TL;DR: A USB 3.2 Gen 2 hub provides one 10Gbps upstream link, not 10Gbps of dedicated bandwidth for every port. Real performance depends on the host, cables, hub controller, peripherals, power, and operating system.
A USB 3.2 Gen 2 hub provides a 10Gbps signaling link to its host. It does not provide 10Gbps of independent bandwidth to every downstream port. One fast external SSD can consume most of that link; two busy SSDs must share it. The hub should also work on 5Gbps USB, USB 2.0, USB4, and Thunderbolt 3 or 4 hosts, but the connection falls to the fastest mode supported by every component in the path.
That last condition causes most surprises. The laptop port, upstream cable, hub controller, downstream cable, and peripheral all have a vote. A USB-C connector alone guarantees none of the data rate, charging, or display features buyers often associate with it.
Read "10Gbps" as a link rate, not a file-copy promise
USB 3.2 Gen 2 is the 10Gbps mode also called Gen 2x1. USB 3.2 Gen 2x2 is a different, two-lane 20Gbps mode. The USB Implementers Forum now recommends the consumer-facing name USB 10Gbps, which is clearer than the generation label. For procurement, require the numeric rate on the data sheet and purchase order.
