IBM DDRS-34560 hard drive specifications

IBM Ultrastar 9ES - hard drive - 4.5 GB - Ultra2 Wide SCSI

As a member of the IBM Ultrastar family of disk drives, the Ultrastar 9ES is designed to provide a reliable, cost-effective storage solution for a wide range of workstations, high-performance desktop systems, and LAN servers running Internet/intranet, CAD/CAM, and multimedia applications. The Ultrastar 9ES achieves its high level of reliability, performance, and affordability by leveraging IBM's development and implementation experience in advanced disk drive technologies. These include Magnetoresistive Extended (MRX) advanced head technology, No-ID sector formatting, the Partial Response Maximum Likelihood (PRML) digital data channel, and a new integrated LSI chip. MRX advanced head technology increases areal density and reduces the number of disks and heads required for a given capacity. No-ID sector formatting increases storage capacity by eliminating overhead caused by the duplicate storage of each data sector's ID field onto the disk, which thereby creates more available disk space for data. PRML enables higher areal densities and significantly enhances the drive's overall performance by increasing media-to-buffer and buffer transfer rates.
