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

Buffer capacity includes 270 or less KB used for drive firmware.

Does not include command overhead

Low duty cycle, non mission-critical applications in PC, nearline and consumer electronics customer environments

are different from application to application .

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.

Example: HDT725050VLA360 = 500GB/16MB H = Hitachi D = Deskstar T = Two- or three-disk 72 = 7200 RPM 50 = full capacity = 500GB 50 = model capacity = 500GB

(40 = 400GB, 32 = 320GB, 25 = 250GB)

V = generation code L = 1-inch form factor A3 = SATA 3.0 Gb/s (AT = Parallel ATA) 6 = 16 buffer (8 = 8M buffer) 0 = Reserved
