Best SD Card for iPhone 14 Pro

Expert recommendations based on iPhone 14 Pro Max specifications

Recommended Spec

External via Lightning Reader (UHS-I or faster)

With external SD card access via Lightning reader, you can expand your iPhone 14 Pro Max storage seamlessly. This means you'll never have to worry about running out of space for your photos, videos, or files, giving you peace of mind to capture life's moments. Now you'll be able to store, transfer, and manage your media on the go.

Official iPhone 14 Pro SD Card Requirements

  • Format: External via Lightning Reader
  • Minimum Speed: UHS-I (undefined write)
  • Maximum Capacity: Up to undefined
Why these requirements? The iPhone 14 Pro Max shoots ProRes video at up to 4K/30fps, which can eat over 6GB per minute at the highest quality — but there's no way to record directly to an external SD card via a Lightning reader; ProRes at that bitrate needs an external SSD connected through a USB 3 adapter, not a microSD card. A Lightning microSD reader is still useful for the ordinary case of importing photos or footage from a camera's SD card into the Photos app, but treat it as an import/offload tool, not a recording destination, and prioritize buying enough internal storage (256GB+) if you shoot ProRes regularly.
