In my tests compressing with lzop sstables (with cassandra compression turned on) resulted in approx. 50% smaller files. Thats probably because the chunks of data compressed by lzop are way bigger than the average size of writes performed on Cassandra (not sure how data is compressed but I guess it is done per single cell so unless one stores)
