Enhanced performance, value and reliability for workstation, performance desktop, and server PCs

Highlights

Enhanced performance
Average seek time of 8.5 ms and minimum sustained data rates of 5.1 MB/sec. (4.3 GB) and 5.0 MB/sec (2.1 GB) provide the performance needed to meet today's data-intensive application requirements.

Superior capacity
1.44 GB per platter capacity enhances performance in a broad range of workstation, desktop and server PC applications.

Low power dissipation
Through efficient electronic design, combined with IBM leading disk drive technology, the Ultrastar 2ES significantly enhances value and reliability.

Improved data performance
PRML digital data channel delivers increased media-to-buffer and buffer transfer rates for performance leadership.

Enhanced SCSI storage performance
Ultra-SCSI interface delivers the high-throughput capabilities required by workstations, high-performance desktop PCs, entry servers, and LAN servers.

Data protection
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) protocol support protects data availability and helps alert a system of impending drive failure.

Leading drive technology

The Ultrastar 2ES drive achieves its reliability, performance and cost-effectiveness by taking advantage of IBM's development and implementation experience in advanced disk drive technologies. These technologies include Magneto-Resistive heads, No-ID sector formatting, and the Partial Response Maximum Likelihood (PRML) digital channel.

MR heads offer increased areal density, reducing the number of disks and heads required for a given capacity. No-ID sector formatting further increases storage capacity by eliminating the overhead caused by the duplicate storage of each data sector's ID field onto the disk, creating more available disk space for customer data. The PRML digital channel now implemented on IBM's newest desktop drives such as the Ultrastar 2ES allows for higher areal densities and significantly enhances the drive's overall performance.

The combination of these three leading technologies, along with the proven electronic design of the Ultrastar 2ES, provides the performance and reliability to meet today's performance desktop, workstation and server storage requirements, while delivering superior value.

SCAM-2 (SCSI configured automatically) compliant

Ultrastar 2ES drives support the implementation of SCAM-2. This support increases the user's productivity by simplifying and improving the installation and configuration of SCSI disk drives.

Interface

To accommodate different system requirements, the Ultrastar 2ES drives are available with an Ultra-SCSI interface (SCSI-3 Fast-20) in multiple configurations: 50-pin Single-ended, 68-pin Single-ended Wide, and 80-pin SCA-2 Single-ended Wide.
