256GB Extreme PRO® microSDXC™ UHS-I Card

Overview

SanDisk Extreme PRO microSDXC UHS-I Card 256GB: High-Capacity, High-Speed Storage for Drone Data Capture

The SanDisk Extreme PRO microSDXC UHS-I Card delivers the speed and capacity professional drone operators need for extended data capture sessions in the field. With sequential read speeds up to 200MB/s and write speeds up to 140MB/s, this 256GB card handles sustained data throughput from high-resolution photo capture, 4K UHD video, and continuous mapping or inspection payloads without bottlenecking the mission. The added capacity over smaller cards means fewer card swaps during long flight sessions and more room for high-volume datasets.

Rated UHS Speed Class 3 (U3) and Video Speed Class 30 (V30), the card supports uninterrupted 4K UHD recording without dropped frames, a requirement for thermal inspection footage, infrastructure documentation, and mission-critical recordings where complete data capture matters as much as flight performance.

Shockproof, waterproof, temperature-proof, and X-ray-proof construction, combined with an operating range of -25°C to 85°C, means the card holds up to the handling and environmental exposure typical of active field deployment. Every card is backed by a Lifetime Limited Warranty from SanDisk.
