1 Intended for use in lower duty cycle environments in the enterprise storage hierarchy such as nearline applications. This MTBF rating 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.
2 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.
3 Portion of buffer capacity used for firmware.
4 Excludes command overhead
