(Admittedly the thresholds vary dramatically depending on what data you have, what kind of a target you are, what threat actors want to attack you etc. However, for sensitive data, there’s really no match for a dedicated secure file management platform. Once the encryption is above a certain amount, an attacker is forced to use the xkcd approach The company uses the latest encryption protocols for storage and data in transit, offers an optional two-step verification layer, and regularly tests its infrastructure for security vulnerabilities. You can use a key file if you want - but to be honest, using a long passphrase can secure the data to a level which requires an unfeasible timespan to break so it should be all you would need. One of the upsides with TrueCrypt or similar is that the passphrase/key/whatever never need to be visible to DropBox which means that an attacker can't do anything useful with your encrypted data unless they also compromise your home machine. If you have very sensitive data, you will want to use strong encryption. What would you normally do with your data on an insecure system? Yes - assume DropBox is an open, insecure system.
