To cut seek noise, SoftSeek technology streamlines read/write seeking algorithms, resulting in more efficient operation.
  
  
• NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
  
  
• IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise and vibration.
