7. Performance Notes
- Data Transfer Speed: Supports up to 312MB/s with high-performance SD & TF 4.0 ports. The 10Gbps USB-C connector is designed to match the iPhone's highest transmission capabilities.
- 4K 120fps ProRes Recording: The native iPhone camera's 4K 120fps ProRes recording mode requires an external card with a write speed of at least 440MB/s, which exceeds the SD 4.0 protocol's capabilities. For real-time 4K 120fps ProRes recording and storage, third-party applications like Blackmagic Camera are recommended.
Recommended Card Specifications for ProRes Recording:
| Video Format | Recommended Write Speed | Recommended Capacity |
|---|---|---|
| 4K60 ProRes | ≥ 220 MB/s | ≥ 256 GB |
| 4K30 ProRes / 4K24 ProRes | ≥ 150 MB/s | ≥ 128 GB |
| HD30 ProRes | ≥ 100 MB/s | ≥ 64 GB |
