HP 2TB 7200 RPM SATA Hard Drive

This HP 507632-B21 is a 2TB 3.5-inch internal hard drive spinning at 7200 RPM with a SATA 3.0Gb/s interface. It is built for entry server and external storage environments where economical reliability and large capacity are the priority. The drive suits system builders who need bulk storage for backups, archives or secondary data volumes. It is not for workloads demanding the low latency or high throughput of solid-state media.

Build integration with SATA 3.0Gb/s

The drive connects through a standard SATA 3.0Gb/s port and fits any 3.5-inch drive bay using the same power and data cables as other SATA hard drives. Its midline design targets external storage enclosures and entry-level servers rather than high-performance desktop arrays. No special controller or tray is required beyond what a typical server chassis provides. Builders who need a 6Gb/s SATA link or hot-plug trays not included with this model should verify compatibility first.

Sustained load behaviour at 7200 RPM

At a constant 7200 RPM the drive delivers steady sequential throughput for long backup windows and archival writes without the thermal throttling seen in faster-spinning enterprise units. The 3.0Gb/s interface caps peak transfer rate, so sustained performance settles at the link limit rather than the media limit. This makes output predictable during multi-hour jobs. Workloads needing higher sustained bandwidth than 3Gb/s will be constrained by the interface.

Questions about this item

What is the sustained transfer rate limit of the SATA 3.0Gb/s interface?

The SATA 3.0Gb/s interface caps sustained throughput at 3.0 Gb/s.

How much heat and noise does the 7200 RPM mechanism produce during continuous operation?

The 7200 RPM spindle generates typical mechanical-drive heat and audible seek noise under all-day workloads.

Which drive bay and cable does my system need for this 3.5" SATA hard drive?

A standard 3.5-inch internal bay and a SATA data plus power cable are required.
