Enterprise Storage Drive

The HGST Ultrastar 7K3000 0F12455 is a 2TB 3.5-inch internal hard drive built for enterprise storage systems. It spins at 7200 RPM with a 64MB cache and connects via a SATA 6.0Gb/s interface. The bare drive design targets servers and storage arrays that demand continuous operation.

Reliability Features

A 2.0 million hour MTBF rating and Dual Stage Actuator technology aim to reduce downtime in 24x7 environments. Enhanced Rotational Vibration Safeguard helps maintain performance when multiple drives operate in the same chassis. The fifth-generation five-platter mechanical design has been field proven by major OEMs since 2004.

Capacity Optimised Workloads

This drive suits buyers who need high-reliability bulk storage for enterprise applications running around the clock. It is not for builders who need faster random access speeds or lower latency for boot drives. Buyers who want more storage capacity per bay or a different interface such as SAS should look at other models.

Questions about this item

How often will the 2.0 million hour MTBF rating require drive replacement in a 24x7 server array?

The 2.0 million hour MTBF rating indicates high reliability for continuous operation; drives are typically replaced only upon failure or during planned hardware refresh cycles.

Does the 7200 RPM spindle speed create a throughput ceiling for sustained enterprise workloads?

The 7200 RPM speed combined with 64MB cache and SATA 6.0Gb/s interface determines the maximum sustained transfer rate for heavy workloads.

What are the heat and power characteristics of the 3.5 inch form factor during all-day operation?

The 3.5 inch form factor with 26.10mm height fits standard enterprise bays; power draw and heat scale with the 7200 RPM operation and 24x7 accessibility design.
