What exactly does the restore argument "With Replace" do? I'm looking at needing to restore a database back to a beginning point on a regular basis, and I've been trying to figure out if there are any disadvantages to using Restore With Replace versus Dropping/Deleting the database entirely and restoring it.
Will "With Replace" wipe the log files and reset whatever bits might be left in system databases as well? It seems that it would be much quicker, as I don't have to wait for the database to finish dropping (the database in question is around 2TB). I've already checked the TechNet article on the Restore arguments, it doesn't go into this specific question.
