The ports were also present in the world of computers for a long time. Like the joystick, printer, keyboard, and even mouse which need to be connected to the ports.
Advancement continued and then came a small device that can do better than the former storing devices. The USB is also known as Universal Serial Bus.
Mainly it is used to transfer data from one computer to another. It can be used for many other connections. Also like connecting the keyboard, to the computer or the mouse, the music players and also other drivers.
The USB does wonders. Like it even supplies power to other devices like smartphones, tablets, and even charge batteries. It helps in connecting peripheral devices like the digital camera or scanner, external hard drives, and many more.
There are many types of USB ports, the first one is the USB 1.x. The USB 1.x transfers data at a speed of 12 Mbps. The second one is USB 2.0. It transfers data at a speed of 280 Mbps.
The third one is USB 3.0 the transfer speed is up to 5 Gbps. And lastly USB 3.1 the transfer speed is up to 10 Gbps second. USB was created in the 90s.
Because the need for transfer and connectors was increasing. And as years passed, the USB had become a very common device in the world of electronics.
Desktop computers have more than 10 USB ports altogether. The laptop computers consist of at least 4 USB ports because of its size and portability.
Whereas, the tablets and smartphones consist of charging USB ports for charging the device. Not only computers but there are many other devices that use USB ports to transfer and connect from external drives, keyboard, and keypad to webcams and Thumb drive.
The USB comes in many different connector sizes. The three common USB connectors are the Micro USB, Mini USB, and the C type or USB(C type). USB cables come in many lengths.
From 3 feet to at least 15 feet. The transfer speed among the two mainstream USB is important. The USB 2.0 and USB 3.0, the speed differs between the two.
Even though they both are quite faster than the former USB. USB 2.0 came out in the year 2008. It gained a lot of popularity then. The other name for USB 2.0 is Hi-Speed USB.
With the name given one can understand how fast it can transfer the data. The maximum transfer speed is 480 Mbps. It is even inexpensive and provides 500 mA power.
It comes with the black “block”. The USB 2.0 is a USB having only a one-way connection path. For instance, the path used to transfer data and receiving data is the same.
It can either transfer or receive data. One at a time. It cannot do both. On the other hand, USB 3.0 has gained a lot of popularity lately. It was released in the year 2008.
It was the successor of the USB 2.0. It is known as the fastest USB. The other name for the USB 3.0 is SuperSpeed USB. Which can transfer 5 Gbps. It is very fast even faster than USB 2.0.
The latest version of the USB 3.0 is the USB 3.1. It is also known as SuperSpeed+. It was released in the year 2013. It can transfer up to 10 Gbps. The USB 3.0 comes with the C type connector.
It is also a mainstream type of USB. It is used for smartphones and many other devices. The power provided by the USB 3.0 is 900 mA current. It is a two way communication drive.
Devices that have a USB 3.0 drive can be compatible with the USB 2.0 port. But if one attaches the USB 2.0 port in a USB 3.0 drive then the drive will work but it won’t have much speed as expected by the user.
Just like the speed in the USB 2.0 connector. To avail proper and better speed. The USB 3.0 should be put in the USB 3.0 port. While the price between the two is different.
And the gain of the popularity of the USB 3.0 has increased. USB 2.0 is still used but less. Both of the USB have advantages and disadvantages. The decision of the user should be taken after comparing these two USBs closely.
Differences between USB 2.0 and USB 3.0
There are very crucial differences between the two USBs. It even talks about how the former USB is being replaced by the latest USB.
1. Physical Features
The USB 2.0 connector does not look the same as the USB 3.0. If one looks closely then one can see the minor and important difference. The USB 2.0 connector has a “block” that is black in color. It is found inside the connectors or the USB connectors. Sometimes the block may even be white in color.
The USB 3.0 connectors and ports do not have a black block. But the color of the block is blue. Therefore, the small difference between the two USB is differentiated with the help of the block color.
2. Number of wires
The number of wires differ a lot between the two USBs. The USB 2.0 has at least four wires. These wires in the USB 2.0 affect the speed of the USB 2.0 connector and the device.
The USB 3.0 has more wires than the USB 2.0. It consists of at least more than five wires than the USB 2.0. Making it a total of nine wires. The more wires lead to more speed in the USB connector and the device.
The former connector, the USB 2.0 is a predecessor of the latter. The speed may differ among them. The speed provided while transferring data using a USB 2.0 is 480 megabits per second or Mbps. It provides 10 times lesser speed than the USB 3.0.
The latest and the latter, USB 3.0 is a popular connector. It is because of the speed it provides. USB 3.0 provides at least 10x speed than the USB 2.0. The transfer speed is 400 Mbps or megabits per second.
Since the USB 2.0 is older than the USB 3.0. It has limitations: the USB 2.0 can only provide one way path for the communication. For instance, the connector can only receive or transfer the data one at a time. Both receiving and transferring is not possible in the USB 2.0.
Being quite popular and speedy, the USB 3.0 allows both ways for communication. The USB 3.0 uses the technique of “unidirectional” data path which is 2 and separate. One directional data path sends data and the other directional path receives data. Both receiving and transferring data can be done together, unlike the USB 2.0.
5. Power usage
The USB 2.0 can give or deliver up to at least 500 mA (milliampere) which is less than the current delivered by USB 3.0.
While USB 3.0 delivers and provides up to at least 900 mA current. This affects the transfer and makes it faster than the former. The USB 3.0 drives can be charged faster. It is also beneficial for the USB 3.0 devices which consume a lot of power or current. It loses less time and is very easily done.
Using a USB 2.04 and USB 3.0 drive will be compatible. But the speed provided will be less than the latter. For instance, if one USB 2.0 port is used in a USB 3.0 drive. Then the USB 2.0 port and the USB 3.0 drive will provide the same speed as the speed of the USB 2.0 port and drive.
The USB 3.0 port works normally with a USB 2.0 drive. The port and drive of the latter and former are totally compatible. But to avail a better high speed and data transfer it is recommended that a USB 3.0 should be attached to 3.0 drive.
7. Better USB
The latest version of the USB 3.0 series is the better USB found in the market. The USB 2.0 is very bland in front of the USB 3.0 and the USB 3.1. The USB 3.1 is 20x faster than the USB 2.0. The transfer, rate, power, and wires are more than the USB 2.0 and are much better.
There is a competition between the USB 3.0 and USB 3.1. The “block” colors differ even though they fall in the same series. The USB 3.1 has a red “block” inside the connector. The data transfer in USB 3.1 is 2x faster than the USB 3.0. The transfer speed is up to 10 gigabytes per second.
USB 2.0 is a little inexpensive than the USB 3.0. It is quite affordable and easily found in the market. If one is looking for normal use and transfer of files and data. Which does not have to do with the expensive USB 3.0. Then USB 2.0 is a better USB to go for. The approx price for the USB 2.0 is less than $8.
The USB 3.0 is comparatively expensive and very popular in the market. It is because of the speed and the other features. If one is looking for fast transfer and better speed then the USB 3.0 is the best USB to go for. The starting price of the USB 3.0 is approx $6.
Which is Better – USB 2.0 or USB 3.0?
Now keeping in mind all the advantages and disadvantages. The USB 3.0 is much better than the USB 2.0. Even though they both are compatible. USB 3.0 is much faster and better to use than the USB 2.0.
So, it depends on the user’s preference and needs as to why the user requires a USB 2.0 or USB 3.0. If the user has nothing to do with the high speed of transferring files and data and wants USB for less price.
Then USB 2.0 is the best for them. But in case if the user wants a USB which is fast and better then the user can opt for USB 3.0. There is a better alternative if one is looking for a super fast speed of transferring data and files.
The alternative has more transfer speed. It is the USB 3.1. The USB 2.0 is quite affordable and normal masses use USB 2.0 because it’s power usage is also moderate.
Since both (USB 2.0 and USB 3.0) are compatible with each other. It is advised to use the USB 2.0 connector for a USB 2.0 drive and it’s the same for the latter.
Many people working in the office opt USB 3.0 because of the super fast transfer of speed and better power it delivers and even provides. The USB 2.0 has one path communication which consumes a lot of time.
Due to the technology making things very easy for the users. People opt for USB 3.0 more. No wonder why it has gained so much popularity after it was created.
Many places the USB 2.0 are all being replaced by USB 3.0. It is only because the USB 3.0 is very advanced and better than the former USB.
Now it depends on the user’s budget and preferences. With all the differences, one can understand how better the USB 3.0 is than the USB 2.0.
Many users these days have also stopped using USB 2.0 and started going for USB 3.0. It is because of the speed and power usage.
Now, it is up to the user depending on their work and convenience whether to choose USB 2.0 and USB 3.0. These decisions are always left up to the user’s choice and budget.
While both have their limitations and benefits regarding price, speed, and many more. One can properly distinguish the USB with the “block” color. The price of the two are also very different.
Choosing the one USB for one’s preference depends on the user and the reason why the user requires it. The choice and requirements depend on the user. Therefore, whether to choose between USB 2.0 or USB 3.0, always depends on the user.
