Method and scope

Intel Core i7-6700K, Samsung 860 EVO SATA SSD, warm Windows file cache, median of five runs per method. DiscReveal: the published Windows app, already open in list view, measured from a real click to the fully displayed final results. Commands: process start to completion, without printing file lists to the screen. Actual times depend on your drive and files.

This test compares drive scanning with Windows commands and a script, not other graphical disk analyzers. It does not measure duplicate search.
