Enterprise 4 TB SAS Drive

The Seagate ST4000NM004A is a 3.5 inch hard drive built for enterprise storage arrays and rackmount NAS systems. It delivers 4 TB of capacity through a SAS 12Gb/s interface spinning at 7200 RPM with a 256 MB cache. The bare-drive packaging suits integrators who install drives into hot-swap chassis or storage appliances.

IT teams needing high-throughput shared storage

This drive suits administrators who require the dual-port reliability and consistent performance of SAS for multi-user databases, virtualisation hosts or backup targets. It is not for buyers who need a single-port consumer interface or who lack a SAS backplane and compatible controller in their enclosure.

SAS 12Gb/s interface

The defining specification is the SAS 12Gb/s connection, which determines whether the drive can communicate with your controller and backplane. Verify that your storage system supports this interface and the 3.5 inch form factor before purchasing.

Questions about this item

What drive bay size and interface does the 3.5-inch SAS 12Gb/s drive require?

The drive fits a standard 3.5-inch bay and connects via a SAS 12Gb/s backplane or controller.

How is the bare drive installed in a rackmount NAS and what step is often missed?

Slide the drive into the hot-swap tray, secure it with the tray screws, and insert the tray until the SAS connector seats fully; the step often missed is fastening the tray screws before insertion.

When will the 4 TB enterprise drive with 256 MB cache need replacement under heavy workloads?

Enterprise drives are rated for continuous operation; plan replacement after five years or when SMART attributes indicate wear.
