Apple has never recommended defragging hard drives. In fact, there are white papers demonstrating that Apple is absolutely right and that it's counterproductive. Doesn't stop people from selling apps that have no other purpose than to separate you from your money.

Mine sits on a shelf. I have a 2T SSD onto which my Real Tracks/Audiophile libraries are loaded along with Komplete, SampleTank and a few others. Drums uses 68gB and Real Tracks takes up 1.22tB of drive space.

With SSDs, defragging or running any so called disk maintenance utilities can slow them down and shorten the life of the drive. The better apps like TechTool Pro will not run those utilities on an SSD while the crapware only has a caution in tiny type that running iDefrag is not recommended but giving them $39 is.
