It should be noted, however, that while the data transfer rates of USB 3.2 Gen 2 and Gen 2×2 are impressive, many devices aren’t yet capable of reading or writing at those speeds. USB 3.0 Type-A (left) and USB 3.0 Type-C (right) It is often identified as USB 4 with a space.) (Note that the correct specification name is USB4 as defined by the USB developers.
It leverages the Thunderbolt 3 protocol and offers transfer speeds of 40 Gbps. USB 3.2 Gen 2×2, released in September 2017, is available only for USB Type-C connectors using two-lane operation.USB 3.2 Gen 2, released in July 2013, used to be called USB 3.1 and offers a transfer rate of 10 Gbps over the existing USB-A and USB-C connectors – twice the rate of USB 3.2 Gen 1.USB 3.2 Gen 1 used to be called USB 3.0 and offers a transfer rate of 5 Gbps, which is about 10 times faster than the USB 2.0 standard.What is the difference between USB 3.2 Gen 1 vs Gen 2 and USB 3.2 Gen 2×2? What about USB4? L et’s break it down: USB 3.0, 3.1 and 3.2 are a little more confusing. The USB 1.0 specification (introduced in 1996) offered a maximum data transfer rate of 12 Mbps (Megabits per second). The standards that dictate the performance of USB are instead expressed as a numerical value, like USB 2.0, 3.1, 3.2 or 4.
It’s important to make the distinction between a given USB port form factor (like Type-A or Type-C) and the data transfer rates and power delivery available over that port. Medium electronics, such as laptops, have until 2026 to implement USB-C for charging. The first stage applies to small electronics like cell phones, digital cameras, and more. This new law is a part of a broader EU effort to make products more sustainable, to reduce electronic waste, and make consumers’ lives easier. It’s also important to note that the USB Type-C charging port will be mandated in the EU starting in 2024.

On the other hand, the industrial PC (IPC) market is just beginning to dabble with integrating USB Type-C ports into the latest generation of commercial devices.įinally, we should note that while USB Type-A and USB Type-B have traditionally been written using the word “type” as shown, USB Type-C is increasingly being written as simply USB-C. USB Type-C ports are becoming more and more common on mobile devices and consumer hardware. This newest USB connector is intended to replace the other existing USB form factors and provide a future-proof, fully-featured option for hardware designers to standardize on. This eliminates one of the most common complaints about USB Type-A. The USB Type-C connector is smaller than both Type-A and Type-B, oval-shaped, symmetrical, and reversible, meaning there is no “wrong way” to plug it in. (The USB Type-C connector shouldn’t be confused with the USB 3.1 or USB 3.2 standards.).
Type-C refers to the physical shape of the newest USB connector. The Mini-B and Micro-B connectors, like their Type-A counterparts, are found on a wide range of electronics, from tablets and handheld GPS devices to cell phones. USB Type-B connectors are frequently used on printers, though they can also be found on some monitors and USB hubs. The more square shaped USB Type-B is somewhat less common but is electrically identical to USB Type-A connectors. This requires them to be oriented properly in order to be plugged in. Gaining popularity in the mid 90’s, standard USB Type-A connectors are rectangular and have a distinct top and bottom. It is also used on many other devices, including those that utilize its Mini-A and Micro-A variants (see image above). The most common and familiar USB connector shape is USB Type-A, which is currently used on the vast majority of computer equipment and peripherals.
