Best External SSDs for Mac Photo Backup in 2026

If you're archiving your iCloud photo library to an external drive, choosing the right SSD matters. Here are the best options in 2026.

What to Look For

Before buying, consider:

Capacity — 1TB is enough for most users, 2TB if you have large video files

Speed — USB 3.2 or Thunderbolt for fast transfers

Reliability — SSDs are far more reliable than spinning hard drives

Compatibility — all these work plug-and-play with Mac

Samsung T7 Shield — Best Overall

The Samsung T7 Shield is rugged, fast and reliable. It offers USB 3.2 Gen 2 speeds up to 1,050MB/s and comes in a rubberised case that survives drops.

1TB — around $100

2TB — around $160

Works perfectly with Migrate Moments

SanDisk Extreme — Best Value

The SanDisk Extreme offers excellent performance at a slightly lower price point. Reliable brand with a long track record.

1TB — around $90

2TB — around $140

Samsung T9 — Best Performance

If you're transferring very large libraries with hundreds of GB of RAW photos or 4K video, the T9 offers the fastest USB speeds available.

1TB — around $130

2TB — around $200

WD My Passport SSD — Best for Beginners

Simple, compact and affordable. The WD My Passport is a solid choice if you want something straightforward without spending too much.

1TB — around $85

How Much Storage Do You Need?

Under 20,000 photos: 500GB is likely enough

20,000 to 50,000 photos: 1TB recommended

50,000+ photos or lots of video: 2TB

When in doubt, go bigger. Storage is cheap — running out mid-export is not.

Ready to Archive?

Once you have your SSD, download Migrate Moments to export your iCloud photo library automatically — organised by year and month, with nothing deleted until verified on your drive.
