Zoned Storage is a class of storage devices that enables host and storage devices to cooperate to achieve higher storage capacities, increased throughput, and lower latencies. The zoned storage interface is available through the SCSI Zoned Block Commands (ZBC) and Zoned Device ATA Command Set (ZAC) standards on Shingled Magnetic Recording (SMR) hard disks today and is also being adopted for NVMe Solid State Disks with the upcoming NVMe Zoned Namespaces (ZNS) standard.
