Should I stop Spotlight from indexing my fast drive?
Short answer: Usually leave it on, so moved files stay searchable. Indexing is busiest right after connecting the drive or adding many files and can briefly block ejecting. Excluding the drive in Spotlight settings hides its files from search.
Usually no. Leaving Spotlight on means files you moved to the drive can still be found by searching, just as before. Indexing runs mostly after you first connect a drive or add lots of files, and then settles down.
Two things to know: Spotlight indexing can briefly stop the drive from ejecting (Storage Studio will tell you something is still using it), and if you do add the drive to Spotlight → Privacy in System Settings, files on it will no longer appear in searches.
