+2 - I feel like this is a (potentially intentional) blind spot for Dropbox and its ilk. I'm paying for 1 TB because I need that capacity, for my photo library, music, etc. - and I want to pay dropbox to make this work well with small fast SSDs. While there's various tricks you can employ to get this working, they're all a pain in one way or another. "A user who wants to back up and sync lots of media, and selectively offload it onto cloud storage to save local disk space" is probably not such a rare animal. And if I'm not feeling charitable, I would guess that this isn't explicitly supported because if it was, many more Dropbox users would start eating a lot more of their quota than they currently do.
