A flash drive makes it a cinch to back up files, photos, videos, and more, or transfer files between your smartphone and computer, and the best flash drives for iPhones are uniquely compatible with your smartphone and offer plenty of storage space. They'll also transfer between devices at high speeds, thanks to USB 3.0 technology.

When shopping, you’ll want to make sure that your iPhone model is compatible with the flash drive. Unlike a standard USB flash drive, you'll need a drive with a USB connector on one end and — if you have an iPhone 5 model or later — a Lightning connector on the other. And if you want to upload and transport files from cameras, a flash drive with a micro USB port can also be good to have.

Another consideration is the quantity and types of files you’ll be transferring. Here's a brief cheat sheet that can give you an approximation of how many GB of storage space you'll need:

  • 32 GB holds about 20,000 photos or 21 full-length movies
  • 64 GB holds about 39,000 photos or 42 full-length movies

Most of the choices below support USB 3.0 transfer speeds, which are significantly faster than the previous USB 2.0 technology. With that in mind, scroll on for my roundup of the best flash drives for iPhones that'll have you covered in the digital storage department.


The Overall Best Flash Drive For iPhones

Given its reasonable price tag and great functionality, the SanDisk iXpand flash drive is a fantastic option for most iPhone users. Download the iXpand app, and when you plug in the drive, it'll automatically back up files and allow you to move photos and videos off your phone, freeing up storage space. There’s also an option to use the in-app camera to instantly take and store photos. The drive is outfitted with password protection, but there's no touch ID feature.

This drive features a Lightning connector that's attached to a flexible loop that fits through most iPhone cases and it works with USB 3.0. Plus, it comes in several storage capacities to suit your needs.

According to a reviewer: “I am not the most tech-savvy person, but I found this very simple to use. I followed a couple of basic directions off of the back of the package and, in just a couple of minutes, had downloaded all of my photos and videos from my phone. It gave me the option of deleting them from my phone once they were downloaded, making it a very clean process. I then transferred them to my desktop and found that process to be even simpler [...].”
