Hook up a smartphone or a tablet, and you can charge them from the power coming through the Seagate model, something which you can't do with the WD My Passport.īoth these drives come with USB 3.0 ports, so in terms of connecting up to your desktop or laptop computer there's not much to choose between them.

In the case of our WD My Passport vs Seagate Backup Plus comparison, the read and write speeds seem to be broadly the same, but you can get more space with the Seagate drive: it maxes out at a massive 14TB of capacity rather than the 5TB maximum offered by the WD unit.Īnother advantage of a bigger, separately powered hard drive is that you can run other devices off it – and the Seagate Backup Plus comes with two USB-A ports on the front that let you connect up other accessories, like flash drives or card readers. In terms of portability, the Western Digital model wins out.Įxternal drives requiring their own power supply have advantages too though: they're typically faster, and offer greater capacities.
