The Seagate Portable Drive (STGX2000400) is a 2 TB USB 3.0 external hard drive at £95.99, rated 4.5 out of 5 across 265,604 ratings, and it sits at number 2 in this guide. It is also the odd one out among the drives here: its two stated speeds agree with each other. The read speed is listed as 120 Megabytes Per Second; the data transfer rate is listed as 1 Gigabits Per Second, which is roughly 125 MB/s. Two fields, one answer, no gap of several thousand times.

Where this listing does fall apart is in the physical description. The same spec table calls the drive 3.5 inches and 7,200 rpm, which is the shape and the spin speed of a desktop unit. Then it gives the weight as 190 g, the thickness as 1.5 centimetres, the product features as "Portable", and the box contents as an 18-inch USB cable. It also lists the cache memory as 2 TB, which is the same number as the storage capacity. So the speed figures on this page are the believable part; the measurements of the object are not. Everything below comes from the Amazon listing for this drive and not from any testing we have done.

## Questions people ask

**How fast does Seagate say the Portable Drive is?**

The listing gives a read speed of 120 Megabytes Per Second and a data transfer rate of 1 Gigabits Per Second, which is about 125 MB/s. Those two numbers agree with each other, which is not the case for every drive in this guide.

**How much storage do I get?**

2 TB, stated in both the product title and the digital storage capacity field.

**Do I need to install software?**

No. Seagate says you connect the portable hard drive to a computer for automatic recognition, with no software required.

**What is in the box?**

The drive and an 18-inch USB 3.0 cable, as described in the product blurb.

**Does the Seagate Portable Drive work with a Mac?**

Seagate says it is designed to work with Windows or Mac computers and that backup is drag and drop; the hardware platform field lists Mac and PC.

**The spec table says 3.5 inches - is this a desktop drive?**

The form factor field says 3.5 Inches, but the same page gives a weight of 190 g, a thickness of 1.5 centimetres, a portable form factor and an 18-inch cable, which is the shape of a pocket drive rather than a 3.5-inch one.
