Review: Seagate Backup Plus 5TB portable hard drive
4.6Overall Score

Manufacturer: Seagate

What do you want from your portable hard drive? I want capacity and speed, preferably at a reasonable price. A solid state drive gives speed, but for high capacities the prices tend to be not so reasonable. Which brings us back to the venerable hard drive, with its spinning platters covered with fine-grained magnetic coatings and high speed heads hovering the tiniest of distances above them.

And the biggest of those, capacity-wise, in the hard disc world is the Seagate Backup Plus 5TB.

Yes, a portable drive in a smallish package with sufficient capacity for – well, just about any reasonable need.

As you can tell from the name, Seagate intends this drive for backup purposes, but I could see it being equally used in sneaker-net applications, particularly wide area ones.*

The drive uses Seagate’s high density drive platters – two of them I believe. So while in shape and overall size it’s about the same as what you’d expect from any 2.5 inch portable hard drive – 114.5mm by 78mm – it’s a bit thicker at 20.5mm and heavier at 247 grams.

It’s a fairly pretty thing in a business-like way. Most of the case is black, but the face is available in a red, black, blue or metal brushed aluminium. A 460mm removable connecting cable is provided. It has the USB 3.0 variant of the Micro-B USB connection at one end and a standard USB Type-A plug, with a blue tongue to indicate USB 3.0 support, at the other.

According to Windows the capacity of the drive is 5,000,845,586,432 bytes. By tradition and marketing imperatives, a terabyte is trillion bytes in the world of computer storage, not two to the fortieth power as it would be in most other areas of computing. That works out to 4.54 terabytes on those binary-centric factors.

Device properties as reported by Windows


There are a few files and folders in place on the drive as it comes out of the box. An icon for the drive, for example, and a PDF warranty document. There’s a hidden Autorun.inf file to attach the icon to the drive, and a hidden folder containing (down a few levels) the drive serial number in an XML file.

And there are two “Start Here” apps, one for Windows and one for Mac. These open a Seagate web page so you can register the drive and download Seagate Dashboard software which “protects and backs up the digital files on your computer”. I skipped that, since I prefer to use Time Machine and File History for my backup needs, and otherwise manually manage things, but others might find it useful.

Plugging it into my Windows machine, it popped up instantly. It was formatted for NTFS, the standard Windows high performance file system.

I started dragging in files to see how it went. Dragging in a 2.55GB video file, the copy took 21.6 seconds, with Windows indicating a speed of around 126MB/s. That was satisfyingly fast.

That’s more for the sneaker-net scenario. For

a better real-world example, I grabbed my “Documents” folder and dragged the whole thing into the drive. That had more than 27,000 files in nearly 2000 folders consuming 37.1GB of space.
