We used bus-powered peripherals to test each hub: an SSD, a hard drive, and a rewriteable DVD drive, all to make sure enough power was being delivered. We also ran speed tests on those hubs with ethernet connections, just to detect any anomalous results. We performed spot checks with other peripherals.
We conducted standardized tests to transfer a file from the SSD to the laptop; from the hard drive to the SSD; and then from an SD card to the PC, while simultaneously transferring files from the hard drive to the SSD. In some cases we used AJA’s System Tool app to run read and write tests on connected drives. In almost all cases, the performance was identical, with a spread of about 3 percent—good news for you, as that’s one less thing to worry about.
We measured the surface temperature while these tests were run. You’ll see some buyers on Amazon pages complaining about how hot a hub gets; some do get on the warmer side. Also, where we could, we measured the power input for each hub.
We looked at how SD cards were inserted—you’d be surprised how many don’t work unless they’re inserted upside down!
We also noted the cord length, as shorter cables limit your options when positioning the hub around your laptop or tablet. Worst case, a short cable causes a hub to dangle from a tablet whose USB-C port is mounted toward the top.
After testing our USB-C hubs, we can confirm that some no-names perform just as well as their more well-known counterparts, and for less money, too. One thing to keep in mind: Because price is so critical to our recommendations, know that some of the prices may change as manufacturers offer sales. Therefore some hubs we didn’t recommend primarily based on price could become more purchase-worthy.
