For filmmakers using cinema cameras that incorporate CFexpress technology: - Achieve seamless 8K video capture with incredibly fast minimum sustained write speeds of 1400MB/s (8K (7680x4320) video support may depend on the host device, file attributes, usage conditions, and other factors. Visit the official SanDisk website for more details. Read speeds can reach up to 1700MB/s, and write speeds can go up to 1500MB/s. These figures are based on internal testing, with performance potentially lower depending on the host device, usage conditions, and other factors. 1MB = 1,000,000 bytes). - Enjoy extremely fast burst speeds, with write speeds up to 1500MB/s and read speeds up to 1700MB/s (minimum sustained write speed is 1400MB/s. Performance figures are based on internal testing, and actual speeds may vary depending on the host device, usage conditions, and other factors. 1MB = 1,000,000 bytes). - Designed to be durable, it can withstand drops from up to 1 meter and forces up to 50 newtons (11.2 pounds-force) (based on internal testing).
