Product Overview

The SanDisk Extreme microSD UHS-I Card is a high-speed, rugged storage solution built for action cameras, drones, smartphones, and portable recorders.

The 32GB version delivers up to 100MB/s read and 60MB/s write, rated A1. All capacities feature a five-proof durable design: waterproof, temperature-proof (-25°C to 85°C), shock-proof, X-ray-proof, and magnet-proof. Ideal for outdoor shooting, travel, and extreme environments. Includes a free card reader and SD adapter for cross-device compatibility.

Key Features

• High-Speed 4K Recording: U3 / V30 / Class 10 — sustained write for uninterrupted 4K video; 64GB+ hits 160MB/s read, 90MB/s write; 32GB hits 100MB/s read, 60MB/s write.

• A2 App Performance (64GB+): A2 rating enables faster app launch and loading when apps are installed directly on the card — perfect for Android phone storage expansion.

• ️ Five-Protection Durability: Waterproof, shock-proof, temperature-proof (-25°C ~ 85°C operating), X-ray-proof (safe for airport security), magnet-proof — survives harsh outdoor and travel conditions.

• Versatile Compatibility: Works with action cams, drones, dash cams, surveillance, Android phones, handheld gaming consoles, and more.

• Free Bundle: Includes USB card reader for direct PC connection and SD adapter for DSLR/camera use — no extra accessories needed.

️ Technical Specifications

Usage Tips

• Format before first use: Always format the card in the host device (camera, drone, phone) before first use to ensure optimal file system compatibility.

• Choose 64GB+ for 4K: For sustained 4K recording, select 64GB or higher to benefit from faster write speeds (90MB/s) and A2 rating.

• Use included reader: The free USB card reader enables direct file transfer to PC — no need for a separate card reader.

• SD adapter for DSLR: Use the included SD adapter to read the card in DSLR cameras or laptop SD slots.

• Avoid full capacity: Leave ~10% free space to maintain write performance and reduce file corruption risk during continuous recording.

️ Important Notes

• Capacity variance: Storage manufacturers calculate 1GB = 1000MB; device OS may show slightly less — this is normal and not a defect.

• 4K requires 64GB+: For reliable 4K recording, choose 64GB or above; 32GB is suitable for 1080p but may struggle with high-bitrate 4K.

• Format in-device: First-time use requires formatting in the target device to avoid file system errors.

• Temperature limits: Operating -25°C ~ 85°C; avoid exceeding these ranges to prevent data corruption or card damage.

• Not for internal SSD use: This is a microSD card, not an SSD; do not use as primary OS drive in laptops.
