This is why I have a USB Hub and MicroSD cards for drives that aren’t OS related.
I have
256GB Mac
256GB “Work In Progress” microSD Card (torrents, files I am working on, encoding, etc.)
2 1TB MicroSD Cards for DRM Purchases (iTunes and Apple TV) + Non DRM content (content I ripped and encoded to convert to digital and podcasts, audio, video, etc.)
I just really like the portability of SD Cards and USB sticks.
