Capacity and Interface

The Seagate ST4000NC001 is a 4TB 3.5-inch internal hard drive built for enterprise storage arrays. It connects via a SATA 6.0Gb/s interface and spins at 5900 RPM with 64MB of cache. The bare drive is sold new and rated for continuous operation in multi-drive environments.

Sustained Throughput

The key specification is a sustained read data rate up to 170 MB/s, which sets realistic expectations for bulk data transfer. Average latency is 5.1ms and operating power stays under 4.3 Watts. These figures determine whether the drive meets throughput and thermal targets for high-density deployments.

Suited for Bulk Archives

This drive suits builders scaling out cost-effective, low-power storage for unstructured data in datacenters or cloud archives. It is not for workloads demanding low-latency random access or high IOPS, such as primary databases or virtualisation hosts. Buyers needing faster access times or higher spindle speeds should look at performance-class drives.

Questions about this item

What does the 170 MB/s sustained read rate mean once the drive is installed in a real machine?

It is the maximum sequential throughput the drive can deliver over the SATA 6.0 Gb/s link; random workloads and system overhead will reduce everyday speeds.

What does the SATA 6.0 Gb/s interface cap in practice?

The interface limits burst transfers to 6.0 Gb/s, so the drive cannot exceed that ceiling even if its internal media were faster.

What does the 3.5-inch form factor need to fit or mount in a system?

It requires a standard 3.5-inch drive bay with SATA data and power connectors and mounting screws.
