Where the figures come from
Each row was read from the maker's own specification page for the model on October 12, 2026. "Not published" means the maker's page gives no figure, so none is stated here. Prices are live Amazon.com listings and change through the day.
A model is in the comparison only if its specification page was read and saved on the check date; other QNAP listings still appear in the price table.
