160GB 7200 RPM Notebook Drive

This 2.5 inch laptop hard drive offers 160GB of storage with a 7200 RPM spindle speed and 16MB cache. It connects via a SATA 1.5Gb/s interface and uses third-generation PMR technology. The bare drive suits users upgrading older notebooks that require a SATA 1.5Gb/s mechanical drive. It is not for buyers needing higher capacities or solid-state speeds.

Sustained 7200 RPM Operation

The drive maintains its 7200 RPM speed under continuous workloads rather than throttling back. Average seek time is 10ms with an average latency of 4.2ms. The 16MB buffer helps smooth data flow during extended read or write sessions. It is not for workloads demanding sustained transfer rates beyond what the SATA 1.5Gb/s interface can deliver.

Low Power Draw and Noise

Average seek power consumption is 2.6W while standby power drops to 0.25W. This low draw helps preserve notebook battery life during normal use. The efficient design aims to balance performance with thermal output. It is not for systems requiring enterprise-grade vibration tolerance or advanced power-management features beyond basic standby.

Questions about this item

How much power does the 7200 RPM Travelstar 7K200 draw during sustained seeks?

The drive averages 2.6W during seek operations and drops to 0.25W in standby, so all-day use keeps heat and battery drain low.

Does my laptop need a SATA 1.5Gb/s controller and a 2.5" bay to install this bare drive?

Yes, it requires a native SATA 1.5Gb/s interface and a standard 2.5-inch internal slot; no caddy or adapter is included.

Will the SATA 1.5Gb/s link bottleneck this drive when paired with an older SATA I chipset?

The 1.5Gb/s (150 MB/s) interface matches the drive's native speed, so an original SATA I controller runs it at full rate without throttling.
