Deskstar
 5K4000
3.5-INCH HARD DISK DRIVES
CoolSpin design for desktop systems
The Deskstar™ 5K4000 hard drive provides an enormous 4TB capacity and features innovative 
CoolSpin technology to deliver a greater level of power efficiency and quiet operation for 
energy-conscious, environmentally-friendly computers. This drive uses Advanced Format, 
which increases the sector size on HDDs from 512 bytes to 4096 (4K) bytes, thereby increasing 
capacities and improving error correcting capabilities. Consult the Hitachi Advanced Format 
Technology Brief for more information. CoolSpin technology is an optimization of motor speed 
to provide an ideal balance of performance, power utilization and acoustics. With low power, 
high capacity and cool operation, the 3.5-inch Deskstar 5K4000 helps manufacturers deliver 
more eco-friendly systems. Manufacturers planning to use the 4TB drive in systems should 
consult the Hitachi High Capacity Technology Brief.
Power efficient for cooler operation and longer life
The CoolSpin technology, along with other Hitachi power management techniques, gives the 
Deskstar 5K4000 its 28% power savings over the Deskstar 7K3000. HiVERT technology helps 
efficiently manage power consumption. These innovations, along with eighth-generation  
Advanced Power Management, make the Deskstar 5K4000 the ideal choice for energy-
efficient PCs that run cooler, require less power and last longer.
Innovation for a more sustainable environment
The Deskstar 5K4000 demonstrates Hitachi ecological leadership with its halogen-free design 
and power-efficient operation. Both of these features helped qualify the drive for the Hitachi 
EcoTrac classification, which identifies products that minimize environmental impact in the 
areas of product design, manufacturing, operation and disposal.
