SanDisk Extreme PRO microSDXC UHS-I Card 256GB: High-Capacity Storage Built for Enterprise Fleet Data Demands

The SanDisk Extreme PRO microSDXC UHS-I Card scales to meet the data demands of enterprise drone programs running longer missions and higher-resolution payloads. With sequential read speeds up to 200MB/s and write speeds up to 140MB/s, the 256GB card sustains the continuous data throughput that mapping, LiDAR, multispectral, and extended inspection flights generate.

For fleet operators managing data capture across multiple aircraft and recurring mission cycles, the added capacity reduces mid-mission card swaps while the elevated write speed keeps pace with demanding video and high-resolution capture workloads.

Rated U3 and V30 for video performance, the card supports uninterrupted 4K UHD recording without dropped frames — a baseline requirement for thermal inspection, infrastructure documentation, and time-sensitive public safety footage where incomplete data undermines mission value.

Built shockproof, waterproof, temperature-proof, and X-ray-proof, and rated to operate from -25°C to 85°C, the card is engineered for the handling, transport, and environmental variation that enterprise field deployments routinely involve. Every card carries a Lifetime Limited Warranty from SanDisk.

Mission-Ready Capabilities

  • Sustained throughput: read speeds up to 200MB/s support fast post-mission data offload.
  • Elevated write performance: up to 140MB/s write speed handles demanding continuous recording.
  • Video-grade rating: U3 and V30 classifications ensure dropped-frame-free 4K UHD capture.
  • Offload efficiency: QuickFlow technology reduces time between landing and data processing.
  • Field durability: shockproof, waterproof, and temperature-proof construction withstands deployment conditions.
  • Travel security: X-ray-proof design protects stored mission data through transport and screening.
  • Operating range: rated from -25°C to 85°C for consistent performance across climates.
  • Extended capacity: 256GB reduces card-swap frequency during long-duration missions.
  • Manufacturer-backed: Lifetime Limited Warranty provides long-term assurance for mission-critical storage.

For programs running structured data capture across mapping, inspection, and survey workflows, storage write speed and capacity directly affect mission throughput. A card that cannot sustain continuous high-bitrate recording risks dropped frames on exactly the footage that matters most; a card with insufficient capacity forces a mid-mission swap that interrupts data continuity and field schedule. The 256GB Extreme PRO card addresses both variables, with write speed headroom and capacity scaled for serious payload data capture.

Dronefly stocks the SanDisk Extreme PRO microSDXC UHS-I Card as part of a complete accessories portfolio supporting enterprise drone operations. For fleet managers standardizing storage media across a multi-aircraft program, the 256GB capacity offers a practical balance of performance and storage headroom for higher-volume data capture requirements.

How does the 256GB capacity benefit enterprise programs running extended or multi-payload missions?

The 256GB capacity reduces the frequency of mid-mission card swaps, which matters for programs running long-duration mapping flights, multi-payload data capture, or back-to-back sorties without ground time to swap storage media. Combined with write speeds up to 140MB/s, the card sustains continuous high-resolution photo and 4K video capture without the throughput bottleneck that can affect smaller-capacity or slower-rated cards during demanding payload operations.

Why is the 256GB card rated for higher write speeds than the 128GB version?

SanDisk's Extreme PRO microSD lineup scales write speed by capacity tier. The 64GB and 128GB cards are rated up to 90MB/s write, while 256GB and larger capacities reach up to 140MB/s write. This is a confirmed manufacturer specification, and for fleet operators choosing between capacities, it means the 256GB card delivers a meaningful write performance advantage in addition to its storage headroom, which is relevant for write-intensive payloads like continuous video or high-frame-rate photo capture.

Is this card a good fit for standardizing storage across a fleet with mixed mission profiles?

Yes. The 256GB Extreme PRO card offers a practical middle ground for fleet operators running a mix of standard inspection flights and longer or higher-resolution data capture missions. Standardizing on a single verified, higher-capacity card across the fleet simplifies field logistics, reduces the variability of mixed storage media quality, and provides headroom for missions with heavier data requirements without needing a separate higher-capacity SKU for select operations.

How does the card perform across the environmental range enterprise field deployments encounter?

The card is shockproof, waterproof, temperature-proof, and X-ray-proof, and rated to operate from -25°C to 85°C. These specifications support deployment across varied climates and field conditions, from cold-weather infrastructure inspection to high-heat industrial sites, and the X-ray-proof rating protects stored data during airport security screening as equipment travels between job sites or deployment locations.

What does QuickFlow Technology mean for data processing turnaround?

QuickFlow Technology optimizes the card's read performance for faster offload after a mission. For programs with high flight volume or tight data delivery timelines, faster transfer speed from card to workstation reduces the gap between mission completion and the start of data processing, supporting faster client deliverable turnaround on inspection reports, mapping outputs, or survey datasets.
