It's actually somewhat unclear. They say that they support ".raw" files, but that suffix is only used for raw files from Kyocera Contax and Panasonic cameras. They specifically don't list .NEF (Nikon), .CR2 / .CRW (Canon), or .DNG (the "standardized" raw file format).

I can't seem to find anywhere whether they include free video storage as well. I realize there are limitation on video size, but I have thousands of short videos that fit their limitations.

Thousands of short videos, eh? ;)

Indeed! I work on a mobile app, well, a whole system really, that helps compose short videos into one larger video.

Do they have a good way to stream videos that you upload? If so, I may just upload all of my movies and use it like a plex server.

I was hoping the same thing, but the max length on a video is 20 minutes. Drats, foiled again!

Beyond filetype, they limit videos to under 20 minutes, so probably won't be replacing Plex anytime soon.

I wonder what the definition of "unlimited" is?

That should be quite simple to test. Just generate a bunch of random images and start uploading. Let us know when they ban you, and declare you the enemy of the state.
