Travelstar 5K500 is Hitachi's fourth-generation mobile drive to use perpendicular magnetic recording technology to deliver breakthrough capacity and reliability. Today's full-featured notebooks include premium speakers for enhancing a user's audio experience. These speakers can inadvertently cause vibrations within the system enclosure. To mitigate any adverse impact on system performance, the Travelstar 5K500 is the first mobile drive to feature Hitachi patented Rotational Vibration Safeguard (RVS) technology. RVS serves as an "early warning" system for the drive, enabling it to sense a possible disturbance in advance and take the necessary steps to stabilize the drive head and maintain performance.
