320 GB 7200 RPM notebook drive

The Western Digital Scorpio Black WD3200BEKT is a 2.5 inch SATA 3.0Gb/s hard drive with a 320 GB capacity and 7200 RPM spindle speed. It targets users who need desktop-class performance inside a notebook chassis. The 16 MB cache and 4.2 ms average latency support responsive operation for power computing tasks.

Upgrade from 5400 RPM laptop drives

Replacing a standard 5400 RPM notebook drive with this 7200 RPM model delivers faster data access and shorter load times for applications and large files. The jump is worth it when the workload demands higher sustained throughput and the system can accommodate the 9.5 mm height. It is not suited for ultra-thin laptops limited to 7 mm drives or for users who need solid-state speed.

Check SATA interface and 9.5 mm bay

Verify that the notebook provides a SATA 3.0Gb/s connection and a 2.5 inch drive bay with at least 9.5 mm clearance. The bare drive ships without mounting brackets or cables, so reuse existing hardware or source them separately. Confirm the system BIOS recognises 320 GB capacities before ordering.

Questions about this item

Will the 9.5mm height and 2.5" form factor fit my laptop drive bay?

Yes, the drive measures 9.5mm high, 69.85mm wide and 100.20mm long, matching the standard 2.5" SATA notebook bay used by most laptops.

Does the SATA 3.0Gb/s interface need any jumper or driver setup during installation?

No jumpers are required; connect the 7-pin SATA data and power cables, then initialise the 320GB volume in your OS disk utility — the step often missed is creating a partition before use.

How often should I run diagnostics on the 16MB cache and 7200 RPM mechanism?

Run the manufacturer's Data Lifeguard Diagnostic once a year or after any physical shock; the utility checks the cache, platters and Shock Guard sensors for early wear signs.
