The buying question

Should I choose the USB-powered Toshiba Canvio Basics 2TB or the desk-based Seagate Expansion Desktop 6TB, and what setup should I expect on my computer?

The Toshiba is the portable, host-USB-powered option; the Seagate is a desktop drive with a separate included power adapter. Their documented Windows and macOS formatting notes also differ.

Quick verdict

When the recommendation changes
  • The recommendation changes if you use a Mac backup workflow: Toshiba says its NTFS-formatted drive needs reformatting for the macOS releases it lists, and Seagate says Time Machine use may require reformatting.
  • The recommendation changes if you cannot provide a separate power connection at the drive location; the Toshiba maker page describes USB-port power without an external AC cord.

The differences that matter

Power Source And Placement Workflow

Toshiba Canvio Basics 2TB (HDTB520XK3AA)

Toshiba describes Canvio Basics as powered through a laptop USB port and says no external AC power cord is needed. Its support page identifies HDTB520XK3AA as the Canvio Basics 2TB model.[1, 2]

Seagate Expansion Desktop 6TB (STKP6000400)

Seagate’s STKP6000400 datasheet lists an included 18W power adapter and USB cable and says setup uses both.[3]

What this changes: This is a placement and connection choice: the Toshiba suits a portable, host-USB-powered setup; the Seagate’s documented desktop setup uses a separate adapter as well as USB.[1, 2, 3]

The better fit depends on your priorities

Host Format And Initial Setup

Toshiba Canvio Basics 2TB (HDTB520XK3AA)

Toshiba lists the Canvio Basics as NTFS-formatted for Windows 10/11 and says reformatting is required for macOS 15.0, 14.7, and 13.7.[2]

Seagate Expansion Desktop 6TB (STKP6000400)

Seagate says the Expansion Desktop drive is automatically recognized by Windows or Mac without software installation; its datasheet notes that reformatting may be required for Time Machine.[3]

What this changes: If you plan to use macOS or a backup application, check the exact computer and workflow before copying files. Toshiba lists a reformat requirement for its specified macOS versions; Seagate’s automatic-recognition note does not remove its Time Machine reformat caveat.[2, 3]

The better fit depends on your priorities
