Cutting-edge storage technology

Redefining state-of-the-art storage for

mobile computing, Hitachi introduces the

new Hitachi Travelstar C4K40, 1.8-inch,

4200 rpm hard disk drive. Available in 20

and 40 GB, the Travelstar C4K40 leverages

the award-winning Travelstar technology

legacy in a new form-factor, providing high

capacity storage for a wide range of por-

table mobile equipment.

Designed with Fluid Dynamic Bearing

(FDB) motor technology, Giant

Magnetorestistive (GMR) heads, and a

ME2PRML read channels for exceptional

quietness and performance required by

today’s demanding computing needs.

Ideal for PC, non-PC, and removable mobile storage applications

Delivering both high-capacity and per-

formance, light-weight, with a small form

factor, the Travelstar C4K40 is an ideal

storage device for not only traditional com-

puting needs, but also for non-traditional

products such as handheld PDA’s, MP3

players, printers, fax-copiers, and other

removable storage devices.

Performance and reliability

Incorporating both a shock sensor and

Self-Monitoring Analysis and Report

Technology (S.M.A.R.T.), the Travelstar

C4K40 is well equipped to help maintain

high-performance and fast seek times in

applications that require a rugged, slimline

form factor.
