SanDisk Micro SDXC USH-I 64GB Class 10 Memory Card
The SanDisk Micro SDXC USH-I 64GB Class 10 Memory Card is a high-capacity, high-speed microSD card engineered for demanding mobile and embedded applications requiring sustained data transfer rates and reliable performance. Professional photographers, videographers, drone operators, and embedded systems engineers rely on this card for 4K video recording, RAW image capture, and continuous data logging in field conditions. This card solves the critical problem of storage bottlenecks in action cameras, smartphones, and IoT devices by delivering UHS-I bus interface speeds up to 104 MB/s with Class 10 write performance guarantees.
Product Overview
The SanDisk Micro SDXC USH-I operates on the UHS-I (Ultra High Speed) bus interface standard, which provides a dedicated data pathway separate from the legacy SD bus, enabling sustained read and write speeds that far exceed standard microSD cards. The card implements advanced flash memory architecture with error correction code (ECC) technology and wear-leveling algorithms to ensure data integrity across millions of write cycles. The Class 10 rating guarantees a minimum sustained write speed of 10 MB/s, critical for uninterrupted video recording at high bitrates and continuous sensor data acquisition in embedded systems.
This 64GB capacity model balances storage density with cost-effectiveness, making it ideal for professional applications where multiple cards are deployed across devices. The card features SanDisk's proprietary temperature management and shock-resistant design, with an operating temperature range of 0 to 60 degrees Celsius and resistance to water, X-rays, and magnetic fields. The compact form factor (11mm x 15mm x 1mm) ensures compatibility with virtually all microSD-compatible devices including smartphones, tablets, action cameras, drones, dashcams, and microcontroller-based systems.

How to Use
To use the SanDisk Micro SDXC USH-I 64GB card, first identify the microSD card slot on your device, typically located on the side panel of smartphones, in the battery compartment of cameras, or on expansion headers of embedded systems. Insert the card with the gold contact pins facing downward and the label facing toward you, pushing gently until you hear a click indicating secure seating. For devices without native microSD support, use a microSD to SD adapter (included with many SanDisk cards) to interface with full-size SD card readers on computers and professional equipment.
Before first use, especially in embedded systems or cameras, format the card using the device's native formatting utility to ensure optimal file system compatibility and performance. For smartphones and tablets, the card will be automatically recognized and can be configured as expandable storage or dedicated media storage depending on your device's Android version. When transferring large files or recording video, ensure your device supports UHS-I mode to achieve maximum speed benefits; older devices may operate in legacy modes with reduced performance. Always safely eject the card through your device's settings menu before physical removal to prevent data corruption. For long-term archival, store the card in a cool, dry environment away from magnetic fields and extreme temperatures.
Frequently Asked Questions
What is the difference between Class 10 and UHS-I speed ratings?
Class 10 is a minimum sustained write speed specification guaranteeing at least 10 MB/s write performance, crucial for video recording without frame drops. UHS-I is the bus interface standard enabling much higher theoretical maximum speeds up to 104 MB/s. A card can be both Class 10 and UHS-I compliant; the Class rating ensures baseline write performance while UHS-I enables faster peak speeds for read operations and burst transfers. This card meets both standards, providing reliable sustained writes and fast file transfers.
Can I use this card in older devices that don't support UHS-I?
Yes, the SanDisk Micro SDXC USH-I card is backward compatible with devices that only support legacy microSD interfaces. However, older devices will operate the card in standard mode at reduced speeds, typically 25 MB/s maximum. The card will function reliably but won't deliver the full 170 MB/s read or 90 MB/s write speeds. For devices like older smartphones or basic cameras, this backward compatibility ensures the card works without issues, though you won't benefit from the UHS-I speed advantages.
Is 64GB sufficient for 4K video recording?
For 4K UHD video at standard bitrates (50-100 Mbps), 64GB provides approximately 5-13 hours of continuous recording depending on codec and resolution. For professional cinema 4K at higher bitrates (200+ Mbps), capacity decreases to 2-3 hours. Most users should carry multiple cards for extended shoots. For embedded systems logging sensor data, 64GB typically provides weeks of continuous operation. Assess your specific bitrate requirements and recording duration to determine if additional cards are needed for your application.
What is the warranty coverage for this card?
The SanDisk Micro SDXC USH-I 64GB card comes with a 7-day warranty covering manufacturing defects only. This includes defects in materials, workmanship, and initial failure. The warranty does not cover physical damage, water damage from misuse, exposure to extreme conditions beyond specifications, or data loss.
