There are two fundamental differences between the two drive families - spindle speed and storage capacity. The Scorpio Blue drives spin at 5,400 RPM and have a maximum capacity of 1 TB. The Scorpio Black drives, on the other hand, are limited to a maximum capacity of 500 GB but have a much higher spindle speed of 7,200 RPM. The Scorpio Black drives offer these key features :

- Desktop-class performance for notebook computers
- Low power consumption, thanks to IntelliSeek and SecurePark
- WhisperDrive technology for quieter operation and lower power consumption
- Reliable and rugged performance with WD ShockGuard technology

Today, we will look at the ultimate drive from the Scorpio Black family - the 500 GB WD Scorpio Black hard disk drive. With 500 GB of storage capacity packed into just two platters, this drive promises to provide the best combination of performance and storage capacity.
