CFexpress 4.0 ecosystem, the card remains backward compatible with many devices that support CFexpress Type B 2.0. This allows professionals to upgrade their storage today while continuing to use existing compatible cameras and card readers. As future camera models adopt higher-performance interfaces, users can take advantage of the card's full capabilities without needing to replace their storage media again.

Professional-Grade Reliability for Mission-Critical Work

When every file is valuable, reliability becomes just as important as speed. The ProGrade Digital CFexpress 4.0 Type B Gold Memory Card incorporates professional-grade flash management technologies, including LDPC error correction, intelligent wear-leveling, bad block management, and thermal monitoring. These technologies work together to maintain long-term performance while protecting valuable photos and video footage throughout the life of the card.

Durable Metal Construction for Improved Heat Dissipation

The card features a robust metal enclosure that enhances durability while also serving as an efficient heat spreader. During demanding workloads such as extended 8K recording or continuous burst photography, effective heat management helps maintain stable operating temperatures and minimizes the likelihood of thermal throttling. The rugged construction also provides additional protection for professionals working in challenging environments.

Low Power Consumption for Longer Shooting Sessions

Despite its exceptional performance, the card is engineered with efficient power management to reduce energy consumption. Support for multiple NVMe power states, including ultra-low standby power, helps minimize battery drain during long photography and video sessions. This makes it particularly beneficial for location shoots where battery life is limited and uninterrupted operation is essential.

Built to Perform in Harsh Environmental Conditions

Professional creators often work in unpredictable environments, and this memory card is designed accordingly. It operates reliably across a wide temperature range and is resistant to shock, vibration, high humidity, and airport X-ray exposure. Whether shooting in freezing mountain conditions, hot desert landscapes, or fast-paced production sets, it provides dependable performance when conditions become demanding.
