Do you guys want to know about the USB 3.0 what is it, what features it has, what advantages of USB 3.0 vs USB 2.0 and how can we know which port is USB 3.0? Then you came at the right place.
Here we have explained USB 3.0 in details. This is just the simple guide of USB 3.0. Now let’s not waste time and get to know about USB 3.0.
USB 3.0 Explained
While copying that favorite TV series or movies of ours in our laptop, we barely give a thought on which USB port to use for the transfer. And why should we? All those rectangular ports are the same, right?
Get your laptop and closely look at the tiny design engraved next to the USB ports of your laptop. Did you find any difference?
In most laptops, you’d notice ports marked with one of these 2 designs:
This one above is the regular USB 2.0 port.
However, this one marked with “SS” is the Super Speed USB 3.x.
Super Speed USB has new modes specially added for data transfer, due to which it is more than 10 times faster than the regular USB port provided you are using a USB 3.0 storage device.
In many laptops, however, you might not find the “SS” mark. Another way to know the SS port is to check the color inside the port. USB 3.x ports are generally colored blue inside, like in this image:
On Apple computers: About This Mac → More Info… → System Report… → Hardware → USB
Many of you might know it already, but I haven’t seen many practising it.
So, the next time you need to copy all those seasons of your favourite show or an Ashutosh Gowariker movie, try this trick! 😉
USB 3.0 Specifications
A number of changes have been implemented in USB 3.0 to satisfy the increased demands of external devices. Here is a quick USB technology overview:
This USB 3.0 has really superfast transfer rate. It around 3200 Mbps or 3.2Gbps. And the theretical top signaling rate is at 4.8 Gbps.
USB 3.0 has full duplex data transfer. Two of five lanes are reserved for transmitting data, while another pair is dedicated to receiving data, meaning that USB 3.0 can read and write data simultaneously at full speed.
The USB 3.0 takes 4 V than 4.4 V in USB 2.0
USB 3.0 suspends device polling, which is replaced by the interrupt-driven protocol. As a result, idle devices won’t experience a power drain since a signal from the device is required to initiate data transfer. With USB 2.0 the host controller used to look for active transfers, slowly draining power.
