Overview

The SanDisk 128GB Extreme PRO UHS-II SDXC card is engineered for photographers and videographers who need fast, dependable media for high-resolution capture. With read and write speeds reaching up to 300MB/s and a V90 video speed class rating, the card handles sustained recording of 8K and 4K UHD video without dropped frames or buffer bottlenecks. The UHS-II interface leverages a second row of pins for dramatically higher bus speeds compared to standard UHS-I cards, making it ideal for burst shooting in RAW and continuous high-bitrate video recording.

Beyond raw performance, the Extreme PRO UHS-II is built for demanding environments. Its IP68 rating means it can withstand submersion in water and exposure to dust, while drop testing up to 6 meters gives confidence when shooting in the field. SanDisk also includes a two-year subscription to RescuePRO Deluxe data recovery software, providing a safety net for recovering accidentally deleted or corrupted files. For professionals whose livelihoods depend on every frame, this card delivers the speed, capacity, and resilience to keep pace with modern camera systems.
