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

2Buffer capacity includes 271 KB used for drive firmware.

3Includes 0.3ms command overhead.

4Low duty cycle, non mission-critical applications in PC, nearline and consumer electronics customer environments are different from application to application. An MTBF measurement is based on a sample population and is estimated by statistical measurements and acceleration algorithms under nearline / low duty cycle workload. MTBF ratings are not intended to predict an individual drive’s reliability. MTBF is not a warranty measurement.

5RoHS 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.

How to Read the Deskstar Model Number

Example:

HDS725050KLA360 = 500GB/16MB

H= Hitachi D = Deskstar

S = Standard (vs T for Two-disk for example)

72 = 7200 RPM

50 = full capacity = 500GB

50 = model capacity = 500GB (unless 1 in last position) K = generation code

L = height

A3= SATA 3.0Gb/s

6 = 16MB buffer

0 = 500GB model (1=400GB mode
