[. . . ] Dprs2xxx. dat 2. 5-Inch Travelstar XP 810 MB and 1. 2 GB Disk Drives Models DPRA-20810 DPRS-20810 DPRA-21215 DPRS-21215 The new Travelstar XP drive delivers the highest capacity in a 2. 5-inch form factor. Available in 1. 2 GB, an 810 MB configurations, the drive was developed to offer the enhanced performance and value required for notebook applications demanding fast access to large amounts of data. [. . . ] The drive features 4900 RPM while maintaining a low power dissipation. Travelstar XP drives achieve this by incorporating advanced power management electronics to minimize current draw--a critical consideration in battery-powered mobile computing systems. To ensure data integrity in transport, Travelstar XP drives undergo extensive testing and will withstand 100 Gs of operating shock and non-operating shocks of 300 Gs. In addition, these drives are engineered to withstand over 52, 000 contact start-stop cycles, and offer over 300, 000 power-on hours MTBF. Quality and reliability ----------------------All IBM drives are manufactured to stringent standards for quality and performance, with sensitive components assembled in a rigidly controlled clean environment. Extensive quality control and testing procedures are used throughout the manufacturing process to ensure product reliability and data integrity.
