USB4 USB has evolved through a series of standards (see Table 1) that specify how cables connect, communicate and supply power to computers, mobile devices and peripherals. The latest iteration is USB4 and, like previous versions, it represents another leap forward in data transfer speed, video resolution and power.
USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps). … Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or . . . Read more
Speed, power, and video delivery A USB-C port equipped with Thunderbolt 3 can push data speeds to a theoretical limit of 40Gbps. To show how far we’ve come, that’s four times faster than USB 3.1 and more than 3,000 times faster than the original USB 1 spec of 12Mbps.
It was a big improvement from USB 2.0 which first arrived in 2000 with transfer speeds of only 480 Mbit/s. Since then, we’ve moved on from USB 3.0 which is now known as USB 3.1 Gen 1. Therefore, USB 3.0 is the same thing as USB 3.1 Gen 1.
USB Type-C is NOT the same thing as USB 3.2. USB Type-C ONLY describes the physical connector. USB 3.2 ONLY describes the actual capabilities of the port.
USB 3.1 Type-C delivers a 10Gbps data transfer rate. This makes it more than 20 times faster than USB 2.0 and twice as fast as USB 3.0. It is also faster than the 6.0Gbps rate of the SATA III standard, allowing external hard drives to exceed the current speed of . . . Read more
July 2013 In This Post… Release Name Release Date Mode USB 1.1 January 1998 Fixed common issues of USB 1.0. Data rates remained the same. USB 2.0 April 2000 High Speed, also Hi-Speed USB 3.0* November 2008 SuperSpeed USB 3.1 Gen 2 July 2013 SuperSpeed+
USB 3.0 provides better speed and more efficient power management than USB 2.0. USB 3.0 is backward compatible with USB 2.0 devices; however, data transfer speeds are limited to USB 2.0 levels when these devices inter-operate.
Most USB-C ports are built on the second-generation USB 3.1 data-transfer standard, which can theoretically deliver data at speeds of up to 10Gbps — twice as fast as USB 3.0 and first-gen USB 3.1, which both top out at 5Gbps. … To make sure the data gets through at higher . . . Read more
Again, while USB Type-C and USB 3.1 and USB 3.2 are sometimes referred to interchangeably, they are not one in the same. Both USB Type-A and USB Type-C connectors are used to facilitate USB 3.2 Gen 1 and Gen 2 connections, and USB C is also used to facilitate the . . . Read more
