Why Smaller SD Cards Aren’t Practical
Smaller SD cards, like 32GB or 64GB, quickly fill up with high-quality footage. For example:
- 32GB SD Card: About 30 minutes of 4K video at 30fps.
- 64GB SD Card: About 1 hour of 4K video at 30fps.
Frequent swaps can interrupt filming and lead to misplaced or unorganized footage. Avoid these sizes if you plan extended shoots or use high resolutions.

1TB SD Card – Overkill for Most Users
While 1TB cards provide ample storage, they come with drawbacks:
- High Risk of Data Loss: All your footage is stored on one card, making data recovery harder if the card fails.
- Long Transfer Times: Offloading such large amounts of data can be time-consuming.
- Cost: 1TB cards are expensive, and smaller cards like 256GB or 512GB offer better value and flexibility.
SD Card Speed Classes for Insta360 Cameras
The speed class determines how fast data is written to the card, which is critical for high-resolution video and fast-action scenes.
Choosing the right speed class is essential to:
- Prevent Dropped Frames: Avoid stuttering or missed frames during high-resolution recording.
- Speed Up Transfers: Faster cards save time when offloading footage to your computer.
- Ensure Consistent Performance: Keep your Insta360 camera operating at its best.
To verify your SD card’s speed, use tools like CrystalDiskMark (Windows) or Blackmagic Disk Speed Test (Mac). Find all the Free speed testing tools here>>>

V30 or U3 – Great for 4K
With a minimum write speed of 30MB/s, V30 and U3 cards are excellent for smooth 4K video at 30fps or 60fps. These cards are ideal for casual filming or light action shots.
V60 – Advanced for High-Frame-Rate 4K or 5.3K
V60 cards provide a minimum write speed of 60MB/s, making them suitable for 4K at 120fps or 5.3K footage. They’re ideal for capturing detailed, high-frame-rate scenes.
V90 – Essential for 8K or Professional Use
V90 cards offer a minimum write speed of 90MB/s and are built for demanding tasks like 8K recording or ultra-high-bitrate videos. These cards ensure smooth performance in even the most intensive shooting scenarios.
