Daisy Disk is incredibly intuitive to use. Almost immediately I was impressed on just how many ways you can actually "navigate" your hard drive. The free form interface made finding wasted space a breeze.
1.) The quality and presentation of this app are quite beautiful. The opaque black background that floats above my desktop is classy, and the color choices used for differentiating files and folders on your hard drive not only make for great eye candy, they enhance navigation.
2.) You're not limited to just scanning your Macintosh HD, you can scan Windows NTFS drives as well if you desire. They take a little longer, but the fact that I can use this program across multiple hard drives is a huge bonus.
3.) Navigation is quite wonderful. I can click down into my folders by clicking on any of the colored segments, go up a directory by pressing the central circle when desired (or by pressing the arrow button on the navigation bar), and select any of my Macintosh HD main folders by selecting them from the sidebar. It works the way you want it to, which makes for user friendly navigation even for the newest Mac users.
With this application, I've found over 50GB of space that I was able to identify and either delete, or move off to an external hard drive.
