The Lexar Professional CFexpress Type B Diamond Series 256GB memory card is a high-performance solid-state storage solution designed to meet the rigorous standards of professional video production and high-resolution photography. Through the integration of PCIe Gen 3x2 and NVMe protocols, this unit achieves sequential read speeds of up to 1900 MB/s and write speeds of up to 1700 MB/s, ensuring an efficient workflow when transferring large volumes of data. The VPG400 certification guarantees a minimum sustained write speed of 400 MB/s, a critical parameter for the uninterrupted recording of 8K RAW, ProRes, and high-frame-rate video streams without frame loss. The physical structure of the card is engineered to withstand mechanical stress, shock, and vibration, operating across an extended temperature range to ensure data integrity even in adverse environmental conditions. Backward compatibility with selected XQD cameras enhances the media's versatility, making it a reliable tool for digital acquisition systems that require the maximum bandwidth available on the Type B interface bus.
