Ultrastar DC HA340 12TB enterprise drive

The Western Digital Ultrastar DC HA340 is a 12TB 3.5 inch internal hard drive built for servers and storage systems. It uses a SATA 6.0Gb/s interface and conventional magnetic recording technology. The drive spins at 7200 RPM and presents a 512e format to the host. It is supplied new in retail or OEM packaging.

Sustained 7200 RPM workloads on SATA

Under continuous operation the 7200 RPM spindle delivers consistent throughput for sequential workloads such as bulk data ingest, backup targets and video surveillance recording. Conventional magnetic recording avoids the latency spikes associated with shingled writing during long write passes. The SATA 6.0Gb/s link sustains the data rate without the protocol overhead of faster interfaces.

Verify 3.5 inch bay and SATA cabling

Before ordering confirm that your chassis has a free 3.5 inch drive bay with adequate cooling airflow for a 7200 RPM unit. Ensure the motherboard or controller provides a SATA 6.0Gb/s port and that both data and power cables reach the mounting location. The 512e logical sector size requires an operating system or RAID controller that supports 4K native emulation.
