CouchDB
Metal Toad stores lots of data well with CouchDB
What is CouchDB

CouchDB is a distributed, schema-free, document-based database server, accessible via a RESTful JSON API. It is query-able and indexable, featuring a table oriented reporting engine that uses JavaScript as a query language. It featurs a robust, incremental replication system with bi-directional conflict detection and management.
Massively Scaling Document Storage
CouchDB allows unprecedented performance and scalability. Clever usage of server-side javascript (used to query and output data) create an end-to-end solution for highly available and concurrent systems. CouchDB can also be used as an indexed filestore with data attached to each file uploaded.
