In legacy versions of Final Cut Pro you had to set scratch disks to manage where your video data and cache files would be stored. And you were limited to twelve drives at any one time. Final Cut Pro X makes it easier to specify where your video and project files are stored, automatically saving your Events and Projects in the Movies folder by default. But have no fear, your Events and Projects can be stored on any drive connected to your Mac, and you can easily move existing Events and Projects between drives when needed to keep your stories organized.
