Enterprise 4TB SATA drive

The Seagate Constellation ES.3 ST4000NM0033 is a 4TB 3.5" internal hard drive built for enterprise storage arrays and servers. It spins at 7200 RPM with a 128MB cache and connects via a SATA 6.0Gb/s interface. The bare-drive packaging suits integrators and system builders populating multi-bay chassis.

Bulk-data workloads, not low-latency tiers

This drive suits administrators who need high-capacity, cost-efficient storage for bulk-data applications such as backups, archives or surveillance footage. It is not for workloads demanding the low access latency of solid-state media or for portable external enclosures.

7200 RPM spindle speed

The 7200 RPM spindle speed determines the sustained transfer rate and average latency for sequential workloads. Verify that your host controller and backplane support SATA 6.0Gb/s to utilise the full interface bandwidth.

Questions about this item

What is the first performance limit reached under sustained 7200 RPM operation?

The 128MB cache fills first during sustained write workloads, after which the SATA 6.0Gb/s interface governs throughput.

How much heat and power does the 3.5" drive produce when running all day?

The 26.10mm-high enterprise drive is built for continuous operation in multi-drive chassis where airflow manages heat from the 7200 RPM spindle.

Which SATA host interface must the system already provide for this bare drive to work?

A SATA 6.0Gb/s port and matching data and power cables are required; the drive has no onboard controller for other interfaces.
