So, I have a 6tb drive I got for film editing. I have two questions before I partition and fill it up: 1 - I am using the drive for a film project I already started with two other drives. What I want to do is partition the new drive into 3, using two of the partitions to duplicate the drives I already have. This makes sense if I can mount multiple partitions at the same time from the same drive? Can I do that? I assume so. But reading online i haven't found conformation. 2 - I know the rule of thumb is to keep 10% of a hard drive free. If I partition the drive, do I need to keep 10% of each partition free or is 10% overall OK?
