Go Find Duplicates: blazingly-fast simple-to-use tool to find duplicate files
I use and test assorted duplicate finders regularly.
fdupes is the classic (going way way back) but it's really very slow, not worth using anymore.
The four I know are worth trying these days (depending on data set, hardware, file arrangement and other factors, any one of these might be fastest for a specific use case) are https://github.com/jbruchon/jdupes , https://github.com/pauldreik/rdfind , https://github.com/jvirkki/dupd , https://github.com/sahib/rmlint
Had not encountered fclones before, will give it a try.

rdfind is available for macOS; I've been using it on linux: https://github.com/pauldreik/rdfind

Deduplication on EXT4
You can use rdfind to find all duplicates in your experiments dir and replace files with hardlinks. This way files will occupy disk space only once and all inode references will be to the same disk location.
