Rotational Vibration Safeguard (RVS)
One of the greatest hindrances to hard disk performance is vibration. Like a needle on a record, the disk drive’s head must try to follow narrow data tracks in order to read (or write) information. These problems are particularly acute in multi-drive systems, because drives tend to be installed alongside each other, in arrays. The vibration caused by the rotation and seek activities of nearby drives can affect the whole array, progressively disturbing the operation of each drive in the system. The drop in performance can be significant. That's why the Deskstar NAS hard drive has an advance Rotational Vibration Safeguard (RVS) that anticipates disturbances and counteracts them, maximizing performance in the most arduous conditions. If the RVS sensors feel a vibration rippling through the drive, they send a signal to the actuator that controls the head’s position. The actuator then compensates for the disturbance, counteracting it with an equal and opposite force. In this way, the head is able to 'ride' the vibration and stay on track, helping to prevent data loss or corruption.
