Sixth in our guide to 5 TB external hard drives, the Seagate One Touch Portable is a 2.5-inch USB drive in a brushed metal enclosure, listed at £191.99 with 4.6 stars from 3,874 ratings. Unlike some drives above it in the guide, its capacity numbers agree with each other: the product name, the Digital Storage Capacity field and the Hard-Drive Size field all say 5 TB.

The disagreement on this one is about speed. The same listing gives a Read Speed of 120 Megabytes Per Second and a Data Transfer Rate of 480 Megabits Per Second. 120 MB/s is roughly 960 Mb/s, about double the 480 Mb/s the same page also declares — and 480 Mb/s is the ceiling of a USB 2.0 connection, on a product whose title says USB 3.0. There is a third speed field too, Media Speed, written as 1.2E+2 megabytes_per_second, which is the same 120 in scientific notation. Everything on this page comes from the Amazon listing for this drive, not from any testing we carried out.
