20 April 2026 at 18:32
Sandisk introduced new Extreme PRO CFexpress 4.0 Type B memory cards, expanding its high-end storage lineup with capacities ranging from 128 GB up to 4 TB. The new cards target professional video workflows, including high-resolution formats up to 12K. Using a PCIe Gen 4 interface the cards can deliver sequential read speeds of up to 3,700 MB/s and write speeds of up to 3,500 MB/s across the lineup. 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 at 1,950 MB/s, and lower-capacity variants (128 GB to 400 GB) at up to 900 MB/s. Higher-capacity models (1 TB to 4 TB) support VPG1600 certification, while lower capacities are rated for VPG800 or VPG400, depending on the SKU.
Sandisk also added its SmartIdle feature to reduce thermal load during idle periods by lowering power consumption. The cards are built for field use, with resistance to drops of up to 5 meters and bend forces up to 70 N. As expected for this class of storage, they are aimed at sustained high-bitrate recording scenarios, including 4K, 6K, 8K, and higher. 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.
