Western Digital software helps improve distributed storage TCO by pairing host-managed SMR HDDs with Kalista IO for Apache Hadoop and Ceph environments that need performance at scale. The solution delivers consistent, predictable performance while increasing storage density, which helps lower both CapEx and OpEx compared with CMR HDDs. Western Digital’s software-enabled host management of device state and data placement supports efficient operation across large deployments, making performance more reliable as systems grow. This collaborative approach gives organizations a practical way to optimize distributed storage, reduce cost, and maintain stable throughput without sacrificing scalability.
