Can You Use a USB-C Flash Drive with an iPhone?
In short
Yes. iPhone 15 and later have a USB-C port and open external drives in the Files app, so a USB-C flash drive plugs straight in. You can copy photos and files off the phone to free up space. Pro models support USB 3 speeds up to 10Gb/s with a USB 3 cable; other models, and the cable in the box, run at USB 2 speed.

How do I use a flash drive with my iPhone?
- Plug the USB-C drive into the iPhone's port.
- Open the Files app and tap Browse; the drive shows under Locations.
- To move photos, select them in Photos, tap Share, then Save to Files and pick the drive.
A 2-in-1 drive with USB-C on one end and USB-A on the other also plugs into older computers: the MOVE SPEED YSULDP 2-in-1 comes in 32GB, 128GB and 256GB.
How fast is the iPhone's USB-C port?
On iPhone 15 Pro, 16 Pro, 17 Pro and 18 Pro models, up to 10Gb/s, but only with a USB 3 cable or a drive that plugs in directly and supports USB 3. The cable in the box is USB 2.
The iPhone 17 (non-Pro) runs at USB 2, up to 480Mb/s, so a large photo library takes longer.
Which drive should I get?
Size it to what you're moving: photos take far less space than 4K video. For big video files, a solid-state drive like the MOVE SPEED 1TB Type-C (up to 550MB/s) is much faster than a basic stick.
For computers only, the plain 16GB and 32GB USB drives are the budget pick.
Should I use a flash drive instead of iCloud?
Use both. iCloud backs up automatically; a drive gives you a second copy you control, and frees space without a subscription.
