On every laptop or computer you might have a USB that is blue and black or white? What are the differences between USB 3.0 and USB 2.0, every USB be it 2.0 or 3.0 undoubtedly has a difference whether it's advantages or disadvantages in USB 3.0 or USB 2.0.
Definition of USB
USB stands
for hard disk, printer and camera. The first time USB was introduced by the world in 1996 was the first USB to be introduced, namely USB 1.0, and in the early 2001's USB 2.0 emerged and became popular. With USB 2.0 capabilities that exceed 40x USB 1.0 speeds of USB 2.0 around 480MBits / s or 57MBytes / s.
Then in 2010 it was introduced to the world that is USB 3.0, USB 2.0 is known as the High-Speed while for USB 3.0 it is termed Super-Speed. The term Super-Speed is the reason that the speed of USB 3.0 is said to be very fast.
After several changes to USB 2.0 were implemented on USB 3.0 along with the increased use of external devices and the need for super fast or high speed speeds, under a brief clarification of the discourse of USB 3.0 technology
1. Data Transfer
USB 3.0 introduces a two-way or full duplex transfer technology, so that USB 3.0 is able to read and write data simultaneously. Previously, USB 2.0 and USB did not support this bi-directional technology or this two-way technology.
2. Transfer Rate
The data transfer speed that is owned by USB 3.0 is around 3200MBits / s or 3.2GBits / s or 400MBytes / s. With the theory that USB 3.0 can reach speeds of 4.8GB / s, this speed is 6 to 10x faster than the maximum speed that USB 2.0 has.
3. Power
The voltage on USB 3.0 is reduced from 4.4V to 4V, then the current is also increased to 150mA so that in addition to more energy efficient. USB port 3.0 is also able to use 4-6 devices and can increase recharging.
4. Physical form
The other end of USB 3.0 is the same as the USB 2.0 end, but the USB 3.0 cable will have more inside, there is a supplement of 4 cable lines compared to USB 2.0 there are 9 cable lines in total.
The advantages of USB 3.0
Nowadays there are many electronic devices that still use USB 2.0, what if later they have started using USB 3.0? In this case no need to worry, the reason is that USB 3.0 has advantages such as the following:
USB 3.0 compatibility
USB 3.0 is compatible with USB 2.0, so USB 2.0 devices will still work on USB 3.0 ports and will run at standard USB 2.0 speeds. But it cannot be vice versa, USB 3.0 devices cannot be installed in USB 2.0 ports.
Operating System Support
Windows Vista, Windows 7 and Linux already support USB 3.0, and Mac will soon follow. But for Windows XP until now there is no certainty whether there will be an update for this brand new interface.
Lack of USB 3.0
In addition to having various kinds of advantages above, the USB 3.0 interface also has several shortcomings, including the following:
Cable Length.
The maximum length of a USB 3.0 cable is reduced to 3 meters (maximum USB 2.0 is 5 meters). Although this can be overcome by adding a USB Hub.
Speed Limit
Not all devices can make full use of USB 3.0 speeds, resembling the example of a Magnetic Hard drive which is limited to the speed of the disk's spinning halves.
That is the clarification of the discourse between the differences between USB 3.0 and USB 2.0 so it can be useful for those of you who are reading it. If there is a wrong word or there are words that are not polite to apologize. Don't forget to leave a comment and share this article with your best friends.
That is all and thank you
