128GB microSDXC Card for Action Cameras

The SanDisk Extreme Pro microSDXC card provides 128GB of storage for devices that accept the microSDXC form factor. It ships with a full-size SD adapter so the same card works in cameras, drones or laptops with standard SD slots. The card is new and was first listed by the manufacturer in 2022. It targets users who need removable media for high-resolution photos and video.

U3 A2 V30 Speed Rating for 4K Capture

The card carries UHS Speed Class 3, Video Speed Class 30 and Application Performance Class 2 ratings. These markings guarantee a minimum sustained write speed of 30MB/s and the ability to handle random read and write IOPS required by apps running directly from the card. If your device demands one of these classes for 4K recording or app storage, this card meets the requirement.

Simple Insert-and-Use Installation

Installation consists of placing the microSD card into the device slot or into the supplied SD adapter before inserting it into a full-size slot. No drivers or software are required. The most common issue is using the card in a host that does not support the microSDXC capacity standard or the UHS-I bus, which prevents the card from being recognised or limits its speed.
