Photo libraries grow fast, so capacity per dollar favors hard drives. Every pick is a hard drive, ordered by capacity.
Our comparison rests on published figures for drive type, capacity (as reviewed) and connection; nothing here was tested in-house, and where a maker leaves a figure out, we say so.

Our Picks
Largest Capacity1 of 4
WD My Passport Ultra for Mac 5TB on Amazon (opens in a new tab)
WD's My Passport Ultra for Mac arrives formatted for macOS and connects by USB-C.
Best for
- Buyers who put capacity first.
Skip if
- If budget leads, the Expansion 1TB was cheaper at our last price check.
Why we like it
It adds 256-bit AES hardware encryption and the largest capacity here, 5TB. Nothing else here matches its 5TB capacity; the Seagate Portable 2TB comes closest at 2TB. A USB-C (USB 3.1) connection is unique to it among these picks, while the Expansion 1TB uses a USB 3.0 connection.
It also comes with formatting for Mac out of the box, a metal cover and a USB-C connection. As a spinning hard drive it is slower than an SSD and less tolerant of knocks while running. It was the most expensive pick when we checked, so weigh what it adds over the My Passport 2TB.

How We Chose
Each pick was assessed across 4 criteria weighted for real-world use.
- Connection
- We checked the USB standard and connector each maker names.
- Durability
- We noted listed drop, water and dust claims.
- Security and extras
- We checked for password protection, encryption and backup software.
- Drive type and speed
- We recorded whether each drive is an SSD or hard drive and its read speed.
What to Look for in an External Hard Drive for Photos
Key buying criteria so you get the right fit the first time.
SSD or hard drive
A portable hard drive gives the most terabytes per dollar and suits backups. A portable SSD is several times faster, lighter and more tolerant of drops, which suits working files and games.
Size for what you store
1TB suits documents and a few games. 2TB or more suits photo libraries, video and large game libraries. Hard drives reach larger sizes for the money.
Drop and water ratings
IP ratings and drop heights are manufacturer claims. They matter for drives that travel in bags; a drive that stays on a desk needs less.
Match the port
A 1,050MB/s SSD needs USB 3.2 Gen 2 (10Gbps); a 2,000MB/s SSD needs Gen 2x2 (20Gbps), which few laptops and no Macs offer. On a slower port the drive simply runs at the port's speed.
Password and encryption
Hardware encryption with a password protects a drive that could be lost. Software-only encryption depends on an app being available on each computer.
Mac and Windows formatting
Many drives ship formatted for Windows. On a Mac, reformat to APFS for Time Machine, or exFAT to share the drive with a Windows PC.

Frequently Asked Questions
Which pick leads on capacity?
The Passport Ultra for Mac leads at 5TB, ahead of the Seagate Portable 2TB at 2TB; the Expansion 1TB sits at the other end with 1TB.
Which pick costs the least here?
At our last price check the Expansion 1TB was the cheapest pick and the Passport Ultra for Mac the most expensive; the Seagate Portable 2TB was the next step up from the Expansion 1TB.
How long do portable drives last?
It depends on use and handling. Check the warranty length as a signal of the maker's confidence, and replace a drive that reports errors.
Does the cable matter?
Yes. Use the included cable or one rated for the drive's speed; a charging-only or USB 2.0 cable limits transfers.
Why does my 1TB drive show less space?
Drive makers count 1TB as one trillion bytes; Windows counts in binary units, so it shows about 931GB. No space is missing.
Bottom Line
Our first pick is the Passport Ultra for Mac, chosen for the largest capacity here (5TB). Look at the Seagate Portable 2TB for an 18in USB 3.0 cable, the My Passport 2TB for backup software with ransomware defense and the Expansion 1TB for a lower price than the Seagate Portable 2TB and the rest when we checked if those matter more to you.
