What’s more, Thunderbolt can handle video files using the same cord. It’s easy to see that the Thunderbolt standard is faster and more efficient than the USB. In addition, the Thunderbolt 3 can signal data and transfer power to connected devices. Thunderbolt 2 doubled that, and Thunderbolt 3 doubled that again to 40 Gb/s. The original Thunderbolt supported up to 10 Gb/s, just like the USB 3.1 Gen 1. The Thunderbolt protocol brought super speed data transfer to the world. (Thunderbolt was formerly known as Light Peak.) It has been the standard-issue on the MacBook since 2011. Thunderbolt is a high-speed peripheral interface developed by Intel and Apple. What’s the difference between USB 4 and earlier bus? The USB 4 follows the Thunderbolt 3 protocol. So, when the USB 4 came out in 2019, it also used the USB-C port shape.

The USB-C interface is used by both Mac and PC and most peripherals on the market today. Additionally, the USB-C transfers data and powers devices. But Apple is now on the line to transition all of its other devices from the Lightning charging port to the USB-C.Īside from the USB-C connector being reversible (you can plug it in any way you like, and it fits the port), it’s also smaller with a more robust data signal. That year, the MacBook model sported a USB-C connector as its only interface (using it for both battery charging and data transfer). It’s worth mentioning that Apple made this move back in 2015. The law effectively unbundles the sale of digital devices from chargers in Europe. In 2021, the European Parliament’s Committee on Internal Market and Consumer Protection proposed that the USB-C would be the standard for all devices-mobile phones, digital cameras, tablets, gaming controllers, and computers. The USB-C will soon be the only interface for data or power connection accepted for digital devices in European Union countries. In recognition of the dizzying array of options for connecting all of our digital devices and peripherals, the USB interface that is becoming the most common is the USB-C.
Both work with USB-C ports, but the USB 3.2 Gen 2 also plugs into USB-A and MicroUSB ports. Things get even trickier with USB 3.2 Gen 1 and USB 3.2 Gen 2. Depending on the device, you may need a USB-A, USB-C, or MicroUSB adapter to connect.
The USB 3.1 is backward compatible with USB 2 and USB 1 (at slower speeds). Next in line, the USB 3 sports a lightning bolt symbol indicating its super speed. And, a new port means that we need a new adapter.įor example, the USB 2 used mini and micro connectors to sync with non-Apple mobile phones, and you’ll find them on flash drives, webcams, and printers. Thankfully, USB is backward compatible, so your faster bus will still connect (though it may limit transfer speeds, so it’s best to use the fastest device your computer can support).įaster data transfer speeds are great, but with every new USB interface iteration, there’s a new port shape. In practical terms, though, most hard drives work much slower than the latest USB versions.
Each new version featured a higher data transfer speed: USB has been through a number of revisions over the years to be compatible with smaller devices. USB connects everything from external hard drives to keyboards, game controllers, network adapters, and more. USB comes in many different size variants, but you’ll most likely find it on your computer in that familiar rectangular port. It’s been a standard on most Macs and PCs since the late 1990s and has been updated several times since then.

Universal Serial Bus (USB) is the most common peripheral interface used to link one device to another and connect to a power source. We’ll tackle the two most common peripheral devices today-the USB-C and Thunderbolt 3.Īre you unsure what the differences between interfaces are and how they affect your backup plans? This installment of “What’s the Diff” is here to help! What Is USB? Some of these ports and interfaces look alike, but they perform differently. How many different adapters do you use to connect your computer to peripheral devices? There’s USB 3, USB-A, USB-C, HDMI… I could go on. This post has been updated since it was originally published in March of 2019.
