This feature also helps in maintaining a consistent and higher fly-height across the disk in standard mode. Incorporation of SilentSeek and NoiseGuard features minimizes noise to give you a noise free peaceful surrounding. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.
