One MB is equal to one million bytes, 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.

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

statistical measurements and acceleration algorithms under median 

operating conditions. MTBF ratings are not intended to predict an 

individual drive’s reliability. MTBF does not constitute a warranty.
