Enterprise bulk storage

The Seagate ST5000NM0054 is a 5TB 3.5-inch internal hard drive built for 24x7 enterprise workloads. It connects via a SAS 12Gb/s interface and spins at 7200 RPM with a 128MB cache. The bare drive is engineered for reliable access to unstructured data in multi-drive chassis.

Capacity and headroom

Rated for 550TB per year, the drive handles sustained sequential and random I/O far beyond desktop-class limits. Eighth-generation technology and dual processors maintain consistent throughput under heavy loads. Workloads exceeding the annualised rating or needing ultra-low latency will run out of headroom.

Thermals noise and power

Improved power and cooling efficiencies lower the energy needed for continuous operation. On-demand PowerChoice technology reduces draw during idle periods based on T10/T13 standards. Rotational vibration tolerance and a humidity sensor keep performance stable across varying chassis thermals.

Questions about this item

Will the ST5000NM0054 work in a server backplane that only supports 6Gb/s SAS?

The drive uses a SAS 12Gb/s interface that is backward compatible with 6Gb/s and 3Gb/s backplanes, so it will operate at the slower link speed without any configuration changes.

How can I verify the 7200 RPM spindle and 4.16ms average latency are performing correctly after installation?

Run the manufacturer's SeaTools diagnostic or any SMART-capable utility; the reported rotational speed should read 7200 RPM and the seek-time metrics should align with the 4.16ms average latency specification.

Since the packaging is listed as Bare Drive, what exactly ships in the box and what must I source separately?

Only the 3.5" SED enterprise hard drive itself is included; you will need to provide a SAS 12Gb/s data cable, a compatible power connector, mounting screws and any tray or caddy required by your chassis.
