Aside from a larger capacity and, not coincidentally, a higher price tag, there's barely any daylight between the two drives. Moreover, it's an impressive feat of engineering to double the capacity of an already spacious portable drive without adding any noticeable heft to its physical dimensions.
All the benefits of its previous iteration are here, so you get a compact, attractive drive that's formatted for your Mac. In terms of functionality and design, it's scarcely distinguishable from its predecessor, the Western Digital My Passport Studio (1TB) ($179.99 list, 4 stars), which is a good and bad thing. This makes sense, because it's arguably the only external drive-portable or otherwise-that most users will need for a very, very long time. So it's unsurprising that, above everything else, its enormity has garnered most of the attention. With 2 terabytes of capacity, the Western Digital My Passport Studio ($299.99 list) is the most capacious portable hard drive that we've seen thus far.
