How to Choose a Flash Drive for iPhone - Buying Guide

Your flash drive will be storing important data from your iPhone, so you want to make sure you're getting the most out of it. Here are some points to keep in mind to help you find your best flash drive. 

Check for “Made for iPhone” Certification

Check for “Made for iPhone” Certification

When looking for a flash drive for your iPhone, make sure to check for the “Made for iPhone” (MFi) certification that indicates that Apple has confirmed that the flash drive is compatible with iPhones.


This is important to do because flash drives that are not certified run the risk of not working properly or damaging your phone entirely. Connecting a normal USB flash drive using a Lightning-to-USB cord is not likely to work because most flash drives are not MFi certified.

Learn About the Related Transfer App

Learn About the Related Transfer App

Flash drives come with their own unique app to transfer content from your phone, so you want to make sure that the app is easy to use or understand. Some apps have an in-app camera that will automatically save photos as you take them or stream movies while the flash drive is plugged in.

Check for the Adapters You Need

Check for the Adapters You Need

Different devices connect to different adapters, so checking what adapters the flash drive has is integral to getting the most out of it. Most flash drives have a USB adapter, which is compatible with most computers.


Many flash drives come with multiple adapters, like micro-USB or type C adapters that can connect to Android phones, cameras, and newer Macbooks.

Ensure it's Compatible With Your Model and Files

More often than not, flash drives are compatible with the basic file formats, software, and iPhone models. However, you want to double-check that the flash drive you choose will support your iPhone model, data, and other devices.

Scan the Supported Files List

Scan the Supported Files List

Most, if not all flash drives for iPhone support the basic file formats like jpg, mp4, PDF, and mp3. Confirming that the data formats you want to transfer are supported is important for successfully using your flash drive. Most flash drives list out the supported formats, so you can always take a look.


One thing to note is that licensed materials aren't transferable due to the Digital Rights Management (DRM) system. Most media files downloaded by third-party applications are DRM protected. Some examples of licensed materials include iTunes data and library materials.

Keep Your Systems and Devices Up to Date

Keep Your Systems and Devices Up to Date

Most flash drives are compatible with recent Apple products and software. Sometimes, old iOS systems will not work with the flash drive's software. Conversely, there can be cases where newly released iPhone models or software clash with the flash drive, so peek at the software or device requirements as well as reviews for confirmation.

Figure Out How Much Protection You Need

Figure Out How Much Protection You Need

If you’re transferring private or sensitive data, you will want something that has protection. Consider the level of security you want, such as if both a password or Touch ID protection is required.

Make Sure the Flash Drive Has Enough Storage Space

Make Sure the Flash Drive Has Enough Storage Space

There is a range of storage space options available, from 32GB up to 1TB. If you catch yourself deciding between two storage options, sizing up is likely to be a better long-term investment


According to iClick, 64GB can store approximately

  • 39,321 photos that are 1.5MB
  • 42 movies that are about two hours (~1.5GB)
  • 14,757 songs that are 4MB
  • 201,326 PDF documents that are 300kb


Of course, it is important to keep in mind that these are averages that are to be used as a rough guideline. Factors such as the iPhone model and data type may affect the storage

Tips for Freeing up Storage on Your iPhone

Depending on how you use your iPhone, your photos and videos may not be what's taking up the most space on your iPhone - it might be the mysterious "Other" memory on your device. 


The video above teaches you what's in that "Other" category (like cache files) and, more importantly, how to free up that valuable space.
