To test this USB-C hub, we plugged a 4K display, a Crucial X8 external SSD, and a Logitech Unify dongle into it. Everything is powered by a 100W USB-C charger, with the hub powering our test PC.
Two USB 2.0 ports offer read and write speeds close to 40MB/s, thus in line with the approved standard. These sockets will be used above all to connect a keyboard, mouse or headphone, for example. A little surprise on the other hand regarding the USB 3.0 port: we should usually get around 500MB/s since it’s a port capable of 5Gbit/s. However, the Crucial X8’s speeds are just over 1,000 MB/s read or write, i.e. USB 3.2 Gen2 port speeds of 10 Gbit/s. Surprise, but always nice to take!
Connected to a Philips 4K monitor, the refresh rate does not exceed 30 Hz. 60 Hz is only possible at 1920 x 1080 pixels. Thus, switching to a higher definition will automatically lower the refresh to 30Hz. Suffice it to say that the use of this hub is limited to 1080p screens, and the 30Hz refresh rate on a higher definition screen is particularly unpleasant.
