320GB 7200RPM SATA laptop drive

This Western Digital BLACK internal hard drive provides 320GB of storage in a 2.5 inch form factor. It spins at 7200RPM and connects through a SATA 6Gb/s interface with a 16MB cache. The drive is designed specifically for laptop installations.

Suits laptops needing faster mechanical storage

Users who require higher capacities or solid-state speeds should consider other options. The 320GB limit and mechanical latency make it unsuitable for large media libraries or primary OS drives where responsiveness is critical. Buyers needing 3.5 inch desktop form factors cannot use this drive.

2.5 inch SATA 6Gb/s interface decides fit

This drive only fits systems with a 2.5 inch SATA drive bay and a compatible SATA controller. The 7200RPM spindle speed and 16MB buffer are fixed characteristics. Verify your laptop accepts 2.5 inch SATA drives before purchasing.

Questions about this item

Will this 2.5" SATA drive fit a standard laptop drive bay?

Yes, it uses the 2.5-inch form factor and a SATA 6Gb/s interface, matching the standard laptop drive bay dimensions and connector.

What is the correct way to install this drive in a laptop, and what step is often missed?

Slide the drive into the bay until the SATA connectors seat firmly, then secure it with the caddy screws; the step often missed is fastening the caddy screws, which leaves the drive loose.

When should the 16MB cache drive be replaced in a laptop used for photo and video editing?

Replace it if you hear unusual mechanical noise, see SMART reallocated-sector warnings, or notice sustained transfer speeds dropping well below the 7200RPM rating.
