Performance, quality and reliability
Designed with mobile life styles in mind, the Travelstar 4K40 leverages proven technologies
such as True Track Servo, which eases system integration, enhances hard disk drive reliability,
and adds robustness against vibration and disk shift, Drive Fitness Test™ (DFT), Self-Moni-
toring Analysis and Reporting Technology (S.M.A.R.T.) to enable a hard drive to predict
impending catastrophic failure, and an adaptive control algorithm to help maintain high
performance and fast seek times at high environmental temperatures.
The Travelstar 4K40 is based on an industry
leading design that has been made even better.
Simply put, it is hard drive artistry!
