SanDisk's latest addition to its storage lineup, the Extreme PRO CFexpress 4.0 Type B cards, brings significant advancements in performance and capacity for professional video workflows. The new cards are designed to handle high-resolution formats, including up to 12K, with a focus on sustained high-bitrate recording scenarios.
The cards utilize a PCIe Gen 4 interface, delivering sequential read speeds of up to 3,700 MB/s and write speeds of up to 3,500 MB/s. Sustained write performance varies by capacity, with the 2 TB and 4 TB models rated at up to 3,100 MB/s. The 1 TB model offers sustained writes at 1,950 MB/s, while lower-capacity variants (128 GB to 400 GB) are rated for up to 900 MB/s.
Higher-capacity models (1 TB to 4 TB) support VPG1600 certification, ensuring they meet the demanding requirements of professional video production. Lower capacities are rated for VPG800 or VPG400, depending on the SKU. SanDisk has also incorporated its SmartIdle feature, which reduces thermal load during idle periods by lowering power consumption.
The cards are built to withstand field use, with resistance to drops of up to 5 meters and bend forces up to 70 N. They are aimed at sustained high-bitrate recording scenarios, including 4K, 6K, 8K, and higher formats.
Pricing starts at $249.99 for the 128 GB model and goes up to $1,799.99 for the 4 TB variant. All models are backed by a limited lifetime warranty.
This expansion of SanDisk's storage portfolio is a strategic move that addresses the growing demand for high-performance, durable storage solutions in professional video workflows. The introduction of these cards underscores the importance of efficient and reliable storage in handling increasingly complex and high-resolution video formats.
