High-capacity, reliable hard drives are of the utmost importance to desktop users who are running multimedia systems, advanced computing, and other data-intensive applications. WD Caviar desktop hard drives incorporate advanced features that contribute to a cool, fast, and reliable computing environment.
WD Caviar SE16 750 GB hard drives include WD's SecurePark technology, which parks the recording heads off the disk surface during spin up, spin down and when the drive is not operating. Unlike drives without SecurePark, the feature improves non-operational shock tolerance by ensuring that the recording heads never touch the disk surface, reducing head and surface wear and enhancing long-term reliability.
Used on WD high-capacity hard drives and to further ensure reliability, WD's StableTrac technology was incorporated. StableTrac's motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. Most current hard drive designs feature motors that are only attached on the bottom of the hard drive, which can cause missed read revolutions. StableTrac allows end-user data to be retrieved fast without missing revolutions.
