ProMaster CFexpress 4.0 Type B 512GB Advanced Memory Card
The ProMaster CFexpress 4.0 Type B 512GB Advanced Memory Card provides high-speed removable storage for compatible professional cameras and video systems. Its PCI Express 4.0 and NVMe interface supports maximum read speeds up to 3500 MB/s, maximum write speeds up to 3200 MB/s, and an 820 MB/s minimum sustained sequential write speed.
Built for photographers and filmmakers capturing high-resolution media, the 512GB Advanced card combines substantial capacity with sustained performance for demanding recording modes and rapid still-image sequences. The 820 MB/s sustained write specification is particularly useful when a camera must maintain continuous data transfer rather than relying only on short peak-speed bursts.
ProMaster uses quality flash memory and components designed for repeated read and write cycles. The card operates from 32°F to 158°F and carries a limited lifetime warranty. ProMaster recommends formatting the card in the intended camera before use to optimize performance and compatibility with the recording device.
