Enterprise 12TB SATA drive

The HGST Ultrastar He12 HUH721212ALE600 is a 12TB 3.5-inch internal hard drive built for enterprise storage workloads. It spins at 7200 RPM over a SATA 6.0Gb/s interface and is rated for up to 550TB of data transferred per year. A 2.5M-hour MTBF rating underlines its design for continuous operation in servers and storage arrays. The drive uses a bare-drive form factor and includes a power-disable pin on the connector.

Suited for high-capacity arrays, not legacy builds

This drive fits RAID arrays, distributed file systems and block-storage servers that need dense, reliable capacity. The power-disable pin (pin 3) means it will not work with older power supplies or backplanes that lack support for the feature. Buyers who need a simple drop-in drive for an older desktop or external enclosure should look at models without the power-disable implementation.

12TB raw capacity with enterprise headroom

At 12TB the drive holds large media libraries, backup targets or database volumes in a single bay. The 550TB-per-year workload rating provides headroom for heavy write cycles such as RAID rebuilds, where the Rebuild Assist feature helps maintain array performance. Sequential throughput is limited by the SATA 6.0Gb/s link, so sustained transfers will not exceed that interface ceiling.

Questions about this item

Does my motherboard need a SATA 6.0Gb/s port for this 12TB drive?

The drive uses a SATA 6.0Gb/s interface and will also run on older SATA ports at reduced speed.

Will the power-disable pin 3 feature work with my older PSU?

The power-disable pin 3 feature may not function with legacy systems or older PSUs that do not support the specification.

How can I verify the 7200 RPM drive is healthy after installation?

Check SMART data for reallocated sectors and confirm sustained transfer rates match the 6.0Gb/s SATA link speed.
