Last week I ordered my new Mac Pro with a 1TB SSD. My current boot drive has 950GB worth of stuff on it so I want to free up some space before the new machine arrives. In looking around, one of the biggest space hogs is my iMovie Library which takes up almost 160GB. By default, the iMovie Library is placed in the Movies directory. In order to free up space can I simply copy the iMovie Library to another drive? Ultimately, since I bought a Drobo 5D to house the drives that sit in my current Mac Pro, I want to move the iMovie Library over to it and run it via TB. Doable? Advisable?
