Hi Adam, I am not the person to answer having not used Cassandra, but have spotted this being discussed on the list recently on a long thread:
Search for "Cassandra vs HBase" on this page: http://mail-archives.apache.org/mod_mbox/hadoop-hbase-user/200909.mbox/thread There is also an article: http://www.roadtofailure.com/2009/10/29/hbase-vs-cassandra-nosql-battle/ Hope this helps with your background reading.
