1 GB equals one billion bytes when referring to hard drive capacity; accessible capacity may be less.
2 Upper 417KB reserved for firmware.
3 Intended for low duty cycle, non mission-critical applications in PC, nearline, and consumer electronics
environments, which vary from application to application.
4 RoHS refers to the European Union Directive 2002/95/EC on the restriction of certain hazardous substances in electrical and electronic equipment.
