The Best External SSDs

Five external SSDs compared by interface, rated read speed and durability, so you can match a drive to the ports your computer has.

By The PC Journal editorial team

12 min read5 products evaluated

An external SSD's rated speed depends on the port it plugs into. A 10Gbps USB port tops out around 1,050MB/s, a 20Gbps Gen 2x2 port around 2,000MB/s, and only USB4 or Thunderbolt reaches the 4,000MB/s class.

We researched five portable SSDs across those three tiers using their Amazon listings and prices at the time of writing. We did not test them; speeds are manufacturer maximums.

If budget leads, the One Touch SSD 2TB was cheaper at our last price check.

Why we like it

It adds IP55 water and dust resistance, a 7.5ft drop rating and password protection built into the drive. It reads at up to 2,100MB/s and is rated IP55 with 7.5-foot drop resistance. Full speed needs a 20Gbps USB port.

On capacity it ties with the T9 2TB, the T7 Shield 2TB and the One Touch SSD 2TB at 2TB. On rated read speed it sits mid-pack at 2,100MB/s: the Rugged SSD4 offers 4,000MB/s, and the One Touch SSD 2TB comes in at 1,030MB/s. You get an SSD password protection security here, which sets it apart from the Rugged SSD4 and its a none stated security. You also get a lanyard loop and activity light and three months of Mylio Photos+ and Acronis True Image.

Best for

USB4 and Thunderbolt computers

Skip if

Skip it if capacity matters most to you; the X10 Pro 2TB offers 2TB.

Why we like it

Skip if

If budget leads, the One Touch SSD 2TB was cheaper at our last price check.

Why we like it

Its IP65 rating and 9.8ft drop protection suit a drive that lives in a camera bag. It matches the X10 Pro 2TB, the T9 2TB and the One Touch SSD 2TB on capacity (2TB). Its 1,050MB/s rated read speed ranks fourth of 5 here, behind the Rugged SSD4 (4,000MB/s) and ahead of the One Touch SSD 2TB (1,030MB/s).

You get a USB 3.2 Gen 2 connection here, which sets it apart from the One Touch SSD 2TB and its a USB 3 (as listed) connection. Like the Rugged SSD4 and One Touch SSD 2TB, it has a none stated security, while the X10 Pro 2TB uses an SSD password protection security. It also offers Magician software for drive health and firmware updates. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Rugged SSD4 and the rest.

How We Chose These External SSDs

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 an External SSD

Key buying criteria so you get the right fit the first time.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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

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.

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.

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.

Can I run PC games from an external SSD?

Yes. Launchers such as Steam can add a library folder on an external drive. Load times depend on the drive and port; an SSD on a 10Gbps port is far quicker than a hard drive.

Will these work with PS5 or Xbox?

Consoles can store and play older-generation games from USB drives. Current-generation games usually must run from internal storage; check the console's own rules.

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

The Crucial X10 Pro is the all-round pick, pairing 2,100MB/s reads with IP55 protection and password security. The Samsung T9 suits long transfers on a 20Gbps port, and the LaCie Rugged SSD4 is the choice for USB4 and Thunderbolt computers.

On a 10Gbps laptop, the Samsung T7 Shield adds IP65 and 9.8ft drop protection, while the Seagate One Touch SSD gives 2TB at the lowest price here.
