Great performance and reliability provide high value for a wide range of performance desktops, workstations, and PC servers
IBM Ultrastar 9ES Hard Disk Drive
Highlights
Enhanced performance
Average seek times of 7.5 ms and minimum sustained data rates of 8.3 MB/sec provide high performance for a variety of PC, workstation, and server applications.
Industry-standard capacities
At 4.5 and 9.1 GB, the Ultrastar* 9ES provides the storage required by a broad range of data-intensive applications.
Extremely low power dissipation
Through efficient electronic design and a new integrated LSI chip, the Ultrastar 9ES provides the industry’s lowest 7200 RPM idle power, helping to improve reliability and ease of integration.
Proven IBM reliability
With a reputation for quality and reliability, IBM SCSI drives provide excellent cost-of- ownership benefits to system integrators.
Low acoustics
With acoustics matching IBM’s previousgeneration 5400 RPM drives, the Ultrastar 9ES provides excellent human factors qualities for workstation and desktop PCs.
Exceptional data protection
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) protocol support alerts systems of impending drive failure and helps ensure data availability.
Leading drive technology
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.
IBM and Mitsubishi have developed an integrated LSI chip that incorporates a microcomputer, hard disk controller, and flash memory in a single chip.This design helps to increase performance, reduce power usage, and enhance reliability.
SCAM-2 (SCSI Configured Automatically)-compliant
Ultrastar 9ES drives support the implementation of SCAM-2.This support may increase user productivity by simplifying and improving the installation and configuration of SCSI disk drives.
Flexible interfaces
To accommodate a wide range of system requirements, Ultrastar 9ES drives are available with an Ultra-SCSI interface in multiple configurations: 50-pin Singleended, 68-pin Single-ended Wide, and 80-pin SCA-2 Single-ended Wide.
