Purpose-built 2.5-inch SATA drive

This 2.5-inch SATA hard drive delivers 1TB of storage at 7200 RPM with a 64MB cache. It carries the Dell WF12F part number and the Seagate ST91000640NS model number. The drive supports S.M.A.R.T. monitoring and hot-swap capability. It is supplied as a bare drive without accessories.

Suits 2.5-inch SATA bays.

This unit fits systems that accept a 2.5-inch SATA drive with a 6Gb/s interface. Builders working with 3.5-inch drive cages or laptops that require a thinner z-height cannot install this drive. Buyers needing a different physical size or a non-SATA interface should consider other options.

7200 RPM rotational speed

The spindle runs at 7200 RPM, which determines the drive's sustained transfer rate and access latency. This speed is the primary performance figure for this model. Match it to workloads that benefit from higher rotational velocity over lower-power alternatives.

Perguntas sobre este artigo

Will the 2.5" ST91000640NS fit a standard 3.5" desktop drive bay?

The drive is a 2.5" form factor so it needs a 2.5" bay or a 3.5" adapter bracket to mount securely in a desktop chassis.

Which SATA cable and power connector does the Constellation.2 drive require for installation?

Connect a standard SATA data cable to the 6-Gb/s interface and a SATA power connector from the PSU; ensure the data cable clicks fully into the port.

Does the 64MB cache or SMART data indicate when the 7200RPM drive should be replaced?

Monitor SMART attributes such as reallocated sectors and seek errors; rising values signal wear and the need to replace the drive before failure.
