Product Description
1. PCIe Gen3x1 & NVMe-Powered Performance
Engineered with SD Express 7.0 technology, this card delivers up to 820MB/s read and 710MB/s write speeds, enabling seamless capture of 8K/4K RAW video and burst photography. Its V30 certification ensures minimum 30MB/s sustained writes, eliminating dropped frames during high-bitrate recording (e.g., 4K 60fps or 8K 30fps).
2. Industrial-Grade Durability & Capacity
With 256GB storage, it holds ~12 hours of 4K video (100Mbps) or 100,000+ high-res photos, ideal for creators needing extended recording without frequent swaps. Built to withstand -25°C to 85°C temperatures, shocks, and vibrations, it features waterproof, shockproof, and X-ray proof design, plus ECC error correction for data integrity in extreme environments.
Why Choose 256GB?
· Balanced Capacity for High-Resolution Workflows:
Stores full-day shoots or multiple projects while keeping costs manageable. Faster than UHS-II cards by 2.7x, it reduces post-production transfer times.
Compatible Products:
· Professional Cameras:
Designed for Sony A7S III, Canon EOS R5, and Panasonic Lumix GH6, supporting RAW video capture and high-speed still photography.
· Action Cameras & Drones:
Optimized for GoPro Hero 12, DJI Mavic 4, and Insta360 X4, enabling 8K aerial footage and 4K 120fps sports recording.
· Gaming Consoles & Laptops:
Works with Steam Deck and laptops featuring SD Express 7.0 slots for fast game loading and media storage.
· Industrial Devices:
Reliable for edge computing systems, 360° cameras, and surveillance equipment requiring high-throughput, durable storage.
