what peripherals should i connect to usb 2 vs usb 3

The most recent update is the USB 3.2 Gen 2x2 protocol, which uses two lanes of double-speed data traffic to top out at 20Gbps.Ĭonfusing matters more, the USB 3.2 single-lane protocols are basically renamed USB 3.1 protocols, which you may still see on some devices.

Either way, the result is 10Gbps peak throughput.

The next step up in speed bifurcates into two alternatives: the use of double speed lanes of data that abide by the old speed limit ( USB 3.2 Gen 1x2) or a single lane that operates at twice the speed ( USB 3.2 Gen 2x1).

It allows a maximum throughput of 5Gbps to travel over a single lane of data and can use an old-school Type-A rectangular plug or the oblong USB-C connector.

Today, the most popular USB spec is the USB 3.2 Gen 1 protocol.

Here is a breakdown of the specifications: The four main USB protocols in use today are confusing, to say the least, creating an alphabet soup of standards that could muddle the most technical among us. USB-C is just the connector type it’s built on the Universal Serial Bus specification, and that’s where things get messy. And it’s closely linked to several powerful new technologies, including Thunderbolt and USB Power Delivery, that have the potential to change how we think about our gear and how we work in the office, on the road, and at home. But USB-C continues to evolve toward faster data transfers and the ability to push more power to devices.

Its symmetrical design means it can be inserted either way - up or down - eliminating many of the frustrations of earlier USB ports and putting it on a par with Apple’s reversible Lightning plug.

USB Type-C, commonly referred to as USB-C, is becoming the standard connector for moving data and power to and from a wide variety of computing devices. The USB-C port (second from left) is gradually replacing older USB-A ports (third and fourth from left) on laptops and other devices.
