Deskstar T7K500
The Deskstar T7K500 builds on Hitachi’s
award winning tradition with new 160GB per
platter areal density technology. Consumer
personal computers and low duty cycle servers
demand high capacity and high performance
storage to meet consumers digital media
needs and growth ATA server application
requirements. The Deskstar T7K500 meets
these performance requirements and delivers
the high capacity for today’s applications.

Hitachi’s standardized features in consumer and low duty cycle server solutions enable faster
transfer rates, scalable performance and quicker boot up times.
Hitachi is dedicated to providing a breadth of hard disk drive products to satisfy all of today’s
demanding computing needs. Hitachi hard drives are backed by an array of technical support
and services which may include customer and integration service.

Hitachi Global Storage Technologies
1GB equals one billion bytes when referring to hard drive capacity; accessible capacity may be less.
2Buffer capacity includes 270 or less KB used for drive firmware.
3Does not include command overhead
4Low 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.
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:
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
