User manual HITACHI ULTRASTAR 18XP DATASHEET

[. . . ] Superior performance, reliability, and capacity for advanced enterprise server applications IBM Ultrastar 9LP and 18XP Hard Disk Drives Highlights Superior capacity Capacities of 9. 1 and 18. 2 GB and an areal density of 1. 2 Gbits/square inch provide superior storage solutions. High performance at 7200 RPM Average seek times as low as 6. 5 ms and maximum sustained data rates of up to 15. 5 MB/sec provide rapid data transfer. [. . . ] Leadership reliability IBM continues its leadership tradition of providing drive failure protection through S. M. A. R. T. (Self-Monitoring Analysis and Reporting Technology), IBM Predictive Failure Analysis* (PFA), and the new IBMexclusive Drive-TIP . These features monitor key device performance indicators and temperature, reporting significant changes, warnings, or impending failures when predetermined thresholds are exceeded. Ultrastar 9LP and 18XP drives also employ advanced Error Correction Code (ECC) technology throughout the recording process. Support for advanced applications Improvements in data throughput are increasingly important in advanced applications, such as video editing, multimedia, and data mining. Ultrastar 9LP and 18XP drives provide the necessary high sustained data rates by combining industryleading Magnetoresistive Extended (MRX) advanced head technology, an embedded digital servo with efficient No-ID* sector formatting, a powerful ECC "on-the-fly" implementation, and the IBM advanced Partial Response Maximum Likelihood (PRML) digital data channel. Advanced interfaces IBM offers a comprehensive set of SCSI and serial host interface solutions for the server industry, including Ultra SCSI and Serial Storage Architecture (SSA).
