What are the Differences Between USB 1.0, 1.1, 2.0, 3.0?

The USB standard has changed our way of working with the PC. Thanks to eusbhubs, we can have a single cable to connect all kinds of devices such as external hard drives, cameras, scanners or printers.

As it could not be otherwise has experienced a great evolution since its inception, leading to the emergence of several versions:

USB 1.0. The first, designed to work with keyboards, mice, and devices that require a very small bandwidth. Allows to work an approximate speed of 1.5 Megabits per second. With this you’d need approximately 6 hours to copy a movie from 4 Gigabytes. It appears in the year 1996.

USB 1.1. As it could not be otherwise, and thanks to its success it does not take long to design another standard which surpasses the preceding. In this case, its speed is multiplied by eight to 12 Megabits per second. You can now copy that same movie in “only” 45 minutes. We are already in 1998.

USB 2.0. With this younemos a major leap. The speed is multiplied by 40 times to reach 480 Megabits per second. The film of the previous example would soon little more than 1 minute copied. We are already in the year 2000. It is very common to find PCs that incorporate both ports, USB 1.x and 2.0 then it is very important to know what these by connecting your devices, especially if you’re backing up very large files.

USB 3.0. It appears in 2008. Multiplies the speed up to 4.8 Gigabits, i.e. is 10 times faster than USB 2.0. The same movie would just take about 10 or 15 seconds to copy. Now the problem, for the first time, is not the cable if not the hard drive or device you connect sufficiently fast to be able to give you that speed.

One of its most important enhancements is that it also increases the amount of energy that can offer devices. Very important because every time we are more that we charge our phones and tablets using this cable.

The USB 3.0 and in the area of the disk external hard a competitor, the standard SATA 3.0 appears to http://www.eusbhubs.com/best/micro-usb-hub/. What I do in this case is to put a connector in the cabinet or box of the PC that is connected directly to the motherboard. The difference in speed between a hard disk external and internal is diluted. The SATA 3.0 interface is able to operate at 6 Gigabits per second.

Thunderbolt. The USB standard has achieved what its name suggests to become universal for almost any type of device that is connected to the PC. But there is one that definitely resists this and that connects your computer to the monitor. Thunderbolt is the creation that emerges from the collaboration of Intel and Apple in this regard.

Among its features is the ability to connect multiple monitors to the same cable. Another of their progress is internally carry a line of PCI Express. This allows you, among other things, that you may have a external graphics card to your computer that works as if it were connected internally, very useful if you want to have a laptop that you use to play at home with an external graphics and want the greatest autonomy possible when travelling with him.

In this case we would be talking about approximate speed of 20 Gigabits per second. Or just copy the same amount of information that has the movie for which the standard USB 1.0 needed 6 hours 3 seconds.
