An external SSD helps you export photos and videos or record supported ProRes footage. It does not expand your iPhone’s built-in storage, move apps or clear space automatically.
This guide covers iPhone 15 Pro and 15 Pro Max, with photo-export steps from Apple’s iOS 18 guide. Wording may vary by version; other iPhones, especially Lightning models, need a separate compatibility check.
Will an SSD help?
Check Settings → General → iPhone Storage first. If apps, messages or system storage are the problem, exporting photos may help very little. Review Apple’s storage recommendations before buying.
- Export photos and videos: copy selected files to a drive for archiving or transfer. Copying alone does not free the space used by the originals.
- Record new 4K60 ProRes video: use a compatible drive and cable to record directly from iPhone 15 Pro or Pro Max. The requirements below all apply.
- Keep a smaller photo library on the phone: if you already use iCloud Photos, Optimize Storage can keep smaller local versions and originals in iCloud, subject to your setup and cloud capacity. SSD copies need manual management.
When to consider the Samsung T7 Shield
The Samsung Portable SSD T7 Shield 1TB in Black, US model MU-PE1T0S/AM, is worth considering for repeated exports or a planned 4K60 ProRes setup. It has USB 3.2 Gen 2 and an included USB-C-to-C cable. Keep an existing drive if it meets your needs; choose capacity based on your actual files and recordings.
Samsung reports that the T7 Shield family meets the power and sustained-write requirements at 25°C room temperature, and that its internal evaluation confirmed iPhone 15 Pro/Pro Max 4K60 ProRes capture. These are conditional manufacturer results, not MOREGOSU hands-on tests or a guarantee for every setup or temperature. Samsung recommends its included genuine USB-C cable; all Apple requirements below still apply.
Skip this purchase if you want an automatic storage fix, cannot verify your copies or cannot test the complete recording setup before relying on it.

Check the connection and format
For ordinary file access, Apple requires one data partition and APFS, encrypted APFS, HFS+, exFAT, FAT32 or FAT format. Look for the drive in Files → Browse → Locations. Check the exact drive’s power needs and included data cable; a matching USB-C plug alone is insufficient. Apple lists a powered USB hub as an option when an external hard drive needs power on a USB-C iPhone.
Before changing a drive’s format, back up and verify its contents elsewhere: formatting erases data. If it does not appear in Files, check the connection and specifications before considering formatting.
Try a small export first
- Connect a compatible drive and confirm it appears in Files.
- In Photos, select a small, recognizable group of photos and videos. Choose Share → Export Unmodified Original, then the external drive under Locations, and save.
- Open the exported copies, check the expected items are present and play the videos. Keep the phone originals and, for important material, another independently verified copy.
Export Unmodified Original saves originals without the edited appearance of cropped or adjusted photos. In iOS 18.4 or later, a locked Hidden album can leave items out. A successful small export does not verify the whole library.
With an optimized iCloud Photos library, plan access to full-resolution originals first. Apple’s phone archive route uses Download and Keep Originals before export. If the phone is too full for that, use Apple’s computer-based archive instructions; do not assume an SSD bypasses that step.
Do not delete photos during this trial. With iCloud Photos, library deletions also remove those photos and videos from iCloud and other devices using the library. Verify separate exports before any later storage-cleanup decision.
Check every requirement for 4K60 ProRes
Apple requires all of the following together:
- exFAT format and no password-encrypted drive
- A USB 3 cable supporting at least 10 Gb/s
- At least 220 MB/s write speed and a maximum 4.5 W power draw
- At least 10% of the iPhone’s internal storage free
Advertised read speed does not prove write performance or power compatibility. The iPhone’s supplied charge cable supports USB 2 speeds; check the SSD’s actual included cable before buying another.
Before an important recording, make and play back a representative test clip with your intended settings. Appearing in Files is not a recording test. These checks cover this iPhone 15 Pro 4K60 example, not 4K120 or every video mode.
