How to choose

1

Choose USB4 drives like the Corsair EX400U if you transfer large video files, as they offer nearly triple the speed of USB 3.2 drives. For photo backups, USB 3.2 drives like the Lexar SL500 with 2,000 MB/s read speeds are sufficient.

2
Attachment Method

Select drives with MagSafe compatibility (Corsair EX400U, SanDisk Creator Phone SSD) for cable-free attachment. If you prefer a traditional connection, standard USB drives like the Samsung T9 are adequate.

3
Price Per Capacity

The SanDisk Creator Phone SSD offers the best value at approximately $150 for 1 TB. The Corsair EX400U costs $499 for the same capacity but justifies the premium with USB4 speeds and MagSafe integration.

4
Physical Size

For pocketable storage, choose the Crucial X10 Pro at 65×50×10mm. The Samsung T9 is larger at 88×60×14mm, while the SanDisk Creator Phone SSD is noted for a bulky form factor.

Our verdict

The Corsair EX400U is the top pick for its USB4 speed and MagSafe integration, despite its higher price. For budget-focused users, the Lexar SL500 offers strong performance and iOS compatibility at half the cost.
