No one ever mentions Couchbase here, I guess it's a bit under the radar despite being used by so many big companies. I used it back when I was at Blizzard and thought it was pretty amazing. It's sort of like, what MongoDB could be if it was actually good. Ridiculous speed and scalability, and the new versions have included analytics and full-text search. Give it a look.

the question with many databases using rotational based storage engines is not how much you want to store, but how much you want to query. Couch requires 99% cache hit rates for queries, they tell you to add memory if you are lower. which really makes it an in memory database with a disk based backing store, suitable for modest data sizes. i have also never seen a positive jepsen test, so i believe it is known to lose data in split brain modes.

Not open source?
Not even transparent pricing?

The Community Edition is open source, though the Enterprise Edition has some proprietary extensions.
It’s admittedly not at all obvious from the repo name, but the following is the top level repo for Couchbase Server (which uses Google’s `repo` tool): https://github.com/couchbase/manifest
