Thunderbolt-dock planner
People matching docks to display count. The decision this page isolates is narrow on purpose: translate display count into a dock class. Fit and capacity are the expensive mistakes. Settle those before you commit to a finish or a brand.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank CalDigit, Anker, and OWC. It produces an explainable class so CalDigit TS4, Anker 555 Thunderbolt 4, and OWC 11-Port Thunderbolt Dock can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.
