The Insta360 GO Ultra, announced on August 21, 2025 , is the new hands-free mini action cam that succeeds the GO 3S. With its 1/1.28” sensor (221% larger than that of the GO 3S), it now films in 4K at 60 frames per second , has a PureVideo mode for low light and includes removable storage via microSD card, up to 2 TB . This is an expected new feature, since the older models were satisfied with non-expandable internal memory.
But to unlock its full potential (including the maximum speed of 180 Mb/s ), it’s essential to choose a suitable memory card. Here’s our guide to the best microSD cards for the Insta360 GO Ultra .
Criteria to consider when choosing a microSD card
- Write and read speed : With high video bitrate, it is recommended to opt for a UHS-I U3 / V30 card minimum . This ensures smooth writing in 4K/60.

- Capacity : The Insta360 GO Ultra accepts up to 2TB , but a good compromise is often 256GB or 512GB , offering an excellent price/storage ratio.
