Founded in Japan by former Sony engineers with over 20 years of memory expertise, the Nextorage B3SE Series CFexpress Type B memory card provides a highly reliable storage solution for professional photographers and filmmakers. Utilizing high-quality TLC NAND flash and the CFexpress 4.0 standard, it delivers maximum read speeds of up to 3,900 MB/s and write speeds of up to 2,000 MB/s. This performance minimizes buffer times during continuous high-speed shooting and accelerates the transfer of massive RAW image and video files, drastically streamlining post-production workflows. It provides the robust performance needed for capturing fast-action stills and high-resolution video up to 8K 60fps. The card is fully compatible with a wide range of top-tier mirrorless and DSLR cameras*, and maintains full backward compatibility to operate seamlessly with existing CFexpress 2.0 host devices. It is also compatible with camera monitor-recorder such as Atomos NINJA TX,NINJA TX GO, and NINJA RAW. Engineered for demanding environments, the card has passed six strict durability tests, making it shockproof (EIA-364-27A), temperature-resistant (-12°C to 72°C), X-ray proof, UV-resistant, anti-magnetic, and electrostatic-resistant. Finally, the product includes free access to the downloadable "Memory Card File Rescue" software for data recovery. *Canon (EOS R3, EOS R5), Nikon (D5, D500, D850, Z9, Z6, Z6 II, Z6 III, Z7, Z7 II, Z8), Fujifilm (X-H2S,X-H2), Panasonic (LUMIX DC-GH6, S1).
