Digital Camera World Verdict

CalDigit’s TS4 Thunderbolt Station 4 is the king of all Thunderbolt docks. It handles peripheral connection, device charging, and display extension like an absolute pro. Alongside the usual set of USB ports it also supports SD Card and Micro SD cards for creatives working with these media formats. The build quality is also second to none with a solid metal case that is probably more solid than it needs to be. With 18 ports you can connect pretty much anything you need to it.
