USB 2.0 vs. 3.0:
USB 2.0 Port:
The USB 2.0 port is known as “Hi-Speed USB,” which was first established in the year 2000.
USB 2.0 has at least six different port types, including Type-A, Type-B, Micro-A, Micro-B, Mini-A and Mini-B.
This connection technology has higher support than the USB 3.0 standard among USB-enabled devices.
Devices that support 2.0 are typically less expensive with flash drives being a good illustration.
A single USB 2.0 flash drive can be purchased for 750Rs or less.
USB 2.0 devices and cables can be used with newer 3.0 devices and cables, but don’t assume 2.0 device speeds to equal 3.0 device speeds.
As it can transfer data at 480 Mbps which is much less than the maximum speed of a USB 3.0 device.
The USB 2.0 devices are less efficient in power management resulting in a longer charging time.

Advantages of USB 2.0:
- They are aided by a greater number of devices and cables.
- Flash drives are less expensive to purchase.
- And the 3.0 devices and cables are physically compatible.
Disadvantages of USB 2.0:
- Data transfer rates are much slower than USB 3.0.
- Power management is inefficient.
- It cannot attain 3.0 speeds even while using 3.0 devices.

USB 3.0 Port:
USB 3.0 is currently supported in a few devices.
In 2008, the USB 3.0 port commonly known as “Superspeed USB” was released.
With a maximum transmission speed of 5,120 Mbps, USB 3.0 is significantly quicker than USB 2.0.
The devices that support USB 3.0 are newer, higher-end, and more expensive.
The pricing difference between 2.0 and 3.0 flash drives can limit storage capacity whereas 3.0 flash drives can speed up data transfer.
Moreover, they are often more energy-efficient and charge faster than USB 2.0 devices.
More power-hungry equipment can also be connected to the 3.0 port.
Although USB 3.0 is technically compatible with 2.0 devices, you will not be able to achieve 3.0 speeds and will have to settle for a maximum speed of 2.0.
Type-A, Type-B, Micro-A, and Micro-B are the four-port found in USB 3.0.
