Enough for what? :)
It's sort of like beauty in the eye of the beholder. Not everyone uses their systems for the same things. For surfing the web you might find it fine not to defrag for a month or 2. If you routinely mux video files you might defrag every day.
That said, I like Puran Defrag. It's free and has some nice options without getting "too thorough." I don't want to spend 4 days defragging my drive when 15 minutes is good enough(for my usage.)
