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 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.
