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.

2

MTBF and AFR targets are based on a sample population and are

estimated by statistical measurements and acceleration algorithms

under median operating conditions. MTBF and AFR ratings do not

predict an individual drive’s reliability and do not constitute a warranty.
