Buy this if

You prioritize rated transfer speed
You prioritize durability and water resistance
You prioritize security
You prioritize setup and compatibility

Skip it if

Skip a portable SSD if you need long-term archival storage — these are built for active use and fast transfers, not for sitting unpowered for years. And if your computer only has older, slower ports, the fastest drives here won't reach their rated speeds.

What to look for

Rated transfer speed

How fast large files move decides how long backups and media offloads take.

Durability and water resistance

A drive that survives dust, splashes, and knocks lasts longer in a bag or on location.

Security

Hardware encryption protects sensitive files if the drive is lost or misplaced.

Setup and compatibility

How the drive formats and sets up decides how quickly you can start using it across your devices.

How we chose

We synthesized this

You reach for an external SSD when a backup can't wait and a file has to move now — often with the drive in a bag, on the move. The right one depends on what you carry it through and what you put on it: daily backups, large media, or sensitive documents.

We weighed each drive against four things that matter in real use: rated transfer speed, durability and water resistance, built-in security, and how it sets up across your devices. The Samsung T7 Shield wins as the everyday pick because its IP65 rating shrugs off the dust and splashes that end an unprotected drive, while its read and write speeds stay fast enough for daily backups and transfers.

The alternatives cover sharper needs. The SanDisk Extreme moves large video and photo libraries faster, provided your computer has a capable USB-C port. The Crucial X9 Pro is slim and formatted for both PC and Mac without reformatting. And the WD My Passport SSD adds hardware encryption with password protection for anyone backing up sensitive files.

Every assessment here is a synthesis of documented specs and established use, not a timed lab test — you can read exactly what that means on our how-we-test page. Match the drive to how you carry it and what you store, and any of these will handle the backups and transfers it is chosen for.

Frequently asked questions

What size external SSD do I need?

Each drive here is the 1TB configuration, which suits most photo libraries and system backups. If you work with large 4K video projects, size up; if you only back up documents, a smaller capacity is enough.

Do I need a rugged drive?

If you carry the drive between locations or shoot on the go, the Samsung T7 Shield's IP65 dust and splash resistance is worth it. For a drive that mostly stays on a desk, the Crucial X9 Pro's slim design is simpler, though it has no water or dust resistance.

Will these work with both Mac and Windows?

The Crucial X9 Pro is formatted for cross-platform use between a PC and a Mac without reformatting. Any portable SSD can be reformatted for your system, but check the format before your first backup.
