First of all, that might not be the right approach to choose the underlying storage. You should choose HDFS or HBase depending on whether the data is going to be used for batch processing or you need random access on top of it. HBase is just another layer on top of HDFS. So obviously the queries running on top of HBase are going to be less efficient. So if you can get away with using HDFS, I would say that is the best and simplest approach.
