USB 1.1 vs 2.0 transfer Speeds

We are often asked the difference between USB 1.1 and USB 2.0. Essentially the difference is the speed. The theoretical limits of USB 1.1 is 12 Mbps (Mega bits per second) and USB 2.0 is 480 Mbps

In practice, nothing actualy runs at the theoretical limits, and there can be many things that can cause a bottleneck. Our Fastlynx file transfer program has a benchmark function that will let you test the speed and reliability of your connection.

Both USB 1.1 and 2.0 were reliable…I didn’t lose any packets.

USB 1.1 bridge cable gave an actual throughput of 6.9 Mbps
USB 2.0 bridge cable gave an acutal throughput of 187 Mbps
