There’s more to today’s external hard drives than just tacking on extra terabytes. Joel Burgess and Paul Taylor investigate.

LABS TEST RESULTS External storage

Physically, external hard drives have continued to shrink over the last decade, and they’ve almost reached the point where their size is starting to be limited by the constraints of having a mechanical spinning disk. But just because external hard drives aren’t signifi cantly reducing in size doesn’t mean that the’re not developing in other ways.

USB 3.0 is now basically commonplace and the additional power it can deliver (along with faster transfer rates) means that larger, more power-hungry drives can run without needing a dedicated power cord. Testament to this is the new 3TB My Passport Ultra from Western Digital – a pocket-sized portable which offers as much space as entry-level desktop drives. This newfound capacity for portable drives has been eating into the external desktop drive market, making dedicated ‘wall powered’ drives harder to come by – despite putting an open call out to all the major drive vendors, we only received one of the latter for this feature.

Another complicating factor in the external-storage equation is the emerging wireless hard drive category. These are targeting smartphone and tablet use as much as PCs and laptops. As our mobiles become more important to us and streaming home media technology becomes more attainable, hard drives that can back up data from a range of devices are taking more of the spotlight from plug-bound options.
