Portable hard drives are everywhere these days. Everyone has one, and most people are looking for something with greater capacity. One deterrent to purchases, though, is that interfaces keep changing as faster ones come to market. Happily, Seagate’s GoFlex portable hard drives feature a standard USB 2.0 interface, but can be upgraded later on.
Unless you are on the bleeding edge of technology, chances are you haven’t used a USB 3.0 device yet. And unless you’re constantly reading up on the latest and greatest technology, you might not even know what USB 3.0 is all about.As the name implies, USB 3.0 is the successor to the ubiquitous UBS 2.0 interface. It provides faster transfer rates -- up to 5.0Gbps using a technology dubbed SuperSpeed. This is more than ten times the speed of USB 2.0 and, while you won’t get speeds like that in real-life use, you will see significant improvements over USB 2.0. It is also significantly faster than eSATA, FireWire-800, and FireWire-400.
