It really doesn't matter.

I have used several methods over the years when loading a new version of BB..

1. Everything on the C drive. No issue with a new computer and a really big drive. Especially if it's a dedicated DAW.

2. Program on C, files on a second drive.

3. Run it from the factory HD. Very similar to #2.

These all run sufficiently well. There's really no huge difference in loading times for the real tracks that I have noticed. Now days, due to laziness...I just run from the factory HD with a minimal install. A full install to the C drive or even to a secondary drive does take some time to transfer the files. The factory drive is ready to roll from the start.

It might take a second or two longer to load files from the external or secondary but nothing to worry about.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
