Seagate Constellation 160GB 2.5" SATA Drive

The Seagate Constellation ST9160511NS is a 160GB 2.5-inch internal hard drive built for laptop and compact system upgrades. It spins at 7200 RPM with a 32MB cache and connects via a SATA 3.0Gb/s interface. The bare drive measures 14.8mm in height and 70mm in width.

Suits 7200 RPM 2.5" bays; not for thinner slots

This drive suits users replacing a 7200 RPM SATA drive in a 2.5-inch bay that accepts a 14.8mm height. It is not for systems that only accept thinner drives. Buyers needing more capacity or a different physical thickness should look elsewhere.

14.8mm drive height decides fit

The single specification that decides fit is the 14.8mm drive height. Verify that your laptop or enclosure explicitly supports this thickness before purchase, as many modern slim designs require a smaller form factor.

Questions about this item

What is the 160 GB capacity limit for sustained write workloads?

The drive provides 160 GB of storage; sustained write throughput is governed by the 7200 RPM spindle speed and the SATA 3.0Gb/s interface.

How much heat and noise does the 7200 RPM spindle generate during all-day operation?

The 7200 RPM mechanism produces typical laptop-class acoustic and thermal output; the 14.8 mm height and bare-drive design rely on the host chassis for cooling.

Which SATA host controller and 2.5 inch bay with 14.8 mm clearance must my system already have?

A SATA 3.0Gb/s port and a 2.5 inch drive bay that accepts a 14.8 mm tall drive are required for installation.
