Compatibility Information
The ST28000NT000 uses a 3.5-inch SATA interface and 512e sector formatting. Before installation, confirm that the NAS enclosure, server, or storage controller supports 28TB SATA hard drives and the required sector format. RAID compatibility and supported drive capacity depend on the host system, firmware, and configuration.
Although the drive is designed for demanding NAS environments, actual performance depends on the storage controller, RAID configuration, workload, cooling, and other components in the system.
