Enterprise Capacity Drive

The HGST Ultrastar A7K2000 delivers 1TB of storage on a 3.5-inch SATA 3.0Gb/s interface. It spins at 7200 RPM with a 32MB cache and an 8.5ms average seek time. This bare drive is built for enterprise storage arrays and servers that require continuous operation.

Sustained Enterprise Workload

A 24x7 duty cycle and a targeted 1.2 million hours MTBF indicate reliability under constant read and write demand. Enhanced Rotational Vibration Safeguard helps maintain performance when multiple drives operate in the same chassis. The 32MB buffer smooths burst traffic without degrading long transfers.

SATA 3.0Gb/s Interface Limit

The 3.0Gb/s SATA link caps maximum sequential throughput below the 6Gb/s ceiling of later revisions. Systems limited to this generation cannot exploit the higher bandwidth of newer drives. Buyers needing faster interface speeds must select a drive with a 6Gb/s SATA or alternative connection.
