Rank #3 in Best 4TB External Hard Drive 2026: 9 Ranked, Specs Compared
Toshiba Canvio Partner 4TB Portable External Hard Drive
Price and rating as shown on Amazon when we collected them. Both change.
The Toshiba Canvio Partner 4TB finishes third in this guide. It is a portable drive whose own page calls it both a 2.5-inch and a 3.5-inch unit, and it is the second-dearest of the nine, at £163.99. It also carries the largest review base here: 4.5 out of 5 from 12,648 ratings.
The spec sheet is where this one gets interesting. "Hard Disk Form Factor" reads "3.5 Inches"; a separate "Form Factor" field reads "2.5-inch"; the product title says 2.5''. All three sit on the same listing, so the size of the drive depends on which line you happen to read. Prices in this guide run from £89.91 to £169.94, and this one sits near the top of that spread. Everything on this page comes from the Amazon listing, not from any drive we have tested ourselves.
How those 12,648 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.

Questions people ask
Is the Toshiba Canvio Partner 4TB a 2.5-inch or a 3.5-inch drive?
The listing carries both. The "Hard Disk Form Factor" field says 3.5 Inches, while a separate "Form Factor" field says 2.5-inch. The product title and the description both say 2.5 inch, and the drive is described as a 2.5 inch mechanical hard drive.
What interface does the Toshiba Canvio Partner 4TB use?
The feature bullets and the specification fields say USB 3.0, quoting up to 5 Gbps. The product title says USB 3.2. The listing does not explain the difference between the two.
How fast does the Toshiba Canvio Partner 4TB transfer files?
The listing gives 5 Gigabits Per Second, and gives the same figure twice — once as Read Speed and once as Data Transfer Rate. That is the speed of the USB connection rather than a measured read speed for the drive itself.
Do I need software to use the Toshiba Canvio Partner 4TB?
No. Toshiba's bullet points say to plug the drive into a USB port and use it straight away, with no software or drivers required.
Is the Toshiba Canvio Partner 4TB compatible with a Mac?
The title says Mac and Windows compatible. The specification lists Mac under hardware platform and names Laptop, Desktop, Laptop, Smartphone and Mac under compatible devices, with the Sony PlayStation 4 listed under compatible games consoles.
How big is the cache on the Toshiba Canvio Partner 4TB?
The listing's "Cache Memory Installed Size" field reads "4" with no unit attached, so it does not state whether that means 4 MB, 4 GB or something else.
