USB technology has evolved considerably over the years, with each new version bringing with it significant improvements that impact the way we connect and transfer data between devices. In this article, we’ll explore the key differences between USB 4.0 and USB 3.2 , two of the most recent versions of the USB standard.

USB 3.2 was introduced in 2017 and can be considered an evolution, introducing multiple configurations to maximize transfer speeds. This version allows for speeds of up to 20Gbps in optimal configurations, as well as being backwards compatible with previous versions, meaning users can continue to use their older devices without worry. USB 3.2 primarily uses Type-A and Type-C connectors, making it flexible and accessible for most users.
Main Features of USB 3.2
Improved Transfer Speeds: USB 3.2 offers superior performance compared to its predecessors, achieving faster data transfers thanks to its efficient use of available bandwidth.
Multiple Channels: This version can operate on multiple channels at once, meaning it can simultaneously use two 10Gbps channels, thus achieving 20Gbps.
Backward Compatibility: One of the biggest benefits that USB 3.2 offers is the ability to continue working with older devices, providing excellent value to users.
USB 4.0: Revolutionizing Connectivity

On the other hand, USB 4.0 is the most recent version and has come to redefine how connectivity is understood in the field of technology. Launched in 2019, USB 4.0 can reach speeds of up to 40 Gbps , doubling the maximum speed of USB 3.2. It is important to mention that USB 4.0 is also backward compatible with previous versions.
Outstanding Features of USB 4.0
Faster Speed: With its ability to reach up to 40 Gbps, USB 4.0 allows for dramatically faster file transfers, which is critical for users handling large volumes of data.
Transfer Protocols: USB 4.0 combines several transfer protocols, including Thunderbolt 3, allowing for greater flexibility and power in connections.
Exclusive Use of Type-C: Unlike USB 3.2, which uses both Type-A and Type-C connectors, USB 4.0 relies exclusively on the Type-C connector, which is smaller and reversible.
Comparison between USB 4.0 and USB 3.2
When comparing USB 4.0 and USB 3.2, it is essential to consider several key factors that can influence the user's decision:
What is the Real Speed?
While USB 3.2 can offer speeds of up to 20Gbps at its highest setting, USB 4.0 doubles this with speeds of up to 40Gbps. This makes USB 4.0 the preferred choice for those who require extremely fast transfers.
Compatibility and Connectivity
Since both versions are backwards compatible, consumers can rest assured that their investments in older devices will not be rendered obsolete. However, the transition to USB 4.0 will mean a shift to Type-C connectors, which may require adapters for some users.
Cost and Availability
The price of USB 4.0 cables and devices can be higher compared to their USB 3.2 counterparts, due to the more advanced technology and faster speeds. This can influence the purchasing decision, especially for users on a tight budget.
In short, both USB 4.0 and USB 3.2 have their advantages. USB 3.2 remains a solid solution for most users, offering high speed and wide compatibility, while USB 4.0 is positioned as the ideal choice for those looking for maximum performance.
