Looking for the best USB Dock to plug in G tech USB hard drives that seem to keep piling up. When I tried a dock in the past (can't recall which one) it kept ejecting the drives when the computer was turned off/wouldn't automatically see all drives each time.

Curious on what I need that works well. Ideally it would plug into one of the USB ports on the iMac as the two usb-c ports are taken.
