Type-B connectors are typically used for devices such as printers. The Type-B connector is much more square in appearance, with the top two corners angled for USB 2.0.

The USB 2.0 connector has 4 connector pins, the USB 3.0 version increases this to 9, allowing faster speeds but supporting full compatibility. It’s typically used for devices such as USB memory sticks, cable-to-socket connectors and data transfer cables. The Type-A connector is the standard rectangular one that everyone should recognize when they see a ‘USB stick’. Other advantages include the reduced number of connector standards and backwards compatibility. USB 2.0 was able to transmit data at a maximum speed of 480Mb/s while the USB 3.0 connectors can reach speeds of up to 5Gb/s. The primary advantage (and difference) of USB 3.0 over USB 2.0 is the increased speed. USB 3.0 simplifies this down to three connectors that are all backwards compatible with their previous counterparts. So while USB-C is objectively better than USB-A, USB-A still has its place in the computing world and should be around for several years to come.USB 2.0 (the kind you’re most likely using for devices older than a few years) specifies six standard connectors A, B, and then both a Mini and Micro version of each. Also, USB-A designed for USB 3.0 is still plenty sufficient for everyday computing and even transferring large photos or videos, if you don't mind investing the time. After all, an external HDD or SSD with a USB-A connection won’t do you any good if you can’t connect it via USB-C.

Machines lacking USB-A ports, such as the new MacBook Pro 14-inch and Dell XPS 13 Plus, can put you at a disadvantage if you don’t have an adapter. There are millions of devices that still use USB-A ports. In some cases, you may need it over USB-C. With that said, USB-A isn’t completely useless. This is why it is becoming the industry standard and will become ubiquitous in the near future. USB-C is undeniably the superior connection type due to its higher data transfer rates, ability to charge large electronics and symmetrical connection port. However, the most recent USB 4.0 spec can reach up to 40Gbps and is only available in USB-C form. rectangular) and a USB specification which reveals how capable it is. However, USB 3.2 has two 10Gbps lanes and is thus capable of achieving 20Gpbs.īoth USB-A and USB-C ports can support USB 2.0 to 3.2, which makes the whole thing a bit confusing since a USB port has both a connector type (USB-C vs. USB 3.0 can achieve transmission speeds of up to 5 Gigabits per second (or 5 Gbps), whereas USB 3.1 can achieve up to 10 Gbps. Most of us will never care enough to tell the difference between USB 3.0 and USB 3.2, but it's nice to know how it all works. Put simply, the more advanced versions of the USB protocol allow for faster data and power transfer. In general, the higher the number the better, and you should be able to tell what version(s) your USB device supports by looking at the packaging and/or manual.
USB 3.0 (aka USB 3.1), 3.2 and 4.0 are USB data protocols for USB connections and refer to the data formats the port can handle.
USB-C is also compatible with Thunderbolt 3 and Thunderbolt 4, which is why you'll often see laptops and desktops with combo USB-C/Thunderbolt 4 ports - the port supports either cable. SuperSpeed and SuperSpeed+ support (through USB 3.0 and higher) allows for faster data transfer speeds. Support for Power Delivery lets you charge large electronics like laptops via USB-C. With an adaptor, USB-C is backward compatible with USB-A and with various connection types, including HDMI. Because of the connector’s symmetrical design, you don’t need to worry about which way you insert the cable into a port (thank goodness). USB-C ports are smaller and thinner than USB-A. It also has many features that surpass its predecessor. This is because the connection type fixes many of the problems associated with USB-A. Almost every new laptop, tablet or phone has USB-C connectivity.
USB-C (or USB Type-C) is slowly becoming the standard port for consumer devices.
