What to Look for in a USB-C Drive for Photo Backup
Any USB-C drive can hold your photos, but the right one makes backing up years of originals quick and painless instead of an all-weekend chore. Here are the four things that actually matter — transfer speed, capacity, file-system format, and durability — and how to weigh them.
Transfer speed
Speed is the difference between a backup that finishes over coffee and one that drags on for hours. A portable SSD is far faster than a spinning hard drive or a cheap USB flash stick, and it's what we'd recommend for photo backup. Look for a drive rated for USB 3.2 Gen 2 (10 Gbps) or faster; many portable SSDs advertise real-world speeds around 1,000 MB/s, which comfortably outruns what a phone can feed it.
One honest caveat for iPhone users: if your library is iCloud-optimized, the real bottleneck often isn't the drive at all — it's the time to download each original from iCloud before it can be written. Very Good Photo Backup tunes its parallel copies automatically to saturate whichever limit you hit, so you don't need to overspend chasing headline speeds you can't use. A solid mid-range SSD is plenty.
A fast portable USB-C SSD
A pocket-sized USB 3.2 SSD hits the sweet spot of speed, durability, and price for phone backups. We'll link a specific pick here soon.

Size for the library you'll have in a few years, not the one you have today. As a rough guide, modern iPhone photos run a few megabytes each and 4K video can eat 300–400 MB per minute, so video is usually what fills a drive. If you shoot a lot of video, a 1 TB drive is a sensible floor and 2 TB gives you real headroom. Because the backup is incremental, you can keep adding to the same drive over time — just leave room to grow.
File-system format: ExFAT or APFS
This one isn't optional. iOS can only write to a drive formatted as ExFAT or APFS, so whatever drive you buy, you'll format it to one of those first. Choose ExFAT if you also want to read the drive on Windows machines; choose APFS if the drive will live entirely in the Apple ecosystem. Either way, formatting erases the drive, so do it before you put anything on it.
A powered USB-C hub
Larger or bus-hungry drives run more reliably through a powered hub, which also lets you charge the phone while backing up. A pick is on the way.

A backup drive gets tossed in a bag and carried around, so build quality matters. Prefer a drive with a solid-state design (no moving parts to damage if it's dropped), a sturdy or rubberized shell, and a published drop or water/dust rating if you travel with it. A short, well-made USB-C cable that won't wiggle loose mid-copy is worth more than it sounds. For truly irreplaceable memories, consider keeping two drives and storing one in a different location.
Putting it together
For most people the answer is simple: a 1–2 TB portable USB-C SSD, formatted ExFAT, used with Very Good Photo Backup. That combination copies your originals at full quality into plain year-and-month folders, resumes if it's interrupted, and never touches your photo library beyond reading it. When you're ready to start, our step-by-step backup guide walks through the whole process.
