Given a constant number of partitions, I don’t see any advantage to splitting partitions among multiple log directories vs. keeping them all in one (per disk). You’d still have the same total number of topic-partition directories and the same number of topic-partition leaders. If you want to increase throughput, focus on using the appropriate number of partitions. — Peter Bukowinski
