This card's performance is maintained by a dynamic SLC cache, which helps maintain its sustained read/write performance. General Features Harness the Full Potential with CFexpress The Cinema EX utilizes CFexpress 2.0 technology to deliver fast performance for the most demanding professional photographers and videographers. Its read and write speeds are both more than 3 times faster than CFast 2.0 media, leveraging the maximum performance of high-end digital film cameras. Write Speeds That Reach Unparalleled Levels With its PCIe 3.0 x2 interface, as well as support for NVMe 1.3, the Cinema EX boasts extreme recording speeds up to 1200 MB/s for flawless cinema-quality video capture, including 8K at high frame rates and bitrates. It also supports raw continuous-burst shooting without delay, so you won't miss a frame during those critical split-second moments. Technology That Maximizes Performance The Cinema EX is more than just impressive speeds. To keep up with the pace that professionals demand, dynamic SLC Cache firmware works to provide optimal read/write sustained performance, while SmartRefresh technology works to maintain high read performance over time. Technology for Endurance and Stability A card's ability to keep data safe is just as important as its ability to record it. An LDPC ECC engine and Block/Page RAID function with 3D NAND guarantees 3K PE cycles for enhanced endurance. SmartFlush power-shielding firmware protects data during unstable conditions.
