USB Basics

Standard large rectangular USB connectors are known as Type-A connectors. They are available in white for USB 2.0 and blue for USB 3.2 There are different versions of USB 2.0 connectors, including Mini, Micro and Lightning.

In addition to these connectors, the Type-C connector can be plugged in either way round and is compatible with both USB 2.0 and USB 3.2 devices. It is also compatible with the USB Power Delivery (PD) specification and can be used to charge mobile devices including laptops and Chromebooks.

USB 2.0

Up to 480Mbps data transfer speed.

USB 2.0 is also known as Hi-Speed USB and theoretically can achieve data transfer speeds of 480Mbps (480 million bits per second).

USB 3.2

Up to 5Gbps data transfer speed.

USB 3.2, known as Super-Speed, is divided into two categories, Gen 1 and Gen 2.

  • Up to 10 ten times faster than USB 2.0
  • Backwards compatible to USB 2.0   
  • Gen 1 gives 5 Gbps (5,000 million bits per second). All our current USB 3.2 devices are compliant with Gen 1 specification
  • Gen 2, known as Super-Speed-Plus, is a higher-speed version providing 10 Gbps (by using a more efficient data encoding process).
  • Both Gen 1 and Gen 2 are backwardly compatible with USB 2.0 devices and
    Gen 2 is backwardly compatible with Gen 1
  • USB 3.2 is now available only using the Type-C connector
  • USB 3.2 Gen 1x1 is same as USB 3.1 Gen 1 (5 Gbps)
  • USB 3.2 Gen 1x2 and Gen 2x1 both provide 10 Gbps (although they use different encoding)
  • USB 3.2 Gen 2x2 provides 20 Gbps

Type-C

Singularly versatile.

The USB-C port puts everything you need in a port all in one place. It provides charging, speedy USB data transfer (up to 5 Gbps), and video output in a reversible design that’s one-third the size of a USB 3.2 port, giving you the flexibility to easily connect your favourite devices.

The Type-C connector can be plugged in either way round and is compatible with both USB 2.0 and USB 3.2 devices. It is also compatible with the USB Power Delivery (PD) specification and can be used to charge mobile devices including laptops and Chromebooks.

Thunderbolt

Thunderbolt 2 and Thunderbolt 3 do not share a common connector type. This not only causes confusion but can also add cost to a solution should TB2-TB3 adaptors be required.

Thunderbolt 2 was used extensively on older Apple MacBook computers and the Apple MacMini (as of mid-2018). Thunderbolt 3 uses a USB Type-C connector.

Thunderbolt 2

  • The two Thunderbolt 2 ports feature dual 20Gbps channels for data transfer.
  • That’s up to four times faster than USB 3.2 (Gen 1).

Thunderbolt 3

  • The two Thunderbolt 2 ports feature dual 32-Gbps channels available for data transfer (8Gbps for video).
  • Two times faster than Thunderbolt 2
  • Eight times faster than USB 3.2
  • That’s up to four times faster than USB 3.2 (Gen 1).
  • 62 times faster than USB 2.0
