Key Points:
- USB-A was invented in 1996 as the first connection designed to link peripheral electronic devices and power to computers.
- USB was designed to standardize connections worldwide and was successful.
- USB-C is a new and improved version that has 24 connector pins which give it significantly greater abilities compared to the 4-pin connector of the “out-of-date” USB-A.
- Most drives, ports, and cables are some version of USB-A. They’ve been around longer and they hold the lion’s share of the public space. However, eventually USB-C will be the standard.
Universal Serial Bus or USB connections have been used to link peripheral electronic devices and power to computers since 1996. It was designed to standardize these connections worldwide, and it was wildly successful. USB-A was the original version. It steadily evolved, over time, into different versions of itself. The similarities and differences of these changes are nuanced and subtle. Basically, it was a steady progression of a standard piece of technology. The purpose of a USB connection always remained the same. It was just the capabilities of the technology that continued to grow.

USB C is newer, faster, and better in almost every way. USB A is much more widely found in general, so it’s easier to use simply due to how ubiquitous it is. USB-C is going to become the worldwide standard. It just might take some time for that to happen. USB-A is the connector that most people are familiar with. It is a rectangular plug and slot with one functional direction. A USB-C is smaller and looks like an elongated oval. It has the benefit of being able to connect on either side. USB-C also has 24 connector pins which give it significantly greater abilities compared to the 4-pin connector of the “out-of-date” USB-A.

Choosing between USB-C and USB-A depends on the specific situation to a certain degree. You don’t need to make a pros and cons list, because it’s mostly a question of personal requirements for a specific task and availability. Ideally, everyone would use USB-C. Every device would be USB-C and every cable would be USB-C. Unfortunately, that’s not the world we live in.
Most drives, ports, and cables are some version of USB-A. They’ve been around longer and they hold the lion’s share of the public space. It’s necessary to be adaptable and realistic. You can’t walk around with a USB-C cable and expect to connect to all of the random devices that you encounter. The vast majority of them will be USB-A. You won’t be able to transfer data, and charging is most likely out of the question. It doesn’t matter how superior USB-C is compared to USB-A if you can’t take advantage of those benefits. USB-C connections are becoming more common. They’re stronger, faster, and more versatile. But they’re still far from the norm.
“Availability of use” needs to be taken into account when choosing between USB-C and USB-A. Anything new or from the past few years will have a USB-C connection. Anything older than that will only have a decreasingly capable version of USB-A. That’s literally billions of devices worldwide that can’t connect using USB-C. That’s why the choice depends on the situation. Use USB-C when you can, but you’ll regularly be forced to use USB-A.

USB A vs USB C: Key Differences
There are two key differences between USB-A and USB-C. The first difference is the strength of the connection. There is a world of difference between the weakest USB-A and the strongest USB-C. There’s a pretty steady gradation between the two. This means that there are certain tasks that suddenly become possible once a certain threshold is reached. The highest quality USB-A cables can keep up with USB-C until about the 20Gbps point. After that, the USB-C stands “head and shoulders” above USB-A.

The second key difference is the market use. USB-C was only introduced a few years ago, and it has yet to fully engulf the landscape. It’s more effective in every way compared to USB-A, but it still has yet to replace the billions of devices that only use USB-A. Only the most recent generation of devices have come with USB-C standards. It will still take quite a few years until USB-A fades away.
Our Hands-On Experience
I’ve been using USB connections since 1996, just like everybody else. We’ve all faced the frustration of plugging in an upside-down USB-A cord. They got the job done though, and they would progressively get better over time. We didn’t really have anything to compare it to, and it was fine for what it was. Then the USB-C came out in 2017 and eliminated the problems of the past. It would plug in either direction, it could more than double the throughput, and it even came with alternate operating modes. It’s clearly the way of the future, it just looks like it will be a few more years until it more thoroughly overtakes USB-A.
Winner: USB C

USB C is the clear winner. This isn’t really a discussion about overall pros and cons. It comes down to the availability of a superior form of the same technology. It doesn’t come down to preference or style. It comes down to the endless march of progress. People are welcome to stick with USB-A as long as they can, but they will all eventually make the switch.
