Reviewed: OWC Mercury Elite Pro Dock Storage Solution with USB-A Ports, DisplayPort, Gigabit Ethernet, Thunderbolt 3
Configurations up to 32TB (2 X 16TB). MPG tested the 24TB model incorporating dual Toshiba 12TB MG07ACA12TE drives which are very high performance hard drives.

The OWC Mercury Elite Pro Dock is an awesome solution for anyone looking for a combination of port expansion along with huge capacity (up to 32TB).
Even ignoring the very useful ports, it’s excellent just for being relatively compact and portable, especially for photo and video shooters or just regular desktop use if only for its huge capacity and its hardware RAID built-in—no special software required.
