USB 3.0 is the latest generation of USB technology . It has redefined the limits of data transfer and connectivity between computers. It is both a specification and a technique that has helped to achieve much higher data transfer speeds than the earlier USB 2.0 standard. Speed is the major advantage of USB 3.0 over USB 2.0 and rightly so , it has also been named Super Speed. USB 3.0 standard was implemented in 2008 and the first devices certified according to this standard thronged the market at the CES show at Las Vegas in 2010 . The technology is recent and there are many new devices that will be made USB 3.0 compatible in the coming years.
USB 3.0 vs USB 2.0 : How is USB 3.0 different from USB 2.0 and technological advancements .
- Transfer Speed of data : In USB 3.0 the transfer speed is at maximum 5 Gbit/s ( Gigabyte per second ) which is significantly higher than what USB 2.0 could offer . USB 2.0 has a data transfer speed of maximum of 480 Mbit/s . Given its maximum speed is wonderful, USB can conveniently touch top speeds of 3 Gbit/s to 3.2 Gbit/s consistently. You can easily verify this by checking the data transfer speed from your USB 3.0 pendrive ( flash-drive ) and comparing it with USB 2.0 compatible flash drive. Since, USB 3.0 ports can also charge devices like mobile phones , it will take much less time to charge them fully. This is a great development.
- Power Efficient : USB 3.0 enabled devices are more efficient users of power than USB 2.0 and this actually saves a lot of power . You can imagine this as there are more than billion of USB 3.0 enabled devices like flash drives already with the consumers.
- More Powerful in terms of driving devices that require more power . For example USB 3.0 enables higher current for hardware like high speed portable drives. That means, as and when you need more power, USB 3.0 will supply . Else, it will use power judiciously.
- USB 3.0 has more bandwidth capability than USB 2.0 that enables transfer of higher amount of data to and fro a USB connection.
However, these seemingly simple changes require a complete reworking of the way devices are connected and data is transferred. USB 3.0 thus has more pins and connections than a USB 2.0 connector. Good news is that USB 3.0 is backwards compatible with USB 2.0 which means that USB 3.0 connectors will work correctly in USB 2.0 slots.
USB 3.0 devices have led to better user experience for people. USB 3.0 connection between computer and device is fast and unhindered. Devices that task the USB 2.0 type connection use lot of bandwidth. USB 2.0 cannot provide the speed required to perform many such operations which have now become possible with the coming of USB 3.0 connections . USB 3.0 enabled devices like flash drives let you transfer your files much faster. Things like USB 3.0 video cards were much desired. Operating systems like Windows 8 and Mac have already released USB 3.0 drivers . USB 3.0 external hard disk drive, USB 3.0 video adapters , USB 3.0 docking stations are some of the high end USB 3.0 enabled devices that advance our multimedia experience. Connectivity between computer and mobile has improved. Smartphones can be charged much faster using a USB 3.0 cable connector. Portable media players will perform better and without glitches.
USB 3.0 hubs further enhance connectivity and enable you to get a more high end network for your devices . Connecting and using external USB enabled devices on a computer got better and richer .
