USB 2.0 vs. 3.0 What’s the Difference and Which One Is Better?

Peripheral devices are supposed to be known for their data transmission speed and quick service, and that is valid for a reason. Besides, for USBs the USB 2.0 and 3.0 are one of the common types or versions you will come across with.

usb 2.0 vs usb 3.0

Actually, the universal serial bus ensures lag-free and ever so strong connectivity between PCs and devices. Apart from USB 2.0 and 3.0 there is another version with 1.0, however, the previous ones are most in use.

Of recent times, you’ll mostly come across with the USB 2.0 in many computers, and other tech gears featuring ports. Certainly it implies its importance followed by the ground-breaking performance.

But do you really know the difference between them? If not, keep reading this article, you’ll get to know which one you should go for!

What is USB 2.0?

USB 2.0 is also known as hi-speed USB. It makes sure to support data that offer the user the maximum speed of 480 Mbps. As said before, USB 2.0 is just another version of its predecessor 1.1. USB 2.0 is better for small files and documents only.

What is USB 3.0?

USB 3.0 is best known as Super Speed USB mainly for its performance. A USB port with 3.0 makes sure the premium speed and high-end effective performance for data travel, especially when you are comparing.

In addition to that, the efficient power management of USB 3.0 is a plus point. All in all USB 3.0 port makes sure of the more advanced-level data transmission along with the satisfactory performance.

Difference in 2.0 and 3.0

Although 2.0 and 3.0 are the speed and performance measures of the USBs, there are still apparent differences between the two.

usb 2.0 vs 3.0

It’s a good sign when you don’t know the actual diversion, but still from the very first sight you can tell what USB you have.

Usually the USB port with 2.0 has the white or black ‘block’ inside the USB port, while the USB with 3.0 ports have the blue block within the USB port.

However, if you have the advanced USB 3.1 port, it will feature the red block inside. Aside from the coloration of USB ports, the number of wire connections available is another difference you can see.  The 2.0 USB will have a total 4 connector wires, conversely, the USB 3.0 are made with the 9 connector wire.

Hence it has become evident of offering you enhanced speed while increasing the bandwidth with USB 3.0. Moreover, 3.0 USB built also offers the user with the two-way communication at a single time, which is pretty appreciable.

Compatibility Approach of USB 2.0 and 3.0 Ports

If you insert the flash drive of USB 2.0 into a 3.0 port of your pc or laptop, it’ll still work perfectly, which means the port with 3.0 approach is backward-compatible.

On the other hand, if you insert the USB pen drive featuring 3.0 speed into a port that is 2.0, it can read the data, but the speed will rather have an effect. This is because the drive will work on the speed of ports and not the flash drive, and the speed of data transfer will be lesser than the above-mentioned case!


Price is an obvious thing when you want to purchase anything. Since USB 2.0 is not that much faster and faster as compared to the USB 3.0 hence they are quite cheaper while USB 3.0 versions are extravagant in terms of the cost.

Which One Is Better?

Certainly, the USB 3.0 version has more powerful and robust output. Besides, the above-mentioned points seconds the very thought as well.

In addition to that, USB 3.0 verifies a maximum rate of 5 gigabits per second which is why it has got way powerful and fastest output. USB 2.0 is actually very sluggish, that’s why many of the users do not prefer it in the first place. It offers you the 10 times swift approach in comparison with the 2.0.

If you are running low on budget or you want to transfer only a smaller size file, the 2.0 version of USB is better, otherwise, never compromise on the fastest and advance-level data travel means such as USB 3.0!

Data Transfer Rate

Data transfer rate of bandwidth is an important factor especially when we talk about the USB and its ultimate performance. Like we know, the 3.0 version holds more accuracy due to its in-built capabilities, but what is the data transfer rate in the universal serial bus?

2.0 vs 3.0 data transfer rate

USB 2.0 aptly transfers 480 megabits each second, whereas the 3.0 USB would have the speed of 4,800 Mbps. Hence it is clear that the data transfer of USB 3.0 is much faster, approximately 10 times faster than that of its previous version.

However, with USB 3.1 things have changed pretty much drastically. You get to have a data transfer rate of 10,000 Mbps, therefore, it becomes twice as fast as USB 3.0.

Power Consumption In Terms Of Each USB

Power consumption of USB differs and varies from its version to version! Yes that is true because the internal build and the number of wires readily decides how much power it needs. Before opting for either USB 3.0, 2.0 or 3.1 it’s important to know its approach.

  • USB 2.0 is able to provide up to 500mA power or 0.5A, it needs 15 watt.
  • USB 3.0 is capable of providing up to 900 mA or 0.9A current, it needs 4.5 watts.

USB type C Connector

USB type c is something that you definitely have heard of. If you are planning to make a purchase of USB, knowing about its ports and Type C connection is something that will prove to be helpful.

Basically, USB type C is a connector with 24-pin. It is a rotationally symmetrical connector. However, it is not any USB standard. The Type-C is the device at the end of the cable which ensures the power and speed capacity. Besides, the wire at USB type-C connectors can support the Gen 2 feature without any hindrance.

How to get maximum throughput in?

Peripheral devices certainly add the ease of swift data travel; therefore, to get the most out of USB becomes the utmost thing to know about.  If you are wondering on whether or not you can attain the total USB 3.0 super speed or not i.e. 4.8Gbps you need to have:

  • The USB 3.0 port in PC or laptop features PCIe 2.0/2.1 or EC 2.0 slots.
  • A USB cable to connect the external USB 3.0 device to the same port i.e. 3.0.
  • A de drive, card reader, or a camera that goes in support with the USB 3.0.
