What the specs mean for you

Data speed

5 Gbps

About 400 MB/s: fine for flash drives, hard drives, keyboards and webcams, and a bottleneck for fast SSDs.

Total ports

1

Compact: the essentials for travel or a light setup.

Why people pick it

  • Tiny: about 3.4g and 34mm long, small enough to leave on a keyring
  • Samsung rates it against water, shock, magnets, temperature and airport X-rays
  • Up to 400MB/s reads at 128GB and above
  • 5-year limited warranty
  • Strap slots on both the body and the cap (visible in Samsung's product photos)

Know before you buy

  • USB-C only: no USB-A plug or adapter for older computers
  • Samsung doesn't publish a write speed, only that it's lower than the read speed
  • The cap is separate and can be lost
  • 5Gbps USB 3.2 Gen 1 caps it far below a portable SSD for large transfers
