One GB is equal to one billion bytes, one TB equals 1,000GB (one trillion 

bytes) and one PB equals 1,000TB (one quadrillion bytes when referring 

to drive capacity.  Accessible capacity will vary from the stated capacity 

due to formatting and partitioning of the drive, the operating system and 

other factors.

2

MTBF target is based on a sample population and is estimated by statistical 

measurements and acceleration algorithms under nominal operating 

conditions.  MTBF ratings are not intended to predict an individual drive’s 

reliability. MTBF does not constitute a warranty.
