Our verdict

A plain portable disk for backing up a laptop with drag and drop and no software to install. Moving platters make it slower than flash storage, so it suits archives and copies.

Overview

Not a pocket SSD, this Seagate unit is a mechanical drive in a slim plastic shell that a computer recognizes automatically. A short USB cable connects it, and files move by drag and drop.

Everyday backups and an archive of photos or documents are what the drive does well, and setup needs no software on Windows or macOS. The limitation is the moving platters, which make large copies slower and call for gentle handling.

Who it's for

A home or office laptop that needs a regular backup suits this kind of disk, and the listing names a console as compatible too. Those who copy large video files daily, or carry the drive in a loose bag, may prefer flash.

Pros and cons

Pros
  • Drag and drop setup
  • No software required
  • Works with Windows and macOS
  • Slim and light body
Cons
  • Mechanical drive, slower than flash
  • Fragile if dropped while spinning
  • Warranty limited to one year
  • Cable is short

Performance notes

Data passes through a moving read head, so speed varies with file size and how full the disk is, and the USB link caps the top rate. Many small files copy slower than a few large ones. A computer should eject the drive before unplugging so the head parks safely.
