       WD Caviar SE16 next-generation SATA hard drives feature a 16 MB 
        cache for lightning-fast performance. Yes, these reliable drives 
        are fast, but they still deliver technologically advanced acoustics 
        and cool operation. Designed for high-performance computers, 
        multimedia and gaming systems. 
* 16 MB cache 
   Bigger cache means faster performance. A massive 16 MB cache combined 
   with up to 300 MB/s transfer rate make these ultra-fast drives the 
   perfect solution for the fully loaded PC with a fast processor. 
* Cool operating temperature 
   WD hard drives are designed to have the lowest power consumption of any 
   high-capacity desktop-class hard drive which lowers the operating 
   temperature for enhanced drive reliability. 
* Whisper quiet 
   These highly-reliable drives deliver technologically advanced acoustics. 
   With its WhisperDrive and SoftSeek technologies, WD has minimized noise 
   to levels virtually imperceptible to the human ear in home and business 
   environments. 
* Data Lifeguard
   An exclusive set of data protection features, including shock 
   protection, an environmental protection system and real-time embedded 
   error detection and repair. WDs Data Lifeguard technology automatically 
   finds, isolates, and repairs problems that may develop over the life of 
   a hard drive. 
* Data Lifeguard Tools
   Software utilities designed for WD hard drives that work with the 
   embedded Data Lifeguard features to make hard drive installation, 
   diagnostics and repair both simple and worry-free. 
* Shock Guard
   Instantaneously protects the hard drive against damage from bumps and 
   vibrations while it is running. This technology enables WD Caviar drives 
   to achieve industry-leading shock specifications.
