How We Chose These Hard Drives for Time Machine Backup
Each pick was assessed across 4 criteria weighted for real-world use.
- Connection
- We checked the USB standard and connector each maker names.
- Drive type and speed
- We recorded whether each drive is an SSD or hard drive and its read speed.
- Durability
- We noted listed drop, water and dust claims.
- Security and extras
- We checked for password protection, encryption and backup software.
What to Look for in a Hard Drive for Time Machine Backup
Key buying criteria so you get the right fit the first time.
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.
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.
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.
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.

Frequently Asked Questions
Which of these external drives has the largest capacity?
The My Passport 2TB, at 2TB. The Rugged Mini follows at 2TB, while the Seagate Portable 1TB has 1TB.
What is the least I can spend on one of these external drives?
At our last price check the YOTUO 1TB was the cheapest pick and the Rugged Mini the most expensive; the Expansion 1TB was the next step up from the YOTUO 1TB.
Is a portable SSD good for backups?
It works, but a hard drive gives more capacity per dollar for backups. Keep a second copy somewhere else for anything irreplaceable.
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.
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.
Bottom Line
Our first pick is the YOTUO 1TB, chosen for undercutting the Expansion 1TB on price when we checked. Look at the Expansion 1TB for a plain plug-in design, the Seagate Portable 1TB for PC, Mac, PlayStation and Xbox compatibility and the My Passport 2TB for backup software with ransomware defense if those matter more to you.
Choose a drive at least twice the size of the data you back up.
