Dropbox works well for small files that you need to share with others. However, if you use it to back up large amounts of data ... say >100GB, the experience of using it is very poor. It consumes large amounts of CPU continually. It takes forever to run to completion (literally in some cases, in my case it ran for weeks before I gave up on it). An external hard drive is of comparable cost to Dropbox, and a one-time cost, not something you need to pay for, forever. It runs to completion in 20 minutes. You can keep multiple versions of it in different physical locations. It's conceptually simple with fewer points of failure.

Personally I tried using several different cloud backup solutions, but I gave up on them. A few encrypted external hard drives, updated every month or two in a repeatable way (e.g. a bash script), one at home, one at work ... and backup is a solved problem. Of course, to each their own.

Then you had some problem. I have ~1TB in Dropbox, files small and large. No problems with sync. Once in a while it does go crazy, eats up a lot of CPU and takes 1 hour to get in proper sync. It’s annoying, but luckily it’s rare. And it goes with me everywhere. How do you access external drive from your phone anyway?

The point of the external hard drives is really just to have a backup. I don't have a 1TB collection of files that I need to access from multiple places. So I would never try to access my big backup from my phone. I don't do that kind of work from my phone, ever. If you're in that situation, something like Dropbox might help, provided that it doesn't eat all your CPU. Good for you! Glad it's working out.
