Can I Use External Storage with iPhone?

By Jack Smith — Updated March 8, 2026

iPhone 15+ (USB-C): Direct Connection

Starting with iPhone 15, Apple switched to USB-C. This means you can plug any USB-C flash drive or portable SSD directly into your iPhone with no adapter needed. iPhone 15 Pro and Pro Max support USB 3 speeds (up to 10 Gbps), making transfers very fast for large video files. iPhone 15 (standard) supports USB 2 speeds via USB-C (slower but still functional). Popular drives for iPhone 15+: Samsung T7 SSD, SanDisk Extreme SSD, LaCie Rugged SSD. Access files via the Files app. To import photos from a card reader, use a USB-C SD card reader and open the Photos app — iOS will offer to import directly.

iPhone 14 and Earlier (Lightning): Adapter Needed

Lightning iPhones need Apple's Lightning to USB 3 Camera Adapter ($39) to connect standard USB drives. This adapter provides a USB-A port and a Lightning power passthrough. The drive must be formatted as FAT32, exFAT, or APFS. Alternatively, some manufacturers make MFi-certified drives with built-in Lightning connectors on one end and USB-A or USB-C on the other — brands like Sandisk iXpand offer this. These plug directly into Lightning without an adapter and are powered by the phone.

How to Transfer Photos to an External Drive

1. Connect the drive (directly or via adapter).
2. Open the Files app and tap your external drive under Locations.
3. Tap the three dots in the top right and choose Import.
4. Navigate to your photos (or browse Photos directly) and select what to import.
5. Alternatively, open Photos, select photos, tap Share, tap Save to Files, then choose your external drive as the destination.
