I made a mistake in my earlier posts. My 2 internal HDs are 2TB each, not GB.
I do back up all my content, in my own standard messy and disorganised way.
But my main concern is rendering time within FCP really. That is my #1 issue… I was hoping there would be something i could do, or buy, or whatever so that the time waiting for this process to happen could be drastically reduced.
