These cards deliver read speeds of up to 1900 MB/s, write speeds of up to 1700 MB/s, and minimum sustained write speeds that won't drop below 1600 MB/s, all of which allows you to capture smooth raw 8K, 6K, 4K, and beyond video.

Designed to leverage the capabilities of next-generation cinema cameras, mirrorless cameras, and DSLRs, these cards utilize the PCI Express 3.0 x2 and NVMe protocols to provide high-speed performance, durability, and reliability.
