Our take on the Western Digital Black 500Gb 7200RPM Serial ATA-6.0Gbps 16MBb Cache 2.5-Inch Internal Mobile Hard Drive

The WD Black WD5000BPKX is a 500GB 2.5-inch internal hard drive spinning at 7200 RPM with a 16MB cache and a SATA 6 Gb/s interface. It is built for laptops, small-form-factor desktops and consoles that take a 9.5mm-tall drive, and it targets speed rather than capacity. Its dual processor and dynamic cache help it beat 5400 RPM laptop drives in everyday load times, but it runs louder and warmer and holds less than the 1TB and 2TB drives in the same class. Owners rate it as a dependable boot and game drive for older machines.

Yes. At 7200 RPM with a 16MB cache it boots and loads noticeably faster than typical 5400 RPM laptop drives.
