RoHS compliant
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
Low 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.
5
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:
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
