Well most of us must be aware of the integration of the USB 3.0 in the devices being developed at the moment. In case you don’t know much about it and are wondering what are the major improvements or why should you use USB 3.0 instead of USB 2.0 anymore, then here are the details.
USB 3.0 is the next version of the USB ports being used today worldwide in the gadgets developed these days. This port is backward compatible with USB 2.0 also, which means that if you have a USB 3.0 device then it will work perfectly with your USB 3.0 computer and also with your USB 2.0 system without any extra cable or attachments.
There is a vast improvement of the speed if using USB 3.0 compatible devices as compared to USB 2.0 devices. Theoretically USB 3.0 claims to be around 10X faster than the USB 2.0 that is if you are using USB 2.0 device then at the maximum your device can have the transfer speed of around 480Mbps whereas using USB 3.0 can fetch you at the max speed of 5Gbps.
I have my external hard disk (USB 3.0) which I use on my USB 3.0 laptop and in reality you may not get this speed owing to a variety of factors, but you can always expect it to be 4 to 5 times faster than using with USB 2.0.
The first time I figured out the transfer speed difference between the two ports, made me buy this new Hard Disk instantly. So if you are planning to purchase either a new system or a device, then you should go for USB 3.0 only, as this is something which is there to stay (at least for some time now).
