Leading drive technology
The Ultrastar 2XP disk drive is optimized for superior performance and capacity, and incorporates the industry's most advanced recording and manufacturing technologies. By combining IBM's leading drive technologies such asMR heads, No-ID (TM) sector formatting and PRDF (PRML with digital filter) channel, the Ultrastar 2XP offers enhanced capacity, performance and reliability, with an areal density of 829 Mbits per square inch. No-ID sector formatting eliminates the overhead caused by the duplicate storage of each data sector's ID field on the disk, and instead uses that space for additional customer data. The unique PRDF data channel produces lower soft error rates and enables higher data throughput.
The superior performance of the Ultrastar 2XP drives is a result of a combination of several factors. The drives offer a 7200 RPM rotational speed and a data access time under 8.5 ms. Outstanding areal densities, combined with a high-speed channel, provide the Ultrastar 2XP drives with a media data rate of 10.3-15.5 MB/sec. The average sustained data rate of 9.2 MB/sec. is ideal for multimedia and audio visual systems that require higher throughput.
