-USB3.0 x 4 support up to 5Gbps High Speed

USB3.0 to USB 3.0 x4 HUB with an aluminum shield that supports data transfer speeds of up to 5 Gbps is a device that allows you to connect up to four USB devices (such as flash drives, printers, or mice) to a single USB port on your computer or other device. These HUBs typically work by providing additional USB ports that you can use to connect your devices, allowing you to expand the connectivity of your device.

The aluminum shield on this type of HUB is a protective layer that helps to prevent damage to the HUB and its components from physical impacts or other types of external interference. It also helps to dissipate heat and improve overall performance of the HUB.
