RAM concerns regarding large amount of files / media in one project.

For large projects with that much media, working in the old stand-alone project mode is not something I would choose. Premiere has to load a record of every file of that project into RAM/cache files. Not optimal.

The Production mode is very different. And runs with a ton less RAM/cache file usage. Which is why it's used on all long-form/doc work with Premiere. I'm a one-man shop, but I set up my year running in a Production. I can have access to all my b-roll/sound assets/graphics etc. in any project without ever having a duplication. Or slowing anything down.

You create a Production ... File/New Production. Premiere creates a file folder on disc where you specify. The you create subfolders from that Production panel in Premiere ... which also then makes subfolders on disc. Build your project organization with subfolder trees.

Then within those folders you create projects for holding assets. So you have a project that holds your Day 1, another for Day 2, or however you organized your Production.

You create projects for your sequences. Simply grab a clip from your media project to drag/drop onto a timeline that lives in your Sequences project. Premiere doesn't duplicate the needed reference data. It just grabs the data it needs from the other project but only as and when it needs it.

That is why a Productions operation uses so much less RAM/cache, and runs cleaner and faster. They have instructions on how to operate in Productions. It's quite different at first, but soon becomes easy to work within.
