Purpose-built capacity

The Seagate ST4000NC000 is a 4TB 3.5-inch internal hard drive built for continuous operation in desktop and entry-level server environments. It spins at 5900 RPM with a 64MB cache and connects through a SATA 6.0Gb/s interface. The bare-drive unit includes Instant Secure Erase for simplified retirement.

Fit and limits

This drive suits users who need affordable, always-on storage for backups, archives or replicated data sets where sustained throughput matters more than peak speed. It is not intended for high-performance gaming, workstation scratch disks or workloads demanding low latency and high IOPS.

Headroom and boundaries

At 4.3 watts typical operating power the drive leaves ample thermal headroom in multi-bay chassis. The 4TB capacity handles large media libraries and long-term retention policies comfortably. Sequential transfers will saturate the SATA link before the platters become the bottleneck, while random access tops out at the mechanical limits of 5900 RPM and 5.1ms average latency.

Questions about this item

What SATA interface does my motherboard need to support the ST4000NC000?

The drive uses a SATA 6.0Gb/s interface and works with any SATA revision; it will negotiate the highest speed both ends support.

Will the 5900 RPM spindle speed and 64MB cache bottleneck an older SATA 3Gb/s controller?

The drive negotiates down to 3Gb/s automatically; sustained throughput stays within that link so the older controller will not be a practical limit.

How can I confirm the Instant Secure Erase feature is active after installation?

Use a tool that reads the drive's security status — such as hdparm -I or SeaTools — and verify the "SED" or "ISE" field shows supported and enabled.
