Part 1: Difference Between USB 3.0 and 2.0

Universal Serial Bus (USB) is a standard that provides an interface to connect your computer with any peripheral device. With a lot of advancements in technology, USB 3.0 has become the new standard for USB devices.

While comparing USB 2.0 and USB 3.0, they vary in size and a handful of other things that distinguish them. This section has gathered the significant differences between USB 3.0 and USB 2.0. Read below to understand the difference.

1. Physical Difference

You may wonder: if there are any physical differences between USB 2.0 and USB 3.0? How to distinguish both of these by their appearance? Well, that's not difficult. Many computers have both USB 2.0 and USB 3.0 ports.

a) Color Difference

The above image displays both USB 2.0 and USB 3.0 ports. The left port is USB 2.0 colored black from inside, while the port on the right is USB 3.0 colored blue from inside.

b) Number of Wire Connections

Another difference between USB 2.0 and USB 3.0 is the number of wires connected. USB 2.0 supports half-duplex communication and has a total of 4 connector wires. Whereas USB 3.0 has a capacity of 9 connector wires. It permits two-way communication simultaneously by having five additional wires due to an increase in its bandwidth.

2. Price

USB 2.0 version is generally less expensive than the USB 3.0 version. You can buy a suitable USB 2.0 device much cheaper. USB 3.0 is comparatively costly for sure since it offers ten times faster transfer speeds. It can even reach more high if you opt for your desired features.

That's up to your choice, but if you frequently transfer huge files, USB 3.0 still be a better choice for you if you can afford it.

3. Speed

Compared to USB 3.0, the data transfer rate of USB 2.0 is prolonged, which is at 480 megabits/s (60MB/s). While USB 3.0 is ten times faster than USB 2.0. Its data transfer rate is up to 4800 Mbps, i.e., 625 Mbs per second.

4. Compatibility

USB 3.0 ports are backward compatible. That is to say, and if you connect a USB 2.0 drive to a USB 3.0 port, the drive will work as expected. USB 3.0 will exhibit the transfer rate similar to USB 2.0 drive would while connecting to a USB 2.0 port.

USB 3.0 devices are also backward compatible means. If you plug a USB 3.0 flash drive into a USB 2.0 port on your PC, it still can be readable. However, the USB 3.0 will work at the speed of the port, no matter it is port 2.0 or 3.0. So, in this case, the superfast transfer rate of USB 3.0 is not fully realized.

5. Power Management

Compared to USB 2.0, USB 3.0 provides more efficient power management and increases power delivery.

USB 2.0 can deliver power up to 500 mA, whereas USB 3.0 caters up to 900 mA. It increases total power delivery from 2.5 W to 4.5 W (5 V). So as far as charging is concerned, USB 3.0 devices can be charged faster.

The USB 3.0 devices deliver power when required and conserve energy when the device is connected but idle. So USB 3.0 is more advanced than USB 2.0 in terms of power management.

Summarizing

Here the question arises, "Which One Should You Choose ?"

Well, now you understand the main differences between both versions. So you can easily opt for one fulfilling your needs reasonably. So far now, the only defect of USB 3.0 is that it is more expensive than USB 2.0.

In terms of USB 2.0 vs. 3.0 from various aspects, USB 3.0 offers the fastest speed, is backward compatible, and offers higher efficiency power management than the old USB 2.0.
