1  One GB is equal to one billion bytes and one TB equals 1,000 GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity may be less.

2  Intended for use in lower duty cycle environments in the enterprise storage hierarchy, such as RAID and nearline applications. This MTBF target 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.

3  Portion of buffer capacity used for firmware

4  Excludes command overhead

The EcoTrac symbol identifies Hitachi hard drives that deliver on 
the principles of lower operating costs, safer product disposal 
and a more sustainable environment.
