Cloud storage is a racket. Honestly, paying $9.99 every single month just to keep your photos from vanishing feels like a subscription tax on your memories. Most people I talk to are hitting that "Storage Full" notification and immediately reaching for their credit cards, but there is a better way. You can backup iPhone with external hard drive setups and basically own your data again. It’s faster. It’s cheaper in the long run. And if the internet goes down, your wedding photos aren't trapped in a server farm in Virginia.
The reality is that Apple doesn't make this obvious. They want you in iCloud. But since iOS 13, the Files app has actually become quite powerful, and with the switch to USB-C on the iPhone 15 and 16, the physical bottleneck is finally gone. If you're rocking an older phone with a Lightning port, don't worry—you aren't left out, you just need a specific dongle.
The hardware reality check
Before you start dragging files, you need the right gear. Not every drive works out of the box. If you try to plug a massive, spinning platter desktop drive into an iPhone, nothing will happen. Why? Power. The iPhone can only output so much juice.
You want a portable SSD. The Samsung T7 or the SanDisk Extreme are the gold standards here because they are "bus-powered," meaning they run off the phone's battery. If you are using an older mechanical drive, you’ll almost certainly need a powered Lightning to USB 3 Camera Adapter. This lets you plug a charging cable into the adapter so the phone doesn't die while trying to spin up a physical disk.
Formatting is the next hurdle that trips everyone up. If your drive is formatted for Windows (NTFS), your iPhone will be able to see the files, but it won't be able to write to them. It’s a "look but don't touch" situation. You need to format the drive to APFS (Apple’s native format) or ExFAT (which works on everything) using a Mac or PC first.
How to backup iPhone with external hard drive manually
Most people think there is a giant "Backup Everything" button in the settings. There isn't. To backup iPhone with external hard drive manually, you’re mostly going to be living inside the Photos app and the Files app.
Open your Photos. Select the ones you want—or just select everything if you're feeling brave and have the time. Hit the Share icon. Scroll down to "Save to Files." This is where the magic happens. If your drive is plugged in, it will show up as a location under "Locations." Tap it, create a folder called "iPhone Photos [Date]," and hit save.
It's slow.
If you have 50GB of 4K video, your phone is going to get hot. That is normal. Just don't put it under a pillow while it's working. The Files app doesn't always give you a great progress bar, which is annoying. Sometimes it feels like the phone has frozen, but usually, it's just churning through data.
What about the "Everything" backup?
If you want a full system image—the kind that lets you restore your entire phone to a new device—you still need a computer. You can't currently create a full IMobileDevice-style local backup directly from the iPhone settings onto an external drive without a "middleman" like a Mac or PC.
On a Mac, you plug both the phone and the drive in. You tell the Mac to store the backup on the external drive by using a "Symlink." It’s a bit of a hack. You basically trick the computer into thinking the external drive is actually a folder inside the computer's own hard drive. It sounds complicated, but it’s just one line of code in the Terminal.
Why 2TB SSDs are the sweet spot
I see people buying 512GB drives to save money. Don't do that. Your next iPhone will probably have more storage than your current one. High-resolution ProRAW photos and ProRes video eat space like crazy. A 2TB SSD currently costs about what you’d pay for a year or two of high-tier iCloud storage. After that, it’s free.
There is also the speed factor. A direct cable connection via USB-C (on the newer iPhones) can hit speeds that make Wi-Fi look like a joke. We are talking 10Gbps on the Pro models. That’s the difference between waiting three hours for a backup and being done in fifteen minutes.
Common pitfalls and "Oh no" moments
The biggest mistake? Unplugging the drive too early. iOS doesn't have an "Eject" button like macOS does. The general rule of thumb is to wait about 30 seconds after the Files app looks finished before pulling the plug. If you pull it while it's writing, you risk corrupting the entire file system.

Another weird quirk is the "Optimized Storage" setting in iCloud. If you have this turned on, your phone doesn't actually hold your full-resolution photos. It keeps tiny thumbnails. When you try to backup iPhone with external hard drive, the phone has to download the full version from the cloud before it can move it to the drive. If your Wi-Fi is spotty, the process will fail. You have to go to Settings > Photos and check "Download and Keep Originals" a few days before you plan to do your big hardware backup.
The third-party software shortcut
If the manual Files app method feels too clunky, there are apps like iMazing or AnyTrans. These aren't free, but they handle the heavy lifting. They allow you to schedule backups to an external drive whenever you plug your phone into your computer.
I’m a fan of iMazing because it lets you browse your backups like a regular folder. You can go in and grab one specific text message thread from three years ago without having to restore the whole phone. That kind of granular control is something Apple just doesn't offer natively.
Actionable Next Steps
If you are ready to get your data off the cloud and into your desk drawer, follow this sequence:
- Check your port: If you have an iPhone 15 or 16, buy a USB-C SSD. If you have an iPhone 14 or older, buy the "Lightning to USB 3 Camera Adapter" and a standard SSD.
- Format the drive: Plug the drive into a computer and format it to ExFAT. This ensures you can read the files on both a Mac and a Windows PC later.
- Prep your photos: Go to your iPhone Photo settings. Ensure "Download and Keep Originals" is selected. Wait for the little circular loading bars on your photos to disappear.
- The First Transfer: Start small. Don't try to move 5,000 photos at once. Try 100. See how long it takes. Get a feel for the Files app interface.
- Verify: Once the transfer is done, plug that drive into a different device (like a laptop) to make sure the files actually open and aren't 0KB placeholders.
- Redundancy: A single hard drive is a single point of failure. If these photos are truly "once in a lifetime," buy two drives. Back up to both. Keep one at home and one at a friend's house.
Moving your data to physical hardware takes a bit of effort, but the peace of mind—and the lack of a monthly bill—is worth the initial setup. Stop renting your memories and start owning them.
