One external raid (mirrored) that holds information only necessary for when I'm working at my desk. Within that drive I have an archive folder with past files that are rarely/ever needed. The folder structure is labeled broadly such as "documents" "media" and more specific folders within. For the file level I usually put a date at the beginning of the name going from largest to smallest (2017-6-21_filename). For sensitive documents; I put in encrypted DMG files using the same organization structure. As for all "working" documents, they're local to my machine under a documents or project folder. The documents folder is synced to all my devices and looks the same everywhere with a similar organization structure as my external drive. My projects folder is only local to my machine, which is a portable, and contains all the documents needed for that project. TL;DR Shallow folder structure with dates at the beginning of files essentially.
