Overview

The SanDisk Extreme PRO SDXC UHS-II 128GB card is engineered for professionals who cannot afford dropped frames or missed shots. With read speeds reaching up to 300MB/s and write speeds up to 260MB/s, it ranks among the fastest SD cards available, making it a strong choice for photographers working in continuous burst mode and videographers capturing high-bitrate 8K or 4K footage. The V90 video speed class guarantees a minimum sustained write speed of 90MB/s, ensuring smooth, uninterrupted recording even at the highest resolutions.

Beyond raw speed, the card is built to survive demanding conditions. Its shockproof, waterproof, temperature-proof, and X-ray-proof construction means it can travel from studio to remote location without worry. The 128GB capacity strikes a practical balance between storage space and cost, offering enough room for extended shooting sessions while keeping the per-card investment reasonable. For post-production, pairing this card with a compatible UHS-II reader unlocks the full 300MB/s transfer rate, dramatically cutting the time spent moving large files to your editing workstation.
