This SANDISK Extreme PRO microSDXC card combines large capacity with high sequential read performance, reducing wait times when transferring photos, videos or large data sets. The V30 video speed class ensures reliable sustained recording for 4K video and burst photography, while the A2 app performance class improves application load and run times on supported Android devices. The card is compatible with UHS-I hosts and is suitable for devices that accept microSDXC format.

Suitable for

• 4K video recording in action cameras, drones and mirrorless cameras that accept microSDXC cards
• High-resolution photo capture and burst shooting
• Smartphones and tablets used for media storage and running apps with improved responsiveness
• Backup and transport of large media libraries and project files

When it may not be suitable

This card may not provide full benefit when used in devices limited to lower interface speeds than UHS-I or in legacy microSD/SDHC hosts that cannot address microSDXC capacity. It may also be unnecessary for simple tasks such as occasional document storage or devices that do not require high sustained write performance.

How to use

Insert the microSDXC card into the microSD slot of a compatible device following the device manufacturer’s guidelines and ensuring the card is correctly oriented. Format the card in the device before first use if prompted to ensure optimal compatibility. When transferring files to a computer, use a UHS-I compatible card reader or the device’s native transfer method to achieve faster transfer speeds. Remove the card only after the host device indicates it is safe to eject to avoid data corruption.

What to consider before purchase

• Ensure your device supports microSDXC cards and the UHS-I interface to utilize the card’s speed and capacity.
• Check whether sustained write performance (V30) and app performance (A2) are required for your intended use, such as 4K video or app storage.
• Confirm the physical compatibility and available slot type in cameras, drones or mobile devices.
• Be aware that actual transfer and write speeds depend on device capability and card reader performance.

Usage recommendations

For reliable 4K video capture and fast file handling, pair this microSDXC card with UHS-I compatible devices and use a high-quality UHS-I card reader for transfers. Regularly back up important files and format the card in the host device if you change devices to maintain optimal performance.
