Designed for Insta360 cameras

This 128GB microSDXC card is built for Insta360 X3, Sphere, ONE RS, ONE X2, ONE R and ONE X cameras. It delivers the sustained write speed those devices need for 4K capture. The UHS-I interface and V30 rating guarantee a minimum 30MB/s sequential write rate. Photographers and creators who use these specific models get reliable, drop-free recording.

Suits single-camera workflows

The card fits creators who shoot on one supported Insta360 body and want a single high-capacity card for a full day of 4K footage. It is not suited for multi-camera rigs that require several cards simultaneously. Users who need UHS-II bus speeds or higher video speed classes for other hardware should select a different card. The 128GB capacity also limits very long continuous sessions without offloading.

V30 sustained write guarantee

The V30 video speed class is the single specification that decides suitability. It certifies a minimum 30MB/s sustained write, which is the threshold for stable 4K recording on the listed Insta360 cameras. If your device demands a higher sustained write rating, this card will not meet that requirement.
