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  
  will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors. 

2  Advanced Format drive: 4K physical sectors with 512 emulation

3  Portion of buffer capacity used for drive firmware

4  Intended for low duty cycle, non mission-critical applications in PC, nearline, and consumer electronics environments, which may vary from  

 

  application to application. Note that customer environments may vary from application to application
