Constellation.2 250GB 7200 RPM SATA drive

This Seagate Constellation.2 ST9250610NS is a 250GB 2.5-inch enterprise-class internal hard drive. It spins at 7200 RPM with a 64MB cache and connects via a SATA 6.0Gb/s interface. The bare drive is designed for server and nearline storage deployments.

Suited for high-density server racks.

The 15mm z-height fits dense server bays that maximise footprint up to 76TB per square foot. It delivers 1.4M hours MTBF and idles at 2.52 watts for efficient nearline operation. Builders needing a slimmer drive for standard laptop bays or portable enclosures should look elsewhere.

15mm z-height governs chassis fit

The physical thickness of 15mm decides whether this drive installs in your target system. Server chassis built for 15mm enterprise drives will accept it; thinner consumer bays will not. Verify the drive bay specification before purchase.

Questions about this item

What is the sustained idle power draw of the ST9250610NS?

The drive consumes under 2.52 watts at idle, keeping power draw low for dense 15 mm server bays.

How much heat and noise should I expect from this 7200 RPM enterprise drive during all-day operation?

With idle power under 2.52 watts and a 15 mm z-height, it runs cool and quiet enough for continuous nearline workloads.

Does my server backplane need a specific SATA revision to support the 6.0Gb/s interface on this Constellation.2 drive?

It connects via standard SATA 6.0Gb/s, so any backplane or controller with a SATA 6Gb/s port will work.
