Released in 1996, the USB standard is maintained by the USB Implementers Forum (USB-IF). A broad variety of USB hardware exists of which USB-C is the most recent.

#WHAT IS USB 2 VS USB 3 SERIAL#

Universal Serial Bus (USB) is an industry standard that establishes specifications for cables and connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers.

It is likely that the confusion surrounding the USB3 naming convention will never completely become clear and consistent throughout the market. These are probably USB 3.2 Gen 1x1 devices that were released prior to the USB 3.1/3.2 updates and never had their marketing information revised to match. But to this day, you will see products that are still marketed as “USB 3.0” or “USB 3.1”. Most devices that are USB 3.1 Gen 2, or USB 3.2 Gen 2x1 will be identified as such. With the release of USB 3.2, all previous versions of USB 3 were re-branded under USB 3.2 and given a “Gen XxX” designation to specify generation and number of lanes.

#WHAT IS USB 2 VS USB 3 UPDATE#

Not all USB 3 devices have a USB Type-C connector, and not all devices with USB Type-C are USB 3.īuilding off the improved encoding scheme of SuperSpeed+ introduced in USB 3.1, and an update in the USB Type-C specification that doubled the bandwidth available in USB Type-C cables, USB 3.2 was released capable of reaching data transfer rates up to 20Gbps. Though closely related, USB Type-C is only the specification for the physical cable and connector. It is a common misconception that USB Type-C is the same as USB 3. USB Type-C solved this by introducing an oval-shaped connector which could be connected in either direction. Prior to the release of USB Type-C, one of the biggest annoyances with USB cables was that they could only be plugged-in in one direction. USB Type-C (or USB-C) was also released during this time period. However not all companies were quick to update their marketing information and advertisements to reflect this change, and the name “USB 3.0” continued to be used synonymously with “USB 3.1 Gen 1”.

In order to maintain consistency with the previous spec, “USB 3.0” was updated to “USB 3.1 Gen 1” with the newest version called “USB 3.1 Gen 2”. The USB 3.1 update improved the encoding scheme to reduce overhead which lead to a better data transfer rate, up to 10Gbps over as single lane, a transfer mode called “SuperSpeed+”. When USB 3.0 was first released, its main feature was a fast transfer mode called “SuperSpeed USB” which was able to reach transfer speeds of up to 5Gbps, 10 times faster than what the previous USB 2.0 spec was capable of.įor several years there would exist only one version of USB3, USB 3.0.Ģ013 - 2016 : USB 3.1 SuperSpeed+ and USB Type-CĪ few years after the introduction of USB 3.0 the USB Implementers Forum announced the first update to the specification, USB 3.1.

In this article we will provide a timeline of USB3’s development history, which will hopefully help explain how USB 3.0 evolved to USB 3.1 and then to USB 3.2. This continual rebranding has led to plenty of confusion over the USB3 naming convention. These improvements were rolled out across two updates, with each update leading to a rebrand. Unlike USB 2.0, which retained the same version and data transfer rate throughout its lifecycle, improvements made over the past decade to USB3 has led to faster transfer rates. Originally debuting in the 2010’s as “USB 3.0 SuperSpeed USB”, the USB3 interface has proven highly successful and has become as ubiquitous as its 2.0 predecessor.
