<P>The IBM Ultrastar 18ES hard disk drives offer exceptional performance with 9.1 gigabytes (low profile) and 18.2 GB of capacity, rotational speeds of up to 7,200 RPM, and average seek times as fast as 7.0 ms. A large 512kb buffer also provides outstanding performance, especially for data-intensive applications that access data sequentially. The Ultrastar family is specifically designed for servers and high-end workstations running a range of applications -- from collaborative workgroup applications to image processing, video editing to data mining, and online transaction processing to online analytical processing. The Ultrastar family delivers high sustained data rate performance through the combination of Magnetoresistive Extended (MRX) advanced head technology, an embedded digital servo, efficient No-ID sector formatting, and a fifth-generation Partial Response Maximum Likelihood (PRML) data channel with enhanced track ID detection. S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology)-compliant Predictive Failure Analysis (PFA) and Drive Temperature Indicator Processor (Drive-TIP) monitors enable the Ultrastar 9LP, 18XP, and 9ZX to report significant changes or impending failures when pre-programmed thresholds are exceeded.</P>
