Best SD Card for DJI Osmo Action 4

Expert recommendations based on DJI Osmo Action 4 specifications

Recommended Spec

microSD UHS-I (V30 or faster)

Using a V30 microSD UHS-I card ensures crisp 4K recording in smooth motion, so you won't miss a single thrilling moment. This means fewer worries about dropped frames, letting you focus on the experience. With this reliable card, your Osmo Action 4's incredible features shine in high-quality video and photos every time.

Official DJI Osmo Action 4 SD Card Requirements

  • Format: microSD UHS-I
  • Minimum Speed: V30 (30 MB/s write)
  • Maximum Capacity: Up to 2TB
Why these requirements? DJI officially requires a UHS-I microSD card with Speed Grade 3 (U3) and Video Speed Class 30 (V30) minimum for the Osmo Action 4, with a maximum supported capacity of 2TB. The Action 4 records 4K at 120fps with exceptional low-light performance from its large 1/1.3-inch sensor, which produces higher bitrates than typical action cameras — making the V30 minimum a firm requirement, not a suggestion.
