cassandra

I am currently running 4 cassandra nodes with the following hardware in a Apache Cassandra cluster:

AMD Athlon 64 X2 6000+
8G RAM
750G hard disk

It shows not such a good writing performance and a really bad read performance with sometimes also timeouts. I was wondering if it makes sense to add 2 nodes with a different hardware (8 CPUs and more RAM) to improve this. Or does a cassandra cluster works best with the same hardware in every node?

Thanks & best regards
