Since Kingston’s HyperX Max 3.0 got high marks in our previous USB 3.0 roundup, we’re using four of them to simultaneously tax the bandwidth of each controller as much as possible (obviously we can only connect up to two drives to each controller, so the four SSDs have to be deployed across a combination of ports to tax the various controllers). This should provide a worst-case scenario, since solid-state-based USB 3.0 storage solutions deliver much more potential throughput than the conventional external drives out there.

The USB 2.0 and 3.0 standards do not include support for native command queuing, so we’re only testing at a queue depth of one.
