What is USB 3.0?
Dubbed 'SuperSpeed USB', USB 3.0 represents the next generation of connectivity between computers and peripherals (digital cameras, portable media players, mobile phones, external hard drives, and so on). It replaces the current 'Hi-Speed' USB 2.0 standard.
As the USB-IF explains: "SuperSpeed USB brings significant performance enhancements to the ubiquitous USB standard, while remaining compatible with the billions of USB enabled devices currently deployed in the market. SuperSpeed USB will deliver 10x the data transfer rate of Hi-Speed USB, as well as improved power efficiency."
Just how fast is USB 3.0?
The new specification is rated 10 times faster than USB 2.0, which has a maximum transfer speed of 480Mbps.
In comparison, USB 3.0 has a theoretical peak throughput of 5Gbps. This means that USB 3.0 is capable of transferring a 25GB file in approximately 70 seconds.
If that doesn't warrant a shout of "whoosh!" then what does? In contrast, USB 2.0 would take around 14 minutes to perform the same task. And you'd be twiddling your thumbs for around 9 hours if you used USB 1.1.
This speed boost makes USB 3.0 ideal for the sort of large-scale file shunting we all do today, such as copying large images, MPEG-4 video clips, or making data backups to portable hard drives.
USB 3.0 isn't just fast, it's bi-directional
Unlike USB 2.0, where data can only be piped in one direction at a time, USB 3.0 features the ability to read/write data simultaneously.
This is achieved by adding four new connections to the old USB 2.0 connector – two for transmitting data and two for receiving data. This brings the total number of connections on a USB 3.0 connector to eight (compared to four for USB 2.0).
