This seems like a good time to resurface the worlds best Quora answer, by Michael Wolfe. Answering “Why is Dropbox more popular than other tools with similar functionality?”: Well, let's take a step back and think about the sync problem and what the ideal solution for it would do: There would be a folder.

Needless to say this didn't scale well, and there were about 750k files on the structure. Most of this was archival, but we simply didn't have the time or care enough to reduce the number of files.. we just wanted to be able to sync this to cloud data as is. Many files were super small, so never an absolute size thing just a LOT of files. And a chunk would keep changing throughout the day.

I tried OneDrive on this.. what a nightmare. I tried owncloud, bittorrent sync, some others I can't even recall. Granted this has been about 3-4 years since I really tried some other ones with lots of files, but I was so annoyed every time I did.
