The Delkin Devices DCFXBP165G4 is a high-performance 165GB CFexpress Type B memory card engineered for the most demanding professional photography and videography applications. Part of Delkin's POWER series, this card is designed to meet the extreme data rate requirements of high-resolution mirrorless cameras, cinema cameras, and digital recorders that utilize the CFexpress Type B standard. It leverages the PCIe Gen 3 x2 interface and NVMe protocol to deliver exceptional sustained read and write speeds, which are essential for capturing high-bitrate RAW video formats, high-frame-rate slow-motion, and continuous high-resolution burst photography without buffer limitations. The card's robust construction and advanced thermal management ensure consistent performance even during long, uninterrupted recording sessions, preventing slowdowns due to overheating.

Built to withstand the rigors of professional use in challenging environments, the card is temperature-proof, shockproof, vibration-proof, and X-ray proof. It is rated for operation across a wide temperature range, from well below freezing to high heat, making it reliable for assignments in extreme climates, from arctic expeditions to desert shoots. The card employs advanced flash memory management, wear-leveling algorithms, and error correction code (ECC) to safeguard data integrity and extend the card's operational lifespan, even under constant heavy read/write cycles. Delkin often includes proprietary data recovery software with the card, offering an additional layer of protection for invaluable footage and images in cases of accidental deletion or file corruption.

The card is formatted with the exFAT file system, supporting individual file sizes larger than 4GB, which is critical for long-duration, high-resolution video clips. Its high sustained write speeds ensure that cameras can maintain their maximum recording specifications without dropping frames. Backed by a limited lifetime warranty and Delkin's professional support, the POWER CFexpress Type B card provides a reliable, high-speed storage solution for cinematographers, photojournalists, and content creators who require maximum performance, capacity, and data security from their memory cards in critical shooting situations.
