Specifications

1  One GB is equal to one billion bytes and one TB equals 1,000GB  
  (one trillion bytes) when referring to hard drive capacity. Accessible  

 

  capacity may be less.

2  Intended for low duty cycle, non mission-critical applications in PC,    
  surveillance, nearline, and consumer electronics environments, which  
  may vary from application to application. Note that customer environ-   
  ments may vary from application to application. 

3  This MTBF target is based on a sample population in typical CE/ 

 

  surveillance product environment and is estimated by statistical 
    measurements and acceleration algorithms under normal operating    
  conditions. MTBF ratings do not predict reliability of an individual drive.

4  Portion of buffer capacity used for drive firmware. 1TB has 16 MB buffer.

5  Temperature tested at top cover surface
