Hi, I am currently benchmarking Cassandra with three machines, and on each machine I am seeing an unbalanced distribution of data among the data directories (1 per disk). I am concerned that this affects my write performance, is there anything that I can make the distribution be more even? Would raid0 be my best option?
Details: 3 machines, each have 24 cores, 64GB of RAM, 7 SSDs of 500GB each. Commitlog is on a separate disk, cassandra.yaml configured according to Datastax' guide on cassandra.yaml. Total size of data is about 2TB, 14B records, all unique. Replication factor of 1. Thanks, Soerian
