This week, Lexar showed us a whole bunch of products, most of which culminated around the concept of USB 3.0. While everyone knows that USB appears in most parts of their lives – phones, media players, keyboards and mice – the third iteration promises to bring more to the table.
Available for well over a year now, USB 3.0 isn’t exactly new. Gadget aficionados have probably seen it in the marketplace since it started appearing in selected computers and motherboards in 2010, but the new format still hasn’t found its way into every computer.
In fact, even today – two years after the products launched with the new version of USB – we’re still seeing laptops released that only feature USB 2.0.
So what does USB 3.0 offer?
Most notably, the format offers a speed improvement for data transfer, roughly ten times faster than USB 2.0, in fact.
While USB 2.0 maxed out at 480Mbit/s – roughly 60 Megabytes per second – the new USB 3.0 standard is capped at 5Gbit/s, or roughly 628 Megabytes per second. These are maximum speeds and not guaranteed, but you can expect faster data transfer rates, meaning that moving files to and from USB 3.0 thumb drives and hard drives will be faster.
How do I know if I have it
There is an easy way to find out if your computer supports USB 3.0, and that’s by looking at it.
While USB 2.0 has predominantly arrived with a black plastic connector, it’s also been made in white for Apple’s iPhone charge cable.
In USB 3.0, the connector is blue, allowing you to quickly see whether you’ll receive the full speed experience that is the new USB.
To get the USB 3.0 speeds, both the connector on the device and the USB port on the computer need to be blue, otherwise you’re connecting USB 2.0 to USB 3.0.
One of the primary reasons why USB 3.0 is important is the speed at which it brings to the table, a much faster transfer rate that’s sure to impress the most data hungry individuals.
But one other important factor is that it’s backwards compatible with the existing USB format.
In USB 3.0, the port stays the same, but the technology improves, meaning you can plug in all your old USB devices and they’ll still work, drivers permitting.
Devices with USB 2.0 connectors can plug into the blue USB 3.0 connections on computers, and vice versa, but you’ll only receive USB 2.0 speeds.
