I hope that clarifies any confusion you might have had in regards to USB 2.0, USB 3.0 and Thunderbolt audio interfaces. Speed: USB 3.0 maximum speed is 4.8 Gbit/s USB 3.0 increased the USB 2.0 max data rate ten-fold to 4.8 Gbit/s (or 600 mega bytes per second). Simultaneous up/down transfer is a huge new improvement for USB 3.0. Just use whatever you have access to and what works with your budget! Any USB-C external drive that supports USB 3-2 2×2 will therefore claim to offer up to 2000 MB/s read/write speed but thats only true if your computer. This is new for USB, since with USB 2.0 the 2 data transferring lines could only transfer data up or down at any given time. Remember, if you’re going to be running HUNDREDS of audio inputs/outputs, you could benefit from a data transfer protocol that provides more stability.įor most of us though, it’s really not necessary. Why do manufacturers still make USB 3.0 and Thunderbolt audio interfaces though? That’s what you get when you’re working with the best audio drivers in the industry! That’s why performance is consistent on all RME audio interfaces (USB, Thunderbolt, etc…). First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer. So, it doesn’t matter which data transfer protocol your audio interface uses… If the audio driver was poorly written, your audio interface won’t perform at its best. When comparing 2.0 and 3.0 there are a few major differences. This makes it more than 20 times faster than USB 2.0 and twice as fast as USB 3.0. As for USB 3.0, it is approximately 10 times faster than USB 2.0 with its data transfer rate up to 5 Gbit/s (625MB/S). USB 3.1 Type-C delivers a 10Gbps data transfer rate. What’s the #1 cause of all audio latency issues? It’s the AUDIO DRIVER! Although it is a bit slow for data transfer, for connecting peripherals such as keyboards, mice or headsets and the similar, the speed is sufficient. Summary: USB 2.0 vs USB 3.0 Audio Interfaces
