The question is how you will be using the storage. Are we talking video editing large files from a thunderbolt drive? Watching movies you want to store somewhere? Access documents?
For most things I would not even consider plugging physical devices in. I have my NAS with backups for large files at home like movies and such, for documents, programming files and such I use cloud storage. If I am away I can access my NAS as well if I need to.
