Unbalanced read latency among nodes in a cluster

I setup a two cassandra clusters with 2 nodes each. Both use random partitioner. It's strange that for each cluster, one node has much shortter read latency than the other one This is the info of one of the cluster: Node A: read count 77302, data file 41GB, read latency 58180, io saturation 100%
