IBM Travelstar 25GS - hard drive - 25.3 GB - ATA-66

IBM provides a leading-edge technology and innovative design for high-performance, high-capacity mobile hard drives. The company offers its Travelstar 25GS hard drive. An advanced electromechanical design provides exceptional storage capacities and superior shock ratings to improve reliability and ruggedness. These advanced hard drives combine IBM giant magnetoresistive (GMR) head technology, Partial Response Maximum Likelihood (PRML) digital channel, a head load/unload feature, a more rigid base casting than previous models, and Enhanced Adaptive Battery Life Extender (ABLE) 3.0, and they're developed using state-of-the-art manufacturing techniques. Fast Ultra-DMA interface transfer rates reach as high as 66 MB/sec. In addition, these new IBM drives employ a thermistor, an adaptive control device that helps maintain high performance and fast seek times at high environmental temperatures. IBM Travelstar drives include IBM Drive Fitness Technologies, a set of diagnostic tools including IBM Drive Fitness Test (DFT) and Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.).
