RoHS compliant⁵

Yes

¹ GB equals one billion bytes when referring to hard drive capacity; accessible capacity may be less.

² Buffer capacity includes 260 KB used for drive firmware.

³ Includes command overhead.

⁴ Low duty cycle, non mission-critical applications in PC, nearline and consumer electronics customer environments are different from application to application

⁵ RoHS refers to the European Union Directive 2002/95/EC on the restriction of certain hazardous substances in electrical and electronic equipment
