One MB is equal to on 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 for-
matting and partitioning of the hard drive, the computer’s operating system,
and other factors.

Intended for lower duty cycle environments in the enterprise storage
hierarchy such as nearline applications. 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.
