I recently purchased several USB hubs advertised as supporting 10 Gbps speeds and decided to test their actual performance.

Abstract: I bought some USB hubs that declare 10 Gbps and wanted to test them. In my experience, USB-related equipment often fails to deliver the advertised speeds, leading to slower-than-expected data transfers.

1 Purchasing Auxiliary USB Devices

Most modern computer peripherals rely on USB communication. However, in the past, many USB devices failed to meet their advertised speeds. This has occasionally impacted my workflow—for instance, having to wait 20–30 minutes just to copy a backup database to a USB flash drive.

I bought some new USB gadgets and wanted to perform some simple load tests in real-world scenarios, like writing to an external disk.

2 Benchmark – External SSD without USB Hub

To get a baseline throughput value, I tested the External SSD disk without intermediary devices. Here are my baseline tests:

3 Testing USB-Hub 4-in-1

Here is the gadget description and throughput test results:

So, it looks like it actually delivers close to 10 Gbps (1026 Mbps ~ 8.2 Gbps).

4 Testing USB-Hub 7-port

Here is the gadget description and throughput test results:

So, it looks like it actually delivers close to 10 Gbps (1053 Mbps ~ 8.4 Gbps).

5 Testing Adapter USB-A -> USB-C

Here is the gadget description and throughput test results:

So, it looks like it actually delivers close to 5 Gbps (464 Mbps ~ 3.7 Gbps).

4 Conclusion

This time, I was lucky; the devices I bought delivered speeds close to the declared specification.
