Consistency is a safety property. HyperDex, Hbase and BigTable all provide linearizability, which has a well-defined meaning. Cassandra does not, and most of its descriptions of consistency only refer to the behavior of the system, and not the properties you can rely upon. Pointing to the number of replicas read or written only clouds the issue.
