1 GB equals one billion bytes when referring to hard drive capacity; accessible capacity may be less.
2 Buffer capacity includes 271 KB used for drive firmware.
3 Includes 0.3ms command overhead.
4 RoHS refers to the European Union Directive 2002/95/EC on the restriction of certain hazardous substances in
electrical and electronic equipment.
Specific application environments such as temperature and duty cycle will affect the overall reliability rates. For specific application environment reliability rates, please consult Hitachi technical support.
